Hexamethyldisilazane (HMDS) 100ml

HMDS, [(CH₃)₃Si]₂NH, can be used in place of critical point drying for the preparation of soft tissue for SEM examination, for example, of delicate insect tissues.

It is faster, preserves surface detail, reduces thermal and pressure stresses, and may also reduce the extraction of cellular components compared with CPD. HMDS can be used to dry specimens such as bacteria on polycarbonate filters. 100ml
