| Description | The Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction, either in batches or continuously. It can process dry, soft, medium-hard, organic and inorganic substances.
Its high speed in comparison to the SR 200 allows a significantly higher throughput and fineness.
The SR 300 isThe Rotor Beater Mill SR 300 is suitable for coarse and fine size reduction, either in batches or continuously. It can process dry, soft, medium-hard, organic and inorganic substances.
Its high speed in comparison to the SR 200 allows a significantly higher throughput and fineness.
The SR 300 is intended for universal use: from sample preparation in laboratories up to preparing sample batches in pilot plants or production facilities. The grinding chamber, the feed hopper and the material inlet are completely made from high quality stainless steel.
Features
- Suitable for batchwise operation of larger quantities
- Central locking device
- Wide range of accessories including various collection and feeding systems, rotors and sieves
- High final fineness
- Exchangeable grinding and sieve inserts
- Grinding chamber, feed hopper and material inlet and outlet of stainless steel
- Optional grinding inserts 180° for grinding of hard-brittle materials by additional impact
- Optional distance rotor to reduce frictional heat
- Removable hopper for easy cleaning
- Motor brake
- Defined final fineness due to bottom sieves with aperture sizes from 0.08 - 10 mm

... 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)

The instrument runs steadily and smoothly, even with heavy grinding sets, at maximum speed thanks to the new Stabilized-Plane-The Vibratory Disc Mill RS 200 is suitable for the extremely quick, loss-free and reproducible grinding of medium-hard, brittle and fibrous materials to analytical fineness. The instrument runs steadily and smoothly, even with heavy grinding sets, at maximum speed thanks to the new Stabilized-Plane-Drive.
With its robust design, the RS 200 has proven to be ideal for use in the building materials sector (cement), in geology, mineralogy, metallurgy and in power plants. Due to the high end fineness and speed the RS 200 is the perfect mill when it comes to preparing samples for spectral analysis.
Features - Reproducible results due to "Stabilized-Plane-Drive" (avoid tumbling of the grinding set)
- Safety interlock
- Variable speed 700 - 1,500 min-1
- Extremely short grinding time
- Agate recognition for automatic speed reduction
- 10 SOPs can be stored
- No sample loss thanks to optimum o-ring seal
- Wide range of materials for contamination free grinding
- Noise-insulated grinding chamber
- Quick-action grinding set clamping device
