Frozen Grinding Machine(Semi-Automatic Liquid Nitrogen Freezing) JXFSTPRP-II-02Comprehensive real-time ultra-low temperature freezing grinding/pulverizing samples, rapidly and thoroughly粉碎 samples at -196℃ conditions, shortening the grinding time while ensuring the sample's properties remain unchanged. Recognized as the "ultimate grinding method," it is widely used in fields such as biochemical, zoological and botanical, medical, mineralogy, materials science, architecture, forensic science, and drug detection.
Liquid Nitrogen MillApplication Scope:
The product is suitable for heat-sensitive materials such as Chinese and Western medicines, animals and plants, rubber, plastics, (roots, stems, leaves, flowers, fruits, seeds, brain, heart, lungs, stomach, liver, thymus, kidneys, intestines, lymph nodes, muscles, bones, fungi, bacteria, food, pharmaceuticals, coal, oil shale, wax products, PE, PS, textiles, and resins), as well as substances that exhibit toughness at room temperature and cannot be crushed.
Operation Steps:
(1) Submerge the adapter and grinding jar into the liquid nitrogen sample, rapidly cooling it to -196 degrees. Prevent sample degradation or induce a change in the physical properties of the sample.
(2) Add liquid nitrogen to the liquid nitrogen tank inside the cavity, utilizing the cooling effect of liquid nitrogen to lower the cavity temperature to a low level, thereby ensuring the entire grinding process remains at a low temperature state.
(3) Place the adapter and grinding drum into the grinder. Secure the safety cover and lock the safety latch before operation.
Key Technical Features:
High accuracy and reproducibility of data
During the grinding process, the sample is always kept at an ultra-low temperature induced by liquid nitrogen.
2.1 minutes for the sample to cool to -100°C, 4 minutes and 30 seconds to reach -196°C
3. Samples remain fully enclosed during the crushing process, ensuring the integrity of the sample is preserved within the grinding tube, and maintaining control over hazardous and critical samples.
4. Sample bottles are individually sealed, making it extremely convenient to clean after each breakage, thus preventing cross-contamination between samples and external contamination.
B. Multi-functionality, user-friendly design
LCD display, capable of setting parameters such as grinding time and grinding operating frequency (optional)
2. Optional Portable Control Panel
3. Stores up to 20 programs (optional)
4. Available in 1.5ml, 2ml, 5ml, 10ml, 25ml, and 50ml sample tubes for sample grinding
C. Durability
Just one moving part—the collider—greatly reduces mechanical stress, extending the equipment's lifespan.
2. Robust Technical Support: Shanghai Jingxin Co., Ltd. boasts over 2,000 users and specializes in the production of professional sample pretreatment equipment.
