The M-T Vial File® provides a compact, easily accessible means of sample storage and has been a popular item for Wheaton. As a result, two new M-T Vial Files® have been created which allows users to store either 8 or 20 mL vials in a similar fashion. The clear polystyrene case has a hinged lid that allows the vials to be covered and protected. The partitions are designed to provide extra protection for the vials. The alpha numerical indexing card allows for identifi cation of each sample vial. The M-T Vial File® comes with polystyrene case, partitions, and indexing card. Partitions and index cards can also be purchased separately.
