If, however, longer grinding times are required, it is also possible to pre-select periods of intermediate cooling and the number of cryogenic cycles. All instrument parameters are retained during standby operation for subsequent processes.

Grinding of leaves for extraction of nucleic acids

The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low. Preventing sample warming can be done be adding additional liquid nitrogen to the mortar while pulverizing the sample.
