Columbia Jar and Cap

These staining jars hold up to 4 cover slips 17-23 mm wide, and up to 30 mm long. Longer cover slips can be accommodated if the cap is removed. The jar includes a 43-400 white polypropylene screw cap with a PTFE coated polyethylene liner. Made from soda-lime glass, the jar is chemical resistant. In addition to staining applications, Columbia Jars can be used for cleaning cover slips, as well as coating them with materials such as poly-lysine or silane.
