The SPI Supplies® Brand PTFE Printed Slide is a screen-printed microscopic slide for immunofluorescence testing. Coating thickness is controlled to be about 0.02 mm (20 Ám) with fairly low variation from point to point on the printed surface. That part of the slide covered with the PTFE coating is very hydrophobic, can be autoclaved, and is very resistant to almost all chemicals including HF. And it is inert in the presence of virtually all laboratory solvents. And the printing is done on slides with 90° round edges.

Resistant to acetone, methanol and Phosphate Buffered Saline(PBS), the PTFE coating has extreme hydrophobic properties which prevent cross contamination and increase well capacity.

The well surface is 100% wettable which provides for an enhanced cell attachment as well as an excellent spreading of the antigens within the well - making it economical, because you will be using less of the expensive purified antigens and monoclonal antibodies. Customers continually tell us that the cost of the slides is very small compared to the cost of the immuno reagents they save by using this system.

The SPI PTFE Printed Slides are manufactured and packaged to provide maximum possible shelf life. While the generally given shelf life for slides is usually given as being up to about 18 months when stored under normal laboratory conditions, this life time can be extended greatly by ensuring that the slides are stored in a dry environment.

We guarantee the SPI PTFE Printed Slides to be autoclavable. The slides are intended for a single use only and one should not try to reuse them. We are unaware of anyone who has successfully been able to do that, since the results on the "recycled" slides tend to be quite variable when compared to the originally purchased slides.

Standard deviation of the position of the pattern on the slides:
A growing number of users of the PTFE slide technology are having the slides analyzed in automated equipment, and this demands that there be very close tolerances for the reproducibility of the positioning of the pattern on the slides. Our standard tolerances for the printing are ▒0.5 mm. We are proud of this low standard deviation; not many manufacturers are brave enough to publish their tolerances!

Custom manufacturing:
A growing portion of our business is custom printing of special patterns for customers with specific requirements. With the SPI printing technology, we can generally beat just about anyone's best definition of detail, meaning also that we can make the very smallest wells anyone has ever seen! For a custom slide printing job, with slide sizes restricted to maximum size 1x3" (76x26 mm), the best economics start to emerge when 20 boxes of 100 slides are the minimum quantity.

The SPI PTFE Printed slides measure 1x3" (76x26 mm) and packaged 100 slides per box. At the present time, our tooling exists only to process slides of this size and we are unable to print slides either larger or smaller than this size.

Choice of color:
The slides are available either in maroon or black, depending on how they are portrayed on this page.

Storage conditions:
All glass slides have a limit to their shelf life because of the phenomenon called "glass corrosion", which results in a frosting of the glass surface. The rate at which this happens can be slowed down literally to a crawl by the way the slides are stored, and that is to keep them away from temperature fluctuations. They should be stored preferably near room temperature and should be insulated from any severe temperature fluctuations.

Packaging:
All slides packaged and priced in boxes of 100
