Verder Scientific - 20.745.0001 - Retsch 20.745.0001 Mixer Mill MM400; 100-240 VAC, 50/60 Hz

ITEM #: 4170103
Quick and effective - most materials can be pulverized and mixed at ambient temperature without any cooling! Suitable for dry, wet, and cryogenic grinding as well as cell disruption for DNA/RNA recovery Two grinding stations and short processing times provide high sample throughput Reproducible results by digital preselection of grinding time and vibrational frequency 2 year warranty This high-performance mixer mill can pulverize two samples from 0.2 to 20 mL at the same time. The compact benchtop model is suitable for size reduction, mixing and pulverization of hard, medium-hard, brittle, soft, elastic and fibrous samples. It is also useful for mixing and homogenization of powders. The grinding jars perform oscillations in a horizontal position. The inertia of the grinding balls causes them to impact with high energy on the sample material at the rounded ends of the grinding jars and pulverize it. Also, the movement of the grinding jars combined with the movement of the balls result in the intensive mixing of the sample. As a function of frequency, up to 1800 impacts per minute are achieved resulting in a high degree of pulverization in very short times. The degree of mixing can be increased even further by using several smaller balls. If many very small balls are used (e.g. glass beads) then, for example, biological cells can be disrupted. The large frictional impact effects between the beads ensure effective cell disruption. Order screw-top grinding jars and balls separately. Convenient self-locking clamp allows the use of large jars up to 50 mL. This listing is for Each.
