The Cryogenic Grinding Mill chills and pulverize samples to liquid nitrogen temperatures. The sample vial (0.5 - 4ml capacity) is immersed in liquid nitrogen
throughout the grinding cycle. The sample is stabilized at cryogenic temperatures and its
key characteristics preserved.
50ml sample capacity vials are available for use with the larger cryogenic mill. Other
features provide for speed control (2 - 30 impacts/second) and programmable grinding
duration (0.1 - 100 minutes).
The Standard Cryogenic Mill offers a touch-screen interface, a removable control panel and on-board self diagnostics. It is self-contained with a liquid nitrogen tub, insulated case, digital speed control, programmable
timer and grinding vial set which includes 4 transparent polycarbonate cylinders (4ml capacity), 2 stainless steel end caps, one stainless steel impactor, an extractor/vial opener and vial rack. The mill measures 12" x 12.5" x 9" and weighs 12lbs. Stainless steel cylinders are optional.
The Expanded Cryogenic Mill is also self-contained with a liquid nitrogen tub, liquid nitrogen level sensor, insulated case, digital speed
control, programmable timer and grinding vial set which includes 4 transparent
polycarbonate cylinders (50ml capacity), 2 stainless steel end caps, one stainless steel
impactor, an extractor/vial opener and vial rack. The mill measures 15.25" x 22" x 18.25"
and weighs 53lbs. A multi-vial adapter is optional when multi-vial grinding is preferred.
The adapter will accommodate 4 transparent polycarbonate cylinders.
115V, 230V and CE models are available. Please specify and inquire for current pricing.
The Cryogenic Grinding Mill maintains a vital role for biological
discovery, pharmaceutical analysis, drug testing, medical research,
forensic science and many other analytical investigations. Cryogenic
grinding prepares any biological material for nucleic acid extraction
without damaging the RNA or DNA. Skeletal material including human
bones and teeth can be ground cryogenically and DNA extracted from
the powder, whether the remains are recent or very old. Plant and
animal tissue of all types is easily ground and the resultant sample
material can be subjected to classical methods of RNA extraction and
analysis. The complex molecules present in drugs such as isomers
and their metabolites are critical to both pharmaceutical researchers
and crime labs. Among endless possibilities in the medical field, many
cases have pulverized fresh bone and used the growth matter to
stimulate the formation of bone around prosthetic implants. Contact
