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 grinderLM200Keep the sample at a low temperature of -196 ℃ to make it brittle and prevent the volatilization of volatile substances in the sample. The structure and composition information of the sample are effectively preserved, thereby achieving good grinding effect.
*The electromagnetic impact force ensures the effectiveness of grinding. The automatic control function of liquid nitrogen quantity avoids the contact and danger of manual operation.Freezing grinderIt can also be used for dry grinding at room temperature, making it an ideal instrument for processing thermosensitive samples and grinding various samples for biochemical DNA/RNA detection.
Application Areas
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.
working principle
Use electromagnetic oscillation impact to grind and crush samples. Place the sample and metal impact column together into a grinding jar, seal both ends of the jar with plugs, and then place it into an electromagnetic vibration drum coil. The electromagnetic coil and grinding tank are immersed in liquid nitrogen for pre freezing and impact grinding, and the entire process is carried out in a liquid nitrogen environment (-196 ℃). The magnetic force generated by the electromagnetic vibration coil drives the impact column to make horizontal reciprocating motion, continuously impacting the sample, causing the frozen and brittle sample to be quickly ground and crushed.
Fully automatic freeze grinderLM200 product features
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;
Multiple specifications of grinding cans and impact columns, suitable for a wider range of applications
We offer a variety of sizes of grinding cans for customers to choose from, suitable for grinding various types of hard, medium hard, soft, brittle, elastic, and fibrous samples.
In order to achieve better grinding results, it is necessary to choose a suitable size of grinding tank according to the amount of grinding samples. It is recommended that the sample filling amount be 5% -25% of the grinding tank volume (depending on the characteristics of different samples).

A cryogenic grinder, also known as a low-temperature grinder, is a sample grinding pretreatment instrument that adds temperature control treatment to a conventional laboratory ball mill. It can achieve fine grinding of samples in low-temperature environments or indoor constant temperature environments. Common ones include low-temperature planetary ball mills, low-temperature vibration ball mills, and low-temperature tissue grinders.
