The HMD-400 Multifunction CryoGrinder is a specially designed equipment for fine grinding and fine grinding of hard, medium-hard and brittle samples in the laboratory. Samples include grains, oilseeds, soil, tobacco, wood, animal feed, cheese, fruits, bones, hair, plant and animal tissues, fertilizers, electronic waste, sludge, alloys, coal, ores, chemicals, plastics, ceramics, glass, DNA extraction, and more.
● Large-screen touch screen operation display, simple operation and easy to understand operation; Equipped with memory function, it can store a variety of operating procedures;
● Intelligent control, grinding time can be controlled, time and speed can also be set and displayed;
● Highly reproducible grinding results;
● Fast grinding and homogenization, short grinding time, large capacity for rapid sample preparation for XRF analysis;
● Double-pot grinding, and can provide high-throughput grinding for biological samples;
● A variety of different materials and volume grinding jars are available, with a wide range of applications, lossless wet grinding, and screw-tightened and sealed grinding jar design;
● Comfortable low-temperature grinding, which can be used for heat-sensitive materials without long-term freezing process, with very little liquid nitrogen consumption;
● Breaking the wall of animal and plant cells or breaking the cells of the suspension, more than 10 samples can be processed at a time;
● Low-temperature grinding can prevent molecular degradation due to pressure and heat;
● For most materials, it only takes tens of seconds to achieve the purpose of grinding, mixing and homogenizing the sample.
