A note on the use of the word “Certified”. 

Some vendors of dyes use the term “Certified” when in fact the dyes were not tested and certified by the Biological Stain Commission. Please be aware that such dyes may or may not be suitable for biological staining, and the word ‘Certified’ is in no way is connected to the Biological Stain Commission or its certification process. Some products that have not been tested and approved by the BSC are claimed by their vendors to “meet the standards of the Biological Stain Commission“.  

When purchasing dyes for biological use, specify that they must be “Certified by the Biological Stain Commission”.  Caveat emptor!  Every bottle containing dye powder from a batch certified by the BSC has a distinctive label, supplied by the Commission, with numbers that identify the batch and the test results, and allow tracing of materials sold among companies.  Click here for more about recognizing genuine BSC-certified stains.
