6775 freezer/mill174 a small cryogenic mill with an integrated liquid nitrogen reservoir and insulated housing that processes samples between 0.1 5 grams.it is specifically designed for cryogenic grinding and pulverization of tough and/or temperature sensitive samples in a sealed vial that remains submerged in liquid nitrogen.
very often this mill series is used for cryogenic grinding. operational advantages. the material fineness is extremely accurate due to the high rotating speed of the disc. the spacious grinding chamber prevents any internal particle coating or a mill blockade when grinding material containing oil or grease or of tendency to stick.
what is cryogenic grinding cryogenic grinding involves the use of liquid nitrogen to chill pellets in advance of the grinding process. once cooled the pellets proceed through a mechanical mill. the use of liquid nitrogen to chill the pellets enables more effective size reduction.
cryogenic grinding of plant and animal tissue is a technique used by microbiologists. samples that require extraction of nucleic acids must be kept at 80 176c or lower during the entire extraction process. for samples that are soft or flexible at room temperature cryogenic grinding may be the only viable technique for processing samples.
cryogenic milling with the pin mill gsm 250 . the pin mill gsm 250 is a cryogenic grinding system of the highest quality. the milling plant is made of stainless steel. this also applies to the other system periphery such as the cooling screw conveyor the filter etc.
the autofill system avoids direct contact with ln 2 and makes cryogenic grinding very safe. its versatility (cryogenic wet and dry grinding at room temperature) makes the cryomill the ideal grinder for quantities up to 20 ml. you may also be interested in the high energy ball mill emax an entirely new type of mill for high energy input. the
a pin mill or grinder was employed for grinding the black pepper under ambient and cryogenic conditions. the mill was obtained from hosakowa alpine (germany) with a grinding capacity of 80 kg hr 1 and it was run by a three phase 3.7 kw motor. it consisted of two rotors (one stationary while the other was rotating) with a number of cylindrical stainless steel pins of 4 mm diameter affixed on
if not impossible to grind using traditional methods. cryogenic grinding in the spex . sampleprep freezer/mill174 is the easiest way to homogenize these materials. using cryogenic grinding to chill samples until they are brittle and then break them up through impact crushing or shearing allows the toughest samples to be ground.
