For vitrification of samples in solution both an instrument from FEI (Vitrobot) and from the company Gatan () are available. To achieve the best possible result, the preparation conditions can be precisely adjusted due to the air chamber before the freezing process. Automating the process provides good reproducible results. In the case of Gatan cryo plungers, it is also possible to adjust the gas composition in the sample chamber.
