Experimental Grinding Machine 'Retsch Mixer Mill MM 500 VARIO'
Lecce Mixer Mill MM500 Vario
Simultaneous grinding of multiple samples + grinding power of up to 35 Hz in the series.
The MM 500 Vario has been added, specializing in the grinding of trace and small samples, capable of fine grinding in just a few seconds to a few minutes. This model, which has six jar holders, can set and process up to six Retsch grinding jars simultaneously. The grinding jars used are the screw cap type with excellent sealing, which are also employed in the existing model MM400 (1.5ml to 50ml). Materials can be selected to match the characteristics of the samples, including hardened steel, stainless steel, tungsten carbide, agate, zirconium oxide, and PTFE. In addition to dry grinding, it also supports wet grinding and cryogenic grinding using liquid nitrogen, allowing for the grinding of various samples with different properties, from soft to hard materials, thus enabling efficient sample preparation. Furthermore, only one ball is required for standard grinding, making sample recovery and cleaning easy, while also avoiding cross-contamination. For homogenization of biological samples and cell disruption using beads, there is a dedicated adapter that can be loaded with disposable tubes (0.2mL to 5mL). It can simultaneously grind up to 50 samples.
