Crystlizatn App Craig 7ML

CRAIG TUBES
A combination crystallizing and filtration centrifuge tube. Filtered solutions are allowed to cool in the Craig tube, inducing crystallization.


• Two are required to balance in a centrifuge
• Manufactured from 33 expansion, low extractable borosilicate glass conforming to USP Type I and ASTM E438, Type I, Class A requirements

The Craig stopper is placed in the tube neck and the whole apparatus is inverted into a test or centrifuge tube. Centrifuging forms a mat of crystals between the stopper and the walls of the Craig tube and draws away excess solvent. Further washing and crystallization steps are possible.
