With the advancement of science and technology, DNA detection, polymer analysis, and biological sample research have become central in the world of research and development. When it is essential to preserve the integrity of sensitive biological components in samples, innovative technologies like the CryoGrinder LAM-200 provide an efficient and reliable solution
Working Principle of LAM-200
The Munro's CryoGrinder operates on advanced electromagnetic vibration technology. The sample, along with a metal impactor, is placed inside a specialized grinding jar, which is tightly sealed and inserted into an electromagnetic vibration coil. The grinding jar is immersed in liquid nitrogen at a temperature of -196°C for pre-cooling. After freezing, the impactor is activated in a horizontal motion, grinding the sample with precision while maintaining its brittleness and preserving volatile and sensitive components.
Key Benefits of the LAM-200
The Cryomill Laboratory Ball Mill offers significant advantages, making it a vital instrument for laboratories, biological industries, and chemical and medical fields:
- ●High Precision and Repeatability: Based on electromagnetic vibration impact, the device ensures high-speed grinding with superior accuracy, uniformity, and consistency.
- ●Automatic Liquid Nitrogen Filling System: Automatically replenishes liquid nitrogen during the grinding process, ensuring stability and safety.
- ●Industrial Touch Screen Control Panel: Allows full control over grinding frequency, pre-cooling time, and grinding cycles, offering ease of use and reliability.
- ●Safety Design: The device does not operate unless the lid is fully closed and locked, ensuring safe operation.
- ●Smart Warning System: A dedicated sensor alerts when the liquid nitrogen level is low and automatically refills it, preventing damage to the system.
- ●Ergonomic Design: Streamlined for simple and convenient operation.
