<p>A system (10) for preparing specimens in a controlled environment to insure that a liquid or partially liquid specimen is maintained in its original state while it is being prepared, and once prepared the specimen is vitrified or solidified with minimal alteration of its microstructure. The controlled environment is provided within a chamber (20) where humidity and temperature can be controlled precisely while the specimen is prepared. The specimen is mounted on a plunger (22) and a shutter controlled opening (46) is opened substantially simultaneously with release of the plunger (22) so the specimen is propelled through the shutter (46) into an adjacent cryogenic bath (82).</p> |
