Colleges, Universities, museums, research laboratories, anywhere specimens need to be immersed in a preservative solution are using our Specimen Tags. They are manufactured using a chemically pure cellulose material, which contains no resins or bonding agents. The most common use for a Specimen Tag is to mark samples that are sealed in formaldehyde. TLS can customize this product with your organizations name, numbering sequence and punched holes for attachment to your specimen.
