LM 200 CryoGrinder
The LM200 CryoGrinder chills samples in liquid nitrogen and pulverizes them with a magnetically driven impactor. The sample becomes brittle and the volatile components are preserved under the low temperature, so that a good grinding effect can be achieved.
The automatic control function of liquid nitrogen content avoids the contact and danger of manual operation. CryoGrinder LM200 can also be used in dry grinding at normal temperature.
Application
It is applied to samples with strong toughness and thermal sensitivity that are difficult to be ground and crushed at room temperature, such as rubber, plastic, food, mineral, animal and plant tissue analysis, drug, biochemical DNA detection, cell disruption and other fields.
Typical Sample Types
Polymers, rubber, textile materials, grain particles, hair, nails, skin, bones, muscle tissue, etc.
Features and Advantages
- Electromagnetic vibration impact guarantees fast grinding speed, high precision, good uniformity and repeatability;
- The liquid nitrogen automatic filling system automatically supplement the liquid nitrogen consumed in the process of sample freezing and grinding to ensure the stability and safety;
- Industrial touch screen control panel, impact frequency, pre-cooling time, impact grinding time, cycle grinding times can be set, easy to operate and reliable;
- Safety design: when the cover of the instrument is open, the instrument cannot be started; Only when the instrument cover is closed and locked can the instrument be started;
- Streamlined and ergonomic design, simple and convenient operation;
- When the liquid nitrogen level is lower than the set value, the liquid sensor will alarm and automatically replenish the liquid nitrogen; and the instrument stops running to protect the electromagnetic coil from damage.
