Signature Series Flex is a patented dehydrating reagent specifically designed for processing and staining of histological and cytological tissue specimens. Flex is a clear, colorless blend of isopropyl and methyl alcohol. It is a non-controlled substance and does not require record keeping. Flex is available in concentrations of 80%, 95% and 100%. It is readily miscible with water to form any desired grade of alcohol. Flex is miscible with all clearing reagents. Studies have indicated that Flex does not over-dehydrate small tissue specimens as rapidly as ethyl and isopropyl alcohol, when used in accordance with the processing guidelines developed for Flex. The absence of over-dehydration during tissue processing allows for consistent results with both large and small tissue specimens. Flex can be used in tissue processing, staining and as a dye or stain solvent in place of ethyl alcohol. Flex can be used in all special stains that require dehydration in ethyl alcohol and in immunohistochemical reactions that are compatible with alcoholic dehydrants. Flex has been proven to produce brilliant hematoxylin and eosin stains, with crisp nuclear detail when used within designated guidelines. Flex is compatible with both open and closed tissue processors. Flex is a flammable product and must be stored in a flammable fire cabinet.
A reagent grade alcohol solution (e.g., methanol, ethanol, isopropanol) intended to be used as a dehydrant in the processing of biological tissues or clinical specimens.
