  • Competitive Advantage

High speed refrigerated centrifuge TR21M-HI is typically used in scientific research and medical laboratories to separate substances of different densities in a sample. The refrigeration feature allows for temperature control during the separation process, which is important for maintaining the integrity of certain samples.


● Metal housing, metal lid, and stainless steel centrifuge chamber are autoclave-able and resistant detergents and disinfection liquids.

● Observations window on lid for speed calibration and noise measurement.

● Microprocessor control with frequency conversion A.C. motor drive

● LCD Display the parameters of Speed, Timer, RCF, Rotors, Program(Memory), Acceleration& Deceleration information and Error code information.

● Double layers sealing ring made for the centrifuge lid and the instrument to keep long good sealing.

TR21M-HI high-speed refrigerated centrifuge

User friendly

● CFC free refrigeration system, Pre-cooling feature, Precise temperature control up to – 20°C.

● Programmable and storable, stores up to 30 programs and provides direct user access with one keystroke save. The stored parameter: combination remains in the memory even after the centrifugation has been switched off.

● Provides the 10 acceleration rates and 10 braking ramp, to effectively avoid secondary sedimentation, with better centrifugation effect.

● Automatic lid-locking and holding during rotor run

● Easily exchangeable rotors, special rotor connector which makes it easy to load and unload rotor.

● Automatic troubleshooting with indication of error code and alarm on the screen.

● “Mute”patent technology. Noise level lower than 58 decibel at the highest rotational speed.

● Automatic rpm/rcf conversion

● Automatic rotor identification system, coded rotor identification prevents the rotor from over speeding.

TR21M-HI high-speed refrigerated centrifuge


● Produced according to international safety regulations (e.g. IEC 61010)

● Safety Electrical lid interlock,door can not open when rotor is running and machine won’t run when lid open and error code appears.

● Emergency lid-lock release when power failure(very useful in an unexpected power interruption).

● Gas hinge for lid drop protection.

● Safety protections are made for the over speed, over heating(motor, chamber), imbalance etc to ensure the man machine safety.
