Overview
HMD-400 Multifunctional Freeze Grinding Instrument is a fine grinding and fine grinding equipment specially designed for laboratory processing of hard, medium hard and brittle samples. It is suitable for cereals, oil seeds, soil, Tobacco, wood, animal feed, cheese, fruit, bone, hair, plant and animal tissue, fertilizer, electronic waste, sludge, alloy, coal, ore, chemicals, plastics, ceramics, Glass, DNA extraction and other samples.
Features
1. Adopt large-screen Touchscreen operation display, the operation settings are simple and easy to understand, and there is a memory function to store a variety of operation programs.
2. Intelligent control, grinding time controllable, time and speed can be set and displayed.
3. The ground results have high repeatability.
4. Fast grinding and homogenization, short grinding time, and large rapid sample prepative Processing capacity for XRF analysis.
5. Dual tank grinding, and can provide high-throughput grinding for biological samples.
6. A variety of different materials, volume grinding tank to choose from, a wide range of applications, no loss of wet grinding, can be tightened, sealing type grinding tank design.
7. Comfortable low temperature grinding, can be used for heat sensitive materials without long-term freezing process, and the consumption of liquid nitrogen is very small.
8. Animal and plant cell tissue crushing or suspension cells can handle more than 10 samples at a time.
9. Low temperature grinding prevents molecular degradation due to pressure and heat.
10. For most materials, it only takes tens of seconds to grind, mix and homogenize the sample.
Principle
The equipment is ground by vibration mode, the vibration speed range is 60-1800r/min, Frequency is 1-30Hz, combined with a variety of grinding tanks and adapters, dry grinding, wet grinding, low temperature grinding and high throughput grinding, rapid sample fine pulverization to 5~ 10μm particle size.
Applications
Grains, Soil, Cheese, Ceramics, Plastics, Wood, Tobacco, Fruits
Steps
1. Select the appropriate grinding tank or adapter according to the sample.
2. Set the grinding time (1s-99min59s) and vibration speed (60-1800r/min).
3. Start the device to grind.
4. Remove the sample after finishing grinding.
Notice
• Ensure that the sample feed size does not exceed 8mm.
• Select the appropriate grinding method according to the Sample type (dry grinding, wet grinding, low temperature grinding or high flux grinding).
• Make sure to tighten when using the sealing grinding tank to prevent sample leakage.
• Pay attention to the safety of liquid nitrogen when grinding at low temperature and avoid long-term freezing process.
• Regularly check the operating status of the equipment to ensure the repeatability of the grinding results.
