This is a standard model of manual cryogenic plunge freezer for the preparation of vitrified biological and material science samples for cryogenic electron microscopy studies. In this standard model, the specifications are as follows. The plunger itself has a base footprint of 12" by 12" with a height of 18". The entire weight is a little over 10lbs. The base and most of the parts are made out of aluminum, whereas the trigger bar is made out of brass.
