The LPM-01 cryogenic mill with closed liquid nitrogen (LN2) auto-fill system is carefully developed by RUISHENBAO? analytical (shanghai) Co., Ltd, which pulverize and mix some soft, temperature-sensitive or high fat content of samples such as candy, chocolate, Soybeans, peanuts and other food samples for sample preparation in laboratory. The grinding jar is continually cooled with liquid nitrogen from the integrated LN2 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 auto-fill system in the exact amount which is required to keep the low temperature of user that evenly reach -196 ¡ãC depending on the continuously filling time and amount of LN2. Powerful impact vibratory disc mill results in a perfect grinding efficiency. The auto-fill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the LPM-01 the ideal mill for quantities up to 100-500 mL (depend on feed material). Its typical area of application includes food analysis, plastic product analysis, mineral analysis, medical aid analysis, drug performance testing, and identification of textile components and so on. Advantage

? Powerful cryogenic grinding by impact and friction from vibratory disc mill, up to 700-1400rpm, continuously adjustable, short grinding time;

? 3 different grinding modes (cryogenic, dry or wet at ambient temperature);

? Closed LN₂ auto-fill system for enhanced safety, avoids any contact of the user with LN₂;

? Low LN₂-consumption;

? Clearly structured user interface, one-touch operation, easy controlling,;

? Touch-screen programmable controls for cooling and grinding cycles;

? High-capacity grinding up to 500mL of hard, medium-hard, soft, brittle, elastic or fibrous samples (max. equivalent of 500g, depend on feed material);

? Pneumatic grinding-jar clamping (with air-pressure) for convenient and safe handling: mill only starts if the grinding-jar clamping is correct;

? Noise-insulated grinding chamber and especially safe hood locking;
