HR21M /HR20M
High-Speed Refrigerated centrifuge
Features:
AV motor of variable frequency and high toque,free from contamination caused by carbon dust,which helps to prolong the service life.
Imported variable frequency drive system and automatic control system to ensure steady and reliable operation.
France-based Tecumseh's compressor unit is used for the refrigeration system which allows free temperature adjustment and achieves high-precision temperature controls and reduced noise.
Maximum capacity 6x500ml,Maximum rotation speed 21000rpm.
Multiple protections such as overheat,hypervelocity,electronic locking and imbalance.
Metallic structure with a stainless steel cavity,hence strong and durable.
Intelligent interface featured by a TFT true-color LCD wide-screen touch monitor,micro-computer control and simultaneous indication of both the set parameters and operation one.
With 16 operation programs to be set by the user and the control parameters of the rotor to be modified at any time.
Operations can be programmed,10 levels of speed-up and speed-down time limits for the user to choose freely.
Can indicate the ascending and declining curves of the rotor ,the centrifugal integral curves and the temperature curves.
