SPI Logo Slide-A-Grid Storage Box

Our experienced in-house TEM operators and grid makers won't touch any other grid boxes except these two boxes that carry the SPI Supplies name! Use the SPI Slide-A-Grid™ box for up to 100 grids and the new SPI Twist-A-Grid™ box for up to 50 individual grids. Note that the new Twist-A-Grid box, for the first time, is designed for stacked storage. Both boxes are available numbered or unnumbered.

These two SPI Supplies Brand TEM grid storage boxes are our most often asked for grid storage boxes. The original box was known worldwide as the SPI Slide-A-Grid Storage Box and the new Twist-A-Grid TEM grid storage boxes is being widely accepted an improvement in design because of the stability feature. Each box holds either 100 or 50 3.05 mm TEM grids in a combination of number/letter coded compartments. Each box is accompanied by a record card for the convenient logging and indexing of your stored (or waiting-to-be-looked-at grids). So far as we know, this box is compatible with virtually all 3.05 mm (e.g. nominally 3 mm) TEM grids, including the unique SPI Silicon Nitride Membrane Window Grids.

Note these advantages over grid boxes from other manufacturers:

Anti-static Plastic:

The plastic formulation used is straight out of the aerospace and electronics industries greatly reduces tendency of the grids to jump out of or stick to the slots in the box.

Numbering System:

A unique numbering system is available to uniquely identify each Slide-A-Grid or Twist-A-Grid box from any other grid box, since no two boxes carry the same number. Any particular row of grids can be selected using the slot in the clear PVC see-through cover.

Note When Ordering:

Be sure to select between the "numbered" vs. "unnumbered" varieties of boxes. Generally speaking, the numbered boxes are slightly higher in cost than the boxes without numbers.

Special Note on the Numbered Boxes:

For quantities purchased in multiples of five boxes, they are packaged five per bag, and within a bag, the boxes are uniquely and sequentially numbered. We can not supply sequential numbering for more than any five boxes, that is, a second bag of five will be sequentially numbered, but would be of a different sequence from any other bag. For a purchase of a bulk box of 250 boxes, within that entire box, will be 250 boxes sequentially numbered.

Grid Record Keeping Card:

Each SPI Slide-A-Grid™ Storage Box is accompanied with a convenient grid record keeping card and a plastic polybag for safe storage. This is true for when the boxes are sold individually or in bulk packaging.

SPI Twist-A-Grid™ Storage Box:

The new Twist-A-Grid storage box is designed for the routine handling and long term storage of 50 standard size TEM grids. This new ergonomic design incorporates several features that overcome the disadvantages associated with storage boxes of the more conventional 'sliding cover' design. The numbered version has a unique number on the face and one end. There is slight additional cost associated with the numbering so the numbered boxes cost slightly more than the same box without the numbers.
