| Description | The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.
The The CryoMill is a laboratory ball mill specifically designed for this application. It features an integrated cooling system which continually cools the grinding jar with liquid nitrogen before and during the grinding process. Thus, the sample is embrittled and volatile components are preserved.
The liquid nitrogen is continually supplied from an autofill system in the exact amount required to keep the temperature at –196 °C. The CryoMill's versatility makes it the ideal grinder for sample quantities up to 20 ml.- powerful grinding by impact and friction with up to 30 Hz
- pulverization of two samples down to 5 micron
- The user never comes into direct contact with LN2 which ensures a high degree of operational safety
- adapter for keeping 2 ml plastic tubes or 2 ml steel tubes available
- special jar zirconium oxide available for heavy-metal free grinding
- suitable forgrinding in interval
- 3 different grinding modes (dry, wet or cryogenic)
- memory for 9 SOPs
- Screw-Top jars

With four sharp, robust blades and a powerful motor which can reach temporary peaks of 3 kW, it is ideal for The new knife mill GRINDOMIX GM 300 is the ideal instrument for the grinding and homogenization of foodstuffs. It allows to process sample volumes up to 4.5 liters quickly and reproducibly.
With four sharp, robust blades and a powerful motor which can reach temporary peaks of 3 kW, it is ideal for homogenizing substances with a high water, oil or fat content as well as for grinding dry, soft and medium-hard products. The GRINDOMIX GM 300 meets and exceeds all special laboratory and analytical requirements and is a professional device superior to any commercial household mixer.
Features - Efficient size reduction of up to 4,500 ml feed quantity due to a powerful 1.1 kW motor (peak power input >3 kW)
- Pre- and fine-grinding in one mill: cutting action in regular mode, grinding by impact in reverse mode, pre-grinding in interval mode
- All parts which come into contact with the sample material are autoclavable
- Perfect adaptation to application requirements by variable speed from 500 to 4,000 min-1 with an increment of 100 min-1
- Optional gravitation lid for automatic reduction of the grinding chamber volume
- 10 SOPs can be stored
- Grinding jar in plastic and stainless steel available
... Read More | The Planetary Ball Mill PM 300 is a powerful and ergonomic benchtop model with two grinding stations for grinding jar volumes up to 500 ml. This setup allows for processing up to 2 x 220 ml sample material per batch. Thanks to the high maximum speed of 800 rpm, extremely high centrifugal forces The Planetary Ball Mill PM 300 is a powerful and ergonomic benchtop model with two grinding stations for grinding jar volumes up to 500 ml. This setup allows for processing up to 2 x 220 ml sample material per batch. Thanks to the high maximum speed of 800 rpm, extremely high centrifugal forces result in very high pulverization energy and consequently in short processing times. The PM 300 is ideally suited for virtually all industries where the quality control process places the highest demands on purity, speed, fineness and reproducibility. Thanks to its enormous energy input of up to 64.4 times the acceleration of gravity, this mill is the perfect choice for tasks in research like mechanochemistry (mechanosynthesis, mechanical alloying and mechano-catalysis), or for ultrafine colloidal grinding on a nanometer scale.- powerful grinding by impact and friction with up to 800 rpm
- pulverization of two samples down to 100 nm
- jars from 12-500 ml
- adapter for keeping 2 ml gas chromatography glass vials for cocrystal screening
- high energy input of up to 64.4 g
- suitable for mechanochemistry applications and mechanical alloying
- Ergonomic clamping unit with smooth surfaces
- Automatic grinding chamber ventilation with directed air stream for perfect jar cooling
- The Safety Slider prevents starting the machine without securely clamped jars, perfect stability on the lab bench thanks to FFCS -technology
- Comfortable parameter setting via Touch display
- 2 different grinding modes (dry, wet)
- memory for 12 SOPs and 4 program cycles
- 5 different jar materials
jars of 12 – 80 ml can be stacked (two jars each)
