High Pressure Vitreous Freezer
The School of Physics and Astronomy has a requirement for a ‘High Pressure Vitreous Freezer’ (HPVF); this is a device that freezes samples to extreme low temperature at an exceptionally high rate to essentially ‘freeze a sample in time’. If a sample is cooled at a slower rate ice may form within/on fragile samples (for example cells), which would swell/crystalise and destroy the nano/microstructure of the sample. Freezing at an exceptionally high rate freezes the sample faster than ice can form, avoiding this issue...
