Retsch Grindomix GM 300 knife mill for cryogenic grinding

Friday, 21 February, 2014 | Supplied by: LabFriend


The Retsch Grindomix knife mill can be used for the rapid and reproducible size reduction and homogenisation of dry as well as moist, oily or fatty sample materials. For samples containing volatile or degradable substances, grinding with dry ice is recommended. This way the sample is embrittled and the volatile components, which are frequently the object of the analysis, are preserved.

The knife mill can be used in food labs for sample homogenisation. To optimise processing under dry ice, or after previous external cooling of the sample with liquid nitrogen, Retsch offers special accessories for cryogenic applications. A full metal knife of stainless steel, a grinding container of stainless steel and a special lid for dry ice application, containing a small aperture for the escape of overpressure, are a suitable combination for cryogenic sample preparation.

The Grindomix GM 300 is suited to process up to 4500 mL sample material and provides representative grinding results within seconds. A wide selection of accessories makes the product a versatile tool for sample homogenisation. To grind smaller sample volumes up to 700 mL, Retsch offers the Grindomix GM 200, which can also be used for dry ice applications.
