Vertical freezing grinder
The multi-channel vertical freezing grinding instrument is an efficient sample grinding device that can handle multiple samples simultaneously. It is widely used in both scientific research and industrial fields.
Working principle:
The multi-channel vertical freezing grinding instrument usually operates in a vertical vibration mode. It uses a motor to drive the grinding platform to perform high-frequency reciprocating movements in three dimensions (up and down, left and right). Under this motion, the grinding beads in the grinding jar exert high-frequency impacts, shearing, and friction on the sample, thereby grinding the sample into fine particles. At the same time, the instrument is equipped with a built-in refrigeration system, which can lower the sample temperature to a low level, causing the tough or heat-sensitive samples to become brittle and facilitating the grinding process.
Technical features:
- High-throughput processing: It can handle multiple samples simultaneously, significantly enhancing work efficiency.
- Low-temperature protection: The refrigeration range is generally from -50℃ to room temperature, with high temperature control accuracy.
- Intelligent operation: Equipped with a touch screen, it supports presetting multiple grinding formulas, allowing users to store ≥30 sets of experimental data. They can call the corresponding mode based on the sample type and perform multi-stage programming to reduce interference from human factors.
- Safe and reliable: It uses an electric door switch and electromagnetic locking device to ensure the safety of samples during the grinding process and avoid cross-contamination.
- Highly versatile: It can be compatible with various specifications of grinding jars and grinding beads, capable of handling samples of various types such as plant tissues, animal tissues, fungi and bacteria, plastics, polymers, etc.
