A new model, MM500, has been added to the mixer mill, which is compact in size and widely used for sample preparation of small quantities.
The new design of the grinding jar (container) and the adoption of an upgraded drive have improved airtightness and grinding capability, enabling ultra-fine grinding (<0.1 μm) comparable to a planetary ball mill, grinding under gas atmosphere, and long durations for mechanical alloying (MA) and mechanochemical processes. Additionally, the jar capacity has increased to a maximum of 125ml. It also supports freeze grinding, which has gained attention in recent years. 【Features】 ■ The series' maximum grinding power of 35Hz (2100rpm) ■ A new design grinding jar with excellent airtightness suitable for dry grinding, wet grinding, freeze grinding, and grinding under gas atmosphere (pressure resistant up to 5bar) ■ Grinding jar capacities of 50ml, 80ml, and 125ml; two jars can be set simultaneously ■ Suitable for long-duration grinding: ideal for applications in reaction systems such as mechanochemistry ■ Remote operation via smartphone or tablet using the new RETSCH App (sold separately)

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.
