GL-21M Floor-Standing Refrigerated High-Speed Centrifuge, 21,000 rpm (CAT#: STEM-AL-3693-ZJF)

GL-21M Floor-Standing Refrigerated High-Speed Centrifuge is designed for temperature-controlled high-speed biomolecule separation. It uses controlled centrifugal force to separate sample components according to density. The instrument supports the stated rotor capacity and compatible vessel formats. Electronic control regulates rotor speed and operating time. An integrated refrigeration system regulates the chamber within the documented temperature range. The display presents speed, time, temperature, and available centrifugal-force information. The chamber and rotor arrangement support routine loading, balancing, and sample recovery. Protective functions address overspeed, imbalance, and door conditions according to the source configuration. The system supports repeatable separation workflows within the specified operating limits.
