Description
Device for grinding in liquid nitrogen is a cryogenic accessory that enables size reduction of soft, slightly fatty or moist materials that are otherwise difficult to mill at ambient temperature. The grinding set is placed inside an insulated cryo-box; addition of liquid nitrogen embrittles the sample so that even challenging specimens, such as soft PVC film pieces, can be brought to analytical fineness. Strong thermal insulation of the cryo-box keeps coolant consumption low during operation. For cryogenic milling, mortars and grinding balls made of stainless steel, hardened steel or tungsten-carbide hard metal are recommended. This accessory from manufacturer Fritsch is designed for use with compatible vibratory and rapid mills in laboratory sample-preparation workflows. Supplied as a single unit with a net weight of 2,6 kg, it expands the application range of existing mill systems to temperature-sensitive or tough organic matrices. Laboratories performing elemental or compositional analysis of polymers, biological tissues and similar soft materials benefit from the controlled embrittlement and efficient cooling provided by this liquid-nitrogen grinding device.

Questions about deep-temperature milling device (cryo-box)
What is this article?
deep-temperature milling device (cryo-box) is the article on this page. Luminix Health distributes Fritsch for laboratory use. It sits in Mills, grinders & homogenisers, inside Test sieves & mills, in Lab instruments.
A mill, grinder or homogeniser reduces particle size or breaks a tissue before an extraction. The rotor and the sieve insert decide the result. A knife mill and a bead mill are different machines. The sample has to tolerate the heat the motor puts into it.
A test sieve sorts particles by whether they pass an opening. Wire mesh and perforated plate are two ways of making that opening, and the nominal size is not a suggestion. A sieve shaker repeats the motion so the result does not depend on how hard someone shook by hand. A mill or grinder makes the particles smaller before they are sieved. The certificate of the sieve, and the opening size, are what an audit asks for. Measurement practice around mass and dimension sits with the BIPM, EURAMET and BELAC.
Which category should I open next?
