Robinson® Backscattered Electron Detector
The spatial resolution of the Robinson BSE Series 8.6 Detector is so good, images of human tissue are almost indistinguishable from a TEM image of the same sample! No other BSE detector comes close in resolution, not the one that come "installed" with new SEMs or from others trying to copy the innovative scintillator detector based design of the Robinson system. Contact SPI Supplies for customer installations anywhere in the world. The system is designed and shipped so that it can be easily customer installed. And for those working with large samples, such as kidney biopsies, and since a TEM is limited to what can be put onto a 3 mm TEM grid, the fact that samples of much larger size can be examined by SEM and BSE make the Robinson Detector approach highly desirable in any number of new applications. |
No this is not a TEM image but it was done with the new Robinson Series 8.6 BSE detector on a JEOL 6700F FESEM |

SPI Supplies® Brand Portable Fume Hoods We feature the SPI Supplies Brand® Ductless Portable Fume Hoods so that laboratory personnel can work much more safely without exposure to dangerous and toxic fumes, and at the same time, without spending large amount of money to install vents through walls and building roofs, something in leased or rental facilities that might not even be permitted by the building owners. The SPI Supplies Brand Ductless Portable Fume Hoods exceed OSHA, ANSI and all other relevant international standards for worker safety. Nothing is sacrificed, and certainly not in terms of safety, when a ductless fume hood is used relative to a conventional (ducted) fume hood. |

Allred™ substrates from titania and precious metals: These represent a class of grid-based products that are, in essence, "TEM support films", but they are really much more than support films. They are designed for "processing", that is, for coating, deposition and other kinds of treatments and yet, with the final often times multi-layer "composite" sufficiently electron transparent so that it can be characterized by TEM without further sample preparation. The films are also sufficiently rigid so that one can also do FESEM and under some circumstances, SPM as well. In addition, these coatings are extremely thin, in fact thinner than one can normally make, ranging from ~ 2 nm for the precious metal films up to ~ 5 nm for the titanium dioxide films. Currently, platinum, gold, palladium and titania are all available as grid support films. |

SPI Supplies® Brand Silicon Nitride Membrane Window Grids for TEM Use these grids for your most exacting work instead of a conventional TEM grid. The membrane is highly electron transparent, and is also completely amorphous, and is therefore structureless and featureless. Use for high temperature in situ TEM studies. Use for nanoparticle and carbon nanotube imaging without annoying artifacts from the typical carbon film. Obtain more accurate spatial measurements because grid "sag" is now eliminated. These grids are dramatically more expensive than conventional grids but since the work can be done so much more quickly, and with far less need to do grids over again, some customers tell us that in the long run, the use of these unique grids saves them money! |

SPI Wet Cell™ Kits for SEM and BSE Applications Examine biological samples "live" in the wet cell made from the SPI Supplies silicon nitride membrane window grids. Resolution is determined by the membrane thickness and the 20 nm silicon nitride membrane thickness, which is far thinner than any polymer membrane, permits an up-until-now an impossible to achieve resolution using a wet cell and backscattered electron imaging techniques. The wet cell approach can be used for the characterization of emulsions, liquid suspensions and other otherwise difficult to examine wet samples. |

SPI Supplies® Brand Perforated Silicon Nitride Membrane Window Grids for TEM:
Use these grids as a higher quality holey carbon grid for TEM. Using the very latest MEMs technology and processing techniques, we have been able to greatly reduce the costs for making the perforations and can now offer in essence an array of holes, 2µm in diameter on 4 µm centers. When used as a TEM support film, the samples are far more stable and customers experience noticeably less image drift during viewing. |

Aquamarijn™ MicroSieve Membrane Filters:
Using the very latest of semiconductor and MEMS processing techniques, we are able to produce highly uniform holes in silicon. The product displayed on this page is the first product in what will be a much wider family of filtration products of different pore sizes and pore densities. The present product consists of an active filter membrane which has dimensions of 0.45 x 0.45 mm square mounted into a filter disk 47 mm diameter and which is designed to fit into any standard 47 mm diameter filter holder. The applications for this innovative filtration media are still being discovered |

MACO™ Electron Microscope Film:
What is a disaster for some could be great opportunities for others. With the rapid decline of the conventional photographic market, emulsion products of all types are being discontinued right and left. Not wanting to leave our customers out on a limb, and with the film supply some day abruptly ending, we have worked with MACO, a firm that specializes in "taking over" the production of discontinued emulsion products, to develop a plug in compatible replacement for Kodak SO-163 and Agfa Scientia® 23D56. And at the same time, they have developed the new MACO ES film, a replacement for Kodak 4489. And because we are at the same time, eliminating the high cost distribution model that the large global photographic industry manufacturers are known to have, we can offer the film at a substantially reduced price relative to the pricing, for example, of SO-163 or 4489. Since we have adopted flat rate shipping/handling/insurance fees for shipment to most countries in the world, so long as you are ordering other items, it is as the shipping costs for you would be free. So if you are one of those laboratories being hard pressed to make limited budget dollars stretch farther, and don't have the funds to "go digital", don't let another day go by without placing your first order for MACO™ Electron Microscope Film. |

