Experimental Grinding Machine "RETSCH Planetary Ball Mill PM400"
Planetary Ball Mill PM 400
Supports colloid grinding and mechanical alloying! A turntable with four floor models.
The "Planetary Ball Mill PM400" is a robust floor model laboratory grinding machine with four rotating platforms. It is capable of ultra-fine grinding and can handle advanced applications such as colloidal grinding and mechanical alloying, in addition to mixing and grinding for sample preparation. The powerful combination of two centrifugal forces from rotation and revolution enables grinding in a short time. An optional internal pressure and temperature measurement system, "PM GrindControl," is available. 【Features】 ■ Powerful and rapid grinding down to sub-micron levels ■ High reproducibility by controlling energy and speed ■ Continuous operation for long periods is possible ■ Compatible with both dry and wet grinding methods ■ Safety slider that prevents operation if the clamp is not attached ■ Interactive condition input with a liquid crystal screen and a single button ■ Back fan in the grinding chamber for air cooling of the grinding jars ■ Up to 10 grinding conditions can be registered ■ Grinding start time can be set with a timer ■ Grinding conditions and remaining time are remembered even in the event of a power outage ■ O-rings are used to enhance the sealing of the grinding jars *For more details, please refer to the PDF document or feel free to contact us.

Company information
Varda Scientific covers a wide range of products, from sample grinding, crushing, homogenization, and heat treatment for laboratory use, to particle size measurement, component analysis, cutting, polishing, embedding, and hardness testing. Varda Scientific has five brands: Leco, QATM, Carbolite Gero, Eltra, and MRB. Since 1999, we have been operating as Leco Corporation, handling products from Leco and Leco Technology. On January 1, 2014, we began handling Carbolite Gero, and at the same time, in line with the increase in the number of brands we handle, we changed our company name to Varda Scientific Corporation. In 2018, we started handling ATM and Qness, and in June 2019, MICROTRAC and Microtrac Bell joined the Varda Scientific Group. As of May 1, 2020, ATM and Qness merged to become QATM, further enhancing our capabilities and allowing us to better meet our customers' needs.
