The Easy Operation of a Color Touch Screen LCD

Hitachi Koki himac CR22N High-Speed Centrifuge Touch Screen LCD Screen Shot

A high resolution color touch LCD and the unique graphic user interface with high contrast against back screen in black color enable users to easily operate the system or select various menus and functions by touching the icon on the display.


Self-Locking Rotor System

Hitachi Koki himac CR22N High-Speed Centrifuge Self-locking Rotor System As simple as it sounds. Place the rotor onto the drive shaft and that's it. By using centrifugal force the rotor automatically locks into position. There is no need for the use of tools, screws, and/or buttons.

Automatic Rotor Identification

Hitachi Koki himac CR22N High-Speed Centrifuge Automatic Rotor Identification Rotors are automatically identified to optimize running conditions to compensate for air friction and apply precise temperature control.

Rotor Management

Hitachi Koki himac CR22N High-Speed Centrifuge Rotor Management

Rotors can be registered to the CR22N system to manage rotor:

  • Serial numbers
  • Total accumulated operating (hours)
  • Total Number of Operation (runs)

Rotor management can be accessed on-screen by selection the rotor management icon.

Safety Features


Non-Contact Imbalance

Hitachi Koki himac CR22N High-Speed Centrifuge Non-Contact Imbalance Detection System The imbalance detection system uses a sensor to continuously measures oscillation over the entire rpm range.  The system immediately detects abnormal vibrations caused by the imbalance of the rotor and stops the rotation of the rotor automatically.

Automatic Rotor Cover Detector

  A sensor detects rotor cover status to prevent unexpected accidents.


A Smaller Footprint while Maximizing Capacity

A re-engineered drive unit and the introduction of a 1.5 liter bottle the CR22N now features a 6-liter rotor (1.5L x 4 bottles) capacity while the slim footprint allows the CR22N to fit nicely into any laboratory. 

Green Friendly Features

"ECO" Mode

Hitachi Koki himac CR22N High-Speed Centrifuge ECO Mode
Over a period of time if the touch screen display has not been it use the system will automatically dim the screen and discontinue the use of refrigeration (except in run mode) to reduce energy consumption up to 83% of standby electricity. You may also press the “eco” button on the touch screen display to put the CR22N in standby mode manually.

A Drive Unit with a Re-generating Brake System Saves

Kinetic energy produced from the spinning rotor produces the energy needed to brake the rotor saving electricity. The heat is exhausted into the room to reduce temperature build up in the centrifuge bowl. The re-braking system has the ability to return up to 40% of electricity used.


Environment Friendly Design

Refrigerants used in the CR22N have an ODP (ozone depletion potential) level of 0. Over 80% materials of the product are reusable or recyclable.
