Fully automatic freeze grinder

With the rapid development of technology, biochemical DNA testing and polymer analysis testing are becoming increasingly important. In order to maintain the various components and biological information of the sample, low-temperature crushing has become a necessary choice.Fully automatic freeze grinderLM400 keeps the sample at a low temperature of -196 ℃, making it brittle and preventing the volatilization of volatile substances in the sample. The structure and composition information of the sample are effectively preserved, thus achieving good grinding effect.

*The electromagnetic impact force ensures the effectiveness of grinding, while the automatic control function of liquid nitrogen quantity avoids the contact and danger of manual operation, making it an ideal instrument for processing thermosensitive samples and biochemical DNA/RNA detection of various sample grinding.

Product Application

○ Application Fields
Applied to samples with strong toughness and thermal sensitivity that are difficult to grind and pulverize at room temperature, such as rubber composition analysis, plastic composition analysis, food composition analysis, mineral composition analysis, animal and plant tissue analysis, drug composition analysis, biochemical DNA detection, cell wall breaking pulverization, and other fields.

○ Typical samples
Suitable samples include polymers, rubber, textile materials, grain particles, hair, nails, skin, bones, muscle tissue, etc.

working principle

The sample is ground and crushed using electromagnetic oscillation impact. The sample and metal impact column are loaded into a grinding tank, and the two ends of the grinding tank are sealed with plugs and placed in an electromagnetic vibration drum coil. The electromagnetic coil and the grinding tank are immersed in liquid nitrogen for pre freezing and impact grinding. The entire process is in a liquid nitrogen environment (-196 ℃). The magnetic force generated by the electromagnetic vibration coil drives the impact column to move horizontally back and forth, continuously impacting the sample, causing the frozen and brittle sample to be quickly ground and crushed.

Performance advantages

Adopting the principle of electromagnetic vibration impact, the grinding speed is fast, the precision is high, the uniformity is good, and the repeatability is good;
Adopting a streamlined design that conforms to the principles of human dynamics, the operation is simple and convenient, and the color matching is beautiful and fashionable;
Easy to operate control panel, adjustable impact frequency, pre freezing time, impact grinding time, cycle grinding times, etc;
Adopting a liquid nitrogen automatic filling system to automatically replenish the liquid nitrogen consumed during the sample freezing and grinding process, ensuring the stability and safety of freezing and grinding;
○ Safety performance design: When the instrument cover is in the open state, the instrument cannot be started; The instrument can only be started when the cover is closed and locked.
