BUTVAR B-98

polyvinyl butyl resin for the preparation of superior, thin grid support films

BUTVAR B-98 support films are mechanically stable, electron-transparent, and have minimum intrinsic structure. Their hydrophilic nature facilitates the spreading of the sections allowing even staining on the surface. This film can resist an intense electron beam during focusing and photography at high magnifications, or with the beam at cross-over. The mechanical stability is appreciated when mounting freeze- fractured replicas or serial sections, especially when slotted grids are used.