ITO (Indium-tin-oxide) Coated Microscope Slides
Take advantage of the new ITO-coated substrates now being produced by SPI Supplies. All you have to do is connect electrical leads (to put a voltage potential across the slide) and the slide will be uniformly heated, higher even than the boiling point of water (if desired). High transparency (from UV to NIR) ITO coatings have applications not only for microscopy but any time planar, electrically conductive surfaces are required that have the just indicated transparency. Our coatings are also used by researchers in the areas of liquid crystal display technology, polymer light emitting diode technology and related applications. |

Secador™ Desiccator Cabinets
The new Secador desiccating cabinets form an entire family of desiccator products, known for their very high quality but with economical prices. They are intended for both long and short terms storage of critical laboratory samples that must be stored in a dry, dust-free environment. They feature a new contemporary design and would fit right into the environment of any modern laboratory anywhere. With the auto desiccating option, these cabinets never need to have desiccant changed, and thereby eliminating a particle contamination source prevalent in conventional desiccator chambers. |

SPI Supplies® Brand PTFE Labware
PTFE labware in the laboratory provides containers that for some highly aggressive chemicals can be contained only in PTFE. The starting materials used for the manufacturer of the SPI Supplies family of PTFE labware are either 3M Company (Dyneon®), Asahi Chemical (Fluon®) or other major producers of high quality PTFE depending on the particular item. It is also resistant to steam and has a temperature range of use covering the range of -200°C (390°F) to + 300°C (+570°F). Because of the three dimensional structure of PTFE at the molecular level, it is essentially intractable in any solvent, therefore explaining it unique resistance to dissolution in most solvents or strong acids and bases. But if a beaker or other item is accidentally dropped, it won't break as would its glass counterpart. PTFE labware have a place in any laboratory's safety program. |

Pikal® Paste for Metal Polishing
Pikal® paste is not just another metal polish: It is a superb metal polish. It has been formulated with an abrasive system that will not scratch highly polished surfaces being exposed to conditions of UHV and it contains a carrier (e. g. the suspending liquid) that quickly evaporates leaving a surface that, when reinserted into the UHV environment, will quickly pump down and not present problems with long time off-gassing. JEOL® and other fine EM manufacturers have traditionally shipped a trial can of PIKAL paste with all new column instruments so that new customers will start out "on the right foot" and use the best possible cleaning protocols for their important instruments. |

SPI Supplies® Brand Quartz Microscope Slides and Cover Slips
There are many microscopy laboratory operations and procedures where UV transparency is an absolute requirement. There is of course the obvious case where one might be doing UV microscopy, but there are also other applications where one is irradiating a sample with UV irradiation and quartz must be used for the container of the liquid being irradiated. Select from the largest range of off-the-shelf sizes of microscope slides and cover slips including the difficult to make thickness #1 (0.15 to 0.18 mm). |

Paper Fiber Stains: Reliable stains originally developed by the Institute of Paper and Science Technology, Atlanta, GA and now available from SPI Supplies Fiber stains provide contrast and aid in the identification of pulp and paper fibers by light microscopy. The most widely used is the Graff "C" stain, developed at the Institute in the 1930's. Stain applications include differentiating chemical pulps from ground wood, and bleached from unbleached fibers. They can be used with most natural cellulose fibers, including cotton. SPI Supplies is the source for these unique and well known stains. |

Reintroduction! SPI-Pore Silver Membrane Filters: Originally developed in the early 1970's, the SPI-Pore brand of silver membrane filters has been widely used not only as a conductive substrate for SEM examination of filtered particulates, but biological samples (e.g. cells or groups of cells) can be critical point dried just like for polymer membranes. The highest volume usage of the SPI-Pore Silver Membranes is for the determination of free silica by x-ray diffraction. The product line was temporarily not being produced for approximately one year, but now it is back and SPI stands ready to fulfill orders from stock. Standard sizes are 13, 25, 37 and 47 mm diameter. |

Quantifoil® Micromachined Holey Carbon Grids: Quantifoil is a perforated support film with a precisely pre-defined hole size, shape, and arrangement. The use of these support foils as "support films" on TEM grids offers a number of advantages not only for conventional transmission electron microscopy (TEM), but also for low-energy point source (LEEPS) microscopy when compared with conventional holey carbon support films. Of course, if you don't need the ultimate holey carbon films, then remember you can still purchase the standard holey carbon films made by SPI Supplies using more conventional methods. Or for high temperature studies, or use with nanoparticles, consider the unique SPI Silicon Nitride Membrane Window Grids. |

