Retsch CryoMill, 100–240 V, 50/60 Hz, tailored for cryogenic grinding, (please order Autofill with LN2 container and safety valve, grinding jars and balls separately)

A ball mill for powerful size reduction and homogenization

RETSCH ball mills are available as mixer mills as well as planetary ball mills.

Mixer Mills grind and homogenize small sample volumes quickly and efficiently by impact and friction. They are suitable for dry, wet and cryogenic grinding as well as for cell disruption for DNA/RNA recovery.

RETSCH’s innovative Planetary Ball Mills meet and exceed all requirements for fast and reproducible grinding down to the nano range. They are used for the most demanding tasks, from routine sample processing to colloidal grinding and advanced materials development.

The High Energy Ball Mill Emax is 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.

The 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 LN2and 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.
