F.W. 161.40 B.P. 126.7°C. For fast preparation of soft insect tissues, also bacteria and some other "hardy" specimens in lieu of CPD.
Method: After complete dehydration up to 2 changes in abs. ethanol, treat specimens for 10min. in 1:1 ethanol : HMDS and then 3x10 minutes in pure HMDS. Dry specimen on filter paper in a glass Petri dish with lid ajar within a fume hood.
