Retsch has launched the Cryogirl Cryomill, a system that has been specifically designed for cryogenic grinding applications.
The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process.
Therefore the sample is embrittled and volatile components are preserved.
The liquid nitrogen circulates through the system and is continually replenished from an autofill system in the exact amount, which is required to keep the temperature at -196C.
The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.
This results in reduced consumption and guarantees reproducible grinding results.
The Cryomill is ideal for plastics, temperature-sensitive materials and samples with volatile components.
It is said to be safe and convenient thanks to an integrated cooling system with autofill; programmable cooling cycles, digital parameter settings; high final fineness down to approximately five microns.