Uniquely Numbered SEM Mounts for Forensic Laboratories: Each mount is uniquely numbered for total chain of evidence management, something that all too often is mismanaged in the typical SEM laboratory setting. These SEM mounts are all uniquely numbered and SPI will never make a second mount with the same number. Presently, the numbered SEM mounts are available as "standard" SPI products, as stock items, for three of the most popular selling mounts. Every forensic SEM laboratory should consider switching to the SPI numbered SEM mounts. |

OPC-80N Osmium Plasma Coater: For users of FESEM instruments in particular, this new model of this compact unit offers a coating that is amorphous and therefore one that exhibits no grain size. It also deposits a coating that is completely inert, won't change with time, and has a major advantage over chromium coating since chromium after a very short time has oxidized beyond the point where the sample would still be conductive for examination by SEM. Up to 4 individual samples can be coated at one time in this newest model of this exciting technology for metallizing SEM samples. |

What is SPM Calibrator™?: Until the invention of SPM Calibrator, the calibration of SPM instruments was time consuming and laborious, so much so in fact, that even busy quality laboratories were being hard pressed to take the time needed to do proper and timely calibration checks. SPM Calibrator solves that problem, and is a product no respectable SPM lab could afford to be without! |
 |
|
Molybdenum disulfide crystals: Another excellent prospective substrate for those doing scanning probe microscopy, in particular, for those doing experiments where there is the need to adhere organic molecules to the substrate. |
|

ACLAR® Fluoropolymer
Film: For tissue culture and epoxy embedding applications! This is the "miracle" film that everyone now is turning to for tissue culture and embedding applications. This is a polychlorotrifluoroethylene copolymer and this particular composition results in a film with very excellent optical properties, as well as good thermal and chemical stability. It also serves as an excellent moisture barrier. The high UV transparency of this particular grade of ACLAR makes it idea for use in the UV curing of resins in microscopy and histology. |

SPI Microporous Specimen Capsules now with 30 µm Pore Size:
These unique capsules were designed specifically for specimen processing and critical point drying of small samples. A special treatment makes the pores "wettable" by the processing fluids, thereby enhancing and speeding up the processing times that would otherwise be needed. Dried samples can be photographed directly by cutting open a capsule, metallizing, and then inserting into the SEM. Two other pore sizes are available: 70 and 120 µm. |
|
|
SPI Supplies Brand Molybdenum TEM Grids that are only 30 µm thick:
SPI now offers the widest selection of moly grids for TEM in the world. We produce them to a thickness of only 30 µm, much thinner than what is made by other producers (often times 50 µm or more!). Anyone doing tilting studies would appreciate instantly the far higher value of using thinner rather than thicker grids. And for those doing low angle ion milling, one could not use very well a 50 µm thick grid but if using a 30 µm slot grid, well, the entire process becomes much easier! |
 |
|
SPI Tacky Dot® Array Slides: For the mounting of fine powders for faster and more accurate analyses. If you have stage automation on your SEM or LM, then powder samples can be usually characterized in a fraction of the time that would otherwise be needed if Tacky Dot Slides are being used. Through the use of the Circle Analytical Mount holder, one can prepare powders in arrays, in cross-sections. |
|
|
SPI PTFE Printed Slides:
For those life sciences researchers wanting to save money by minimizing the use of expensive immuno-reagents. |
|
|
SPI Stain 'N Wash™ Grid Staining System: This outstanding, yet inexpensive product was designed to save money by reducing the volume used of expensive immuno-reagents. |
|
|
Diamond grids: For ion milling specimen supports and high resolution low drift rate TEM or low background STEM work. Diamond has four times the heat carrying capacity of copper, therefore heat can be carried away four times faster during ion milling, resulting in heat sensitive samples running at lower temperatures. |
|
|
HOPG Substrate Material: For scanning probe microscopy and also those doing thin film research. SPI Supplies offers two different "brands" of HOPG, and in the SPI brand, larger pieces than ever before offered commercially are now available. |

Apiezon® N Cryogenic High Vacuum Grease: When it comes to low temperature applications, nothing comes close in performance to Apiezon N Grease. The product retains most of its important properties all the way down to -269°C/-452°F/4°K. But this is not all. This innovative new lubricant solution to those low temperature challenges can also be cycled from these low temperatures up to room temperature and then back down without showing visible signs of cracking. |
|
|
Perfluorosolv® PFS-1 Perfluorinated Cleaning Solvent: This is a highly useful CFC-Free cleaning substitute for ozone depleting solvents. The product is a low molecular weight perfluoropolyether solvent and diluent that can be used as a replacement for CFC-113 and other ozone depleting solvents being restricted by the governments of the world. It has found application for the removal of Y-VAC® 3 and Braycote® greases from "o" rings and other surfaces.
