Automatic Plunge Freezing

The EM GP2 plunger is a safe and accurate system that allows for reproducible results, in a temperature and humidity controlled and protected environment.

The instrument is designed to freeze fluid or extremely thin samples spread on an electron microscopy grid, into liquid ethane (after removing excess fluid by automatic blotting).
