User Friendly and Safety Features

Flex-Spin System for safer and more efficient operation

Innovative Flex-Spin System employed to maintain safe and efficient centrifugal operation allows a margin of error and eye-balancing of sample tubes.
  • * 
    Some rotors are excepted.


  • CAX-571 is equipped with a function to automatically reduce the rotation speed and shut the system down if it is being run over the imbalance tolerance limit.
  • Non-chlorine, ozone-friendly refrigeration medium which has zero ozone layer destruction coefficients is adopted.
  • Flex-Spin Drive

    Flex-Spin Drive features a flexible motor shaft that equalizes minor imbalances without damaging the centrifuge or triggering the imbalance protection system. This allows excellent tolerance for minor differences in sample volumes.
  • One-push rotor locking knob

    With a single knob push, the rotor can be quickly and securely fixed.

    • * 
      Some rotors are excepted.
    • To mount the rotor

      Pressing the red snap on the locking knob down

      Place the locking knob on the shaft and secure the rotor to the shaft by pressing the red snap on the locking knob down the shaft until it “clicks”.
    • To dismount the rotor

      Pull the locking knob out from the shaft

      Pull the locking knob out from the shaft, while holding down the red snap on the top.

Intuitive Display and Control Panel

LCD monitor display
1Easy-to-see LCD monitor display shows various information including remaining run time, error messages, rotor types in use and records of centrifugal operation. The monitor can display in English or Japanese.
  • * 
    Indication displays on the control panel in the photo is different from displays of actual operation.
Dual color LED display allows the user to monitor the operation status just by looking the display
2Dual color LED display allows the user to monitor the operation status just by looking the display; red indicates that the rotor is spinning while green indicates the rotor is stopped.
3Popular user-friendly Jog Dial equipped with an <ENTER> button on top enables setting to be changed quickly and more surely.
  • Compact Design

    Compact Design
    With its compact design of 462 mm width and 542 mm depth it is ideally suited to applications where space is limited.

    Convenient Flashing Function

    For quick spin-down.
  • Three-step acceleration and three-step and natural deceleration

    Three-step acceleration and three-step and natural deceleration
    Initial values for acceleration and deceleration characteristics are set from 0 to 500rpm, however, they can be varied up to maximum speed in 100rpm increments by function settings.

Environmentally Friendly

ECO mode

  • ECO mode to realize an up to approximately 24% during the waiting time.
    [ECO] mode
    [ECO] key
    Activating the power-saving [ECO] mode can also help reduce the power consumption during the waiting time (standby cooling) by allowing the temperature control bands to be changed.The chamber can cool down to the set temperature within approximately 3 minutes * after release from ECO mode.
    • * 
      Under the conditions: set temperature of 4℃ at an ambient temperature of 25℃.
  • Power consumption at ECO mode

    Power consumption at ECO mode
