Benz Microscope Negative Stain Kit with 2 forms of Nigrosin Solution. Negative staining method stains the background of your bacterial sample while leaving the actual bacterial cells untouched; allowing the cells to be quite visible on a dark background. Negative staining does not require the bacterial cells to be heat-fixed and is especially useful for cells that are susceptible to damage during the heat fixation process, such as cryptococcus neoformans. Often used to determine cell size, shape, arrangement. 

This is a Benz Microscope Custom Kit, which includes both, Nigrosin 0.5% Aqueous Solution and Formalin-Nigrosin, along with Bibulous Paper in the set. Depending on your desired observations, you can easily choose which Nigrosin Solution to use for your specimen. The Aqueous Solution will not kill or alter the shape of bacteria cells, while Formalin-Nigrosin can kill dangerous bacteria, with very little, to no, distortion. SKU  BZ0055 MPN NN0055-PK
