General description

Formalin solution (10%, neutral buffered) is a widely used fixative for samples processed for light microscopy. It requires a relatively short period of fixation. It is suitable for the long-term storage of tissue. Once properly fixed, the tissue should be able to withstand the subsequent stages of tissue processing or staining.

Application

Formalin solution (neutral buffered, 10%) has been popularly used as a general-purpose histological fixative to fix tissue samples.
Popular general purpose histological fixative.

Packaging

Case containers are polypropylene with white leak-proof lids and are partially prefilled with 10% NBF.
