CryoMill
Product Overview
Cryogenic grinding is a process where thermally sensitive and elastic substances are successfully processed by cooling with liquid nitrogen. The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved. The liquid nitrogen is continually supplied from an autofill system in the exact amount required to keep the temperature at 196 C. The user never comes into direct contact with LN2 which ensures a high degree of operational safety. The CryoMill's versatility (cryogenic, but also wet and dry grinding at room temperature) makes it the ideal grinder for sample quantities up to 20 ml. Powerful impact ball milling results in highest grinding efficiency.
UNMATCHED PERFORMANCE FOR CRYOGENIC BALL MILLING
- Max. speed 30 Hz
- Horizontal oscillation causes strong impact effects for effective sample processing
- Up to 8 mm feed size and 5 m final fineness
- 1 grinding station for jars of min. 5 ml and max. 50 ml, adapter for 6 x 2 ml tubes
- Jars are continuously cooled with liquid nitrogen during processing, safe handling thanks to autofill tank
- Small bench top model
- Storable SOPs and cycle programs, compact bench top model, 4 different jar materials for dry and wet grinding
FUNCTIONAL PRINCIPLE
- The grinding jar of the CryoMill performs radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the jar and pulverize it.
- The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the cryogenic grinding process.
