  • All timings given are representative and should be adapted to your particular laboratory conditions.
  • All silver stains should be performed in acid cleaned glassware for best results.
  • Use only deionized or distilled water, unless otherwise directed.
  • Most working solutions, once made, should be used immediately.
  • All solutions are individually labeled with expiration dates and storage conditions.
  • All procedures are written for manual use, but all can and have been adapted for any automated stainer.

What Our Customers Say

I would like to thank you and all of the wonderful people at Poly Sci for all of their support, dedication, and true sense for caring. I have worked and used the Poly lab products since 1980. The quality and reliability has been very good and has really helped in getting our work completed with very good results time and time again. If ever we had any questions their Administrative staff and Technical people are always available to talk and help us out in the field, this has really made a difference on our side with Poly providing “Top Notch” customer service, especially while working in this current COVID-19 world pandemic. Thank you!!


I have worked in the histology field for over 40 years, 37 of them in the Technical Director/ Supervisor position of both private reference laboratories and teaching hospitals in the Boston, Massachusetts area. During those 37 years, I have used Poly Scientific R&D reagents exclusively for routine hematoxylin and eosin (H&E) staining and special stains. In all that time every pathologist who has reviewed slides from any laboratory that I was managing commented on the excellent quality of both H&E and special stains. This is excellence and consistency: for almost 40 years.

Our organization has benefitted immensely from our partnership with Poly Scientific. We use many of their products in our high-volume histology operation and can attest to their excellent quality. Their chemicals and stains play a critical role in our ability to offer a wide spectrum of histopathological staining; our technologists recognize the convenience that these products bring to our laboratory and our pathologists appreciate the resulting quality and low turn-around times of our tests. They offer incredible customer service, which is especially evident in their ability to customize the specifications of their products to suit the needs of our laboratory. Delio, their chemist, has provided us with custom solutions that have improved the breadth and consistency of our testing.

I have known the rep, Gary Beck from Poly Scientific for 10 years. It is a pleasure to work with Gary and Poly Scientific. Their products are excellent and give the best results. When I need a product right away, Gary would hand deliver it to me. When I have a question about my reagents, Delio, the chemist, answers my question. When I needed a special order made to the product, they accommodated me. Poly Scientific values their customers. I have enjoyed and will continue to enjoy working with them.

Clearly, the owners and employees at Poly Scientific R&D take pride in their work and have a mandate for quality reagents that is unmatched by any other vendor. In addition, the Poly Scientific R&D customer service team has been responsive to any request: custom reagents by Delio, overnight shipping by Lizzie. With today’s expectations of providing top patient care quality in a short turnaround time, I highly recommend using Poly Scientific reagents and products. They will provide excellent, consistent results, which will also help your laboratory to run more efficiently.
