The RETSCH 207490001 CryoMill is a highly specialized product designed for cryogenic grinding. This cutting-edge mill is equipped with an integrated cooling system that continually cools the grinding jar with liquid nitrogen before and during the grinding process. This unique feature ensures that the sample is embrittled, preserving any volatile components.
The CryoMill utilizes liquid nitrogen, which circulates through the system and is replenished from an Autofill system. This system precisely maintains the temperature at -196 °C, guaranteeing optimal performance. The powerful impact ball milling technology employed by this mill ensures perfect grinding efficiency.
One of the standout advantages of the CryoMill is its safety features. The Autofill system eliminates any direct contact with LN2, making cryogenic grinding exceptionally safe. Additionally, this mill's versatility allows for both cryogenic and wet and dry grinding at room temperature, making it the ideal grinder for a wide range of applications.
In terms of functionality, the CryoMill employs radial oscillations in a horizontal position. The grinding balls' inertia causes them to impact with high energy on the sample material, effectively pulverizing it. The grinding jar is continuously cooled with liquid nitrogen from the integrated cooling system, ensuring optimal results.
The CryoMill finds applications in several industries, including animal feed, bones, chemicals, food, oil seeds, paper, plant materials, plastics, textiles, and more. Its user-friendly interface makes operation simple and efficient. The mill has memory for storing up to 9 Standard Operating Procedures (SOPs) and offers programmable cooling and grinding cycles.
An additional product that may catch your interest is the High Energy Ball Mill Emax. This unique mill combines high friction and impact to produce extremely fine particles in a short amount of time.
Overall, the RETSCH 207490001 CryoMill is a highly efficient and versatile mill that offers powerful cryogenic grinding capabilities. With its various safety features, convenient operation, and wide range of applications, this mill is an excellent choice for laboratories and research facilities.
The RETSCH 207490001 CryoMill is tailored for cryogenic grinding. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process. Thus the sample is embrittled and volatile components are preserved. The liquid nitrogen circulates through the system and is continually replenished from an Autofill system in the exact amount which is required to keep the temperature at -196 °C. Powerful impact ball milling results in a perfect grinding efficiency. The Autofill system avoids direct contact with LN2 and makes cryogenic grinding very safe. Its versatility (cryogenic, wet and dry grinding at room temperature) makes the CryoMill the ideal grinder for quantities up to 20 ml.
You may also be interested in the High Energy Ball Mill Emax, an entirely new type of mill for high energy input. The unique combination of high friction and impact results in extremely fine particles within the shortest amount of time.
Function Principle
The grinding jar of the CryoMill performs radial oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jar and pulverize it. The grinding jar is continually cooled with liquid nitrogen from the integrated cooling system before and during the grinding process.
