Tissue-Tek VIP® Fixative

Eliminate your warm water flush with one fixative

Tissue-Tek VIP® Fixative provides an alternative to the standard neutral buffered formalin, and can be used with all tissue processors.

with Neutra-pHase™

Eliminate the need for the routine warm water flush with the Tissue-Tek VIP® Fixative. Using the unique Neutra-pHase™ technology, the Tissue-Tek VIP® Fixative produces no precipitates in the presence of alcohol, contrary to all other 10% neutral buffered formalin (NBF) products. The Tissue-Tek VIP® Fixative will not promote formation of salts within the tissue processor lines, which can cause costly damage to any brand of tissue processors unless regular maintenance is performed. Since the base ingredient is formalin, it is fully compatible and can replace 10% NBF without any adjustments to your procedures.

Tissue-Tek VIP® Fixative is designed with ionic strength to enhance cellular staining qualities in some procedures. It improves cell wall rigidity, resulting in firmer cutting and better results.

The product is offered in three convenient package sizes: 1 gallon, 2.5 gallons, and 5 gallons.
