New Retsch freezer mill from Wolflabs

Product Update

Introduction
New CryoMill freezer mill from Retsch has been added. Thermally sensitive and elastic substances are successfully processed by cooling with liquid nitrogen. The CryoMill was specifically designed for cryogenic grinding. 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.

Features and benefits
- Fast, efficient cryogenic grinding at -196 °C
- Ideal for plastics, temperature-sensitive materials and samples with volatile components
- Particularly safe due to autofill system for liquid nitrogen
- Automatic pre-cooling of sample and grinding jar for optimum results
- Programmable cooling and grinding cycles
- Highly reproducible grinding results
- Low consumption of liquid nitrogen
- Grinding jar materials include PTFE, stainless steel, hardened steel or zirconium oxide
- Memory for 9 Standard Operating Procedures (SOP)
- Suitable for dry and wet grinding
