glass knife
glass knife
A glass knife is a blade for a microtome. The knife is a fabricated sharp edge line of a glass made by fracturing a thick glass or a glass rod. The glass knife is used to make an exposed specimen surface flat prior to ultrathin sectioning using a diamond knife, or to perform trimming of the resin of a resin embedded specimen.
Precautions for use; When the knife is applied to hard materials or the same position of the blade is repeatedly used, the blade tends to spill and can damage the surface of a specimen. Thus, the knife needs to be used while changing the position of the blade.
