Acetone can be used for hardening and dehydrating tissues. It can also be used for the extraction of various principles from animal and plant substances.

Buffer for fixatives for light and electron microscopy; e.g., osmium tetroxide, formaldehyde, glutaraldehyde, Karnovsky’s fixative.

For Light and Electron Microscopy. This popular methanol-free fixative is a formaldehyde-based material formulated to eliminate the need to select a fixative for tissue based on the type of microscopy to be employed.

Polysciences was the first to develop a superior grade of glutaraldehyde suitable for immunochemical techniques. Each batch of vacuum distilled glutaraldehyde manufactured by Polysciences is analyzed to maintain consistent high quality and freedom from contaminants which destroy antigenicity. Each ampoule is fitted with an ampoule cracker for added safety.

Used for various research needs. It is ideal for use as a fixative for frozen tissue sections for histology. EM grade quality.

Used in place of critical point drying for preparation of soft tissues for SEM observation. Procedure takes 5 minutes as compared to 90 minutes for critical point drying.

A biologically stable buffer system for osmium tetroxide and other EM fixatives. Provides better stability and buffering capacity than traditional veronal acetate buffers.

Methanol, 99.5%, EM Grade.
