CryoMill

The CryoMill is tailored for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. Thus 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 -196 ° C. Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes the operation very safe. Its versatility ( cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml. Application Examples animal feed, bones, chemical products, food, hair, oil seeds, paper, plant materials, plastics, sewage sludge, soils, tablets, textiles, tissue, waste samples, wood, wool, ... Product Advantages powerful cryogenic grinding by impact and friction, up to 30 Hz 3 different grinding modes ( cryogenic, dry or wet at ambient temperature) closed LN2-system ( autofill) for enhanced safety, avoids any contact of the user with LN2 screw-top grinding jars for convenient, leak-proof operation wide range of accessories including various LN2 feeding systems, jar and ball sizes, adapter racks, materials low LN2-consumption clearly structured user interface, memory for 9 SOPs programmable cooling and grinding cycles ( 10 s to 99 min) Features Applications size reduction, mixing, homogenization, cell disruption Field of application agriculture, biology, chemistry / plastics, construction materials, engineering / electronics, environment / recycling, food, geology / metallurgy, glass / ceramics, medicine / pharmaceuticals Feed material hard, medium-hard, soft, brittle, elastic, fibrous Size reduction principle impact, friction Material feed size* d 8 mm Final fineness* ~ 5 µ m Batch size / feed quantity* max. 20 ml No. of grinding stations 1 Setting of vibrational frequency digital, 5 - 30 Hz ( 300 - 1800 min-1) Typical mean grinding time 10 min / 4 min ( cooling / grinding) Dry grinding yes Wet grinding yes Cryogenic grinding yes Cell disruption with reaction vials yes Self-centering clamping device yes Type of grinding jars screw top design Material of grinding tools hardened steel, stainless steel, zirconium oxide, PTFE Grinding jar sizes 5 ml / 10ml / 25 ml / 35 ml / 50 ml Autofill 10 l / 50 l Setting of grinding time digital, 10 s - 99 min Storable SOPs 9 Electrical supply data 100-240 V, 50/ 60 Hz Power connection 1-phase Protection code IP 30 Power consumption 260 W W x H x D closed 385 x 370 x 675 mm Net weight ~ 40 kg
