The Vitrobot is an automated device for vitrification (plunge freezing) of aqueous samples.
Conventional TEM requires high vacuum inside the microscope column, therefore all samples need to be dried out before observation. Cryo-TEM is a good alternative for the direct observation of liquid samples in its original state: specimens are vitrified in liquid ethane or propane and analyzed in the microscope at low temperature. The vitrification method is based in a very fast sample cooling that prevents the formation of crystalline ice. Moreover, the thin layer of amorphous ice formed during the vitrification process protects the material from electron beam damage.
The Vitrobot Mark IV provides precise but flexible control of all critical parameters in the plunge-freezing process.
The new Vitrobot Mark IV is an unit that offers great value to the demanding scientific areas of cell biology and molecular imaging as well as being very suitable for food, industrial, pharmaceutical and nanotechnological applications. Fundamental research in cellular and structural biology is increasingly focused
