Refrigerated High-Speed Centrifuge M20R, 20000 rpm (CAT#: STEM-AL-6673-ZJF)

The M20R is a refrigerated high-speed centrifuge designed for temperature-controlled biological sample separation. It supports controlled centrifugal processing of compatible laboratory vessels and sample formats with a maximum capacity of 400ml(100ml×4). The drive system regulates rotor speed across the stated operating range of 100-20000rpm/increment 10rpm. Timed operation allows repeatable spin protocols and supports routine sample-preparation workflows. Integrated lid, speed, and imbalance monitoring are used where specified to support safe centrifugation. Compatible rotors, adapters, or plate holders allow the instrument to accommodate the sample formats listed for the model. Temperature control and active refrigeration support heat-sensitive samples during centrifugation. The instrument is suited to clinical, molecular, biochemical, or general laboratory separation workflows described in the source data.
