ECO mode to realize an up to approximately 24% duling the wating time.

[ECO] modo Electric power saving

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 (*2) after release from ECO mode.

*2 Under the conditions: set temperature of 4℃ at an ambient temperature of 25℃.


Power consumption at ECO mode

  • Measurement conditions: Set to 4℃ at an ambient temperature of 25℃ while centrifugation is stopped.
    (Rotors in use: CAX-571: TS-7C+7215-06)
  • The values shown above are average values obtained by measuring the units.


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.

From micro tubes to 250ml bottles

CAX-571, with the ability to accommodate micro tubes to 250ml bottles or deep well plates, is ideal for wide range of applications. Using an optional bucket cap kit B433HS*, various types of rotors including swinging bucket rotors of biohazard-proof can be mounted.

Convenient flashing function

Convenient flashing function allows operation with preset centrifuging conditions.

*Bucket cap kit B433 is an optional kit.
HS This highly sealed rotor, which has been tested and certified by the Health Protection Agency (HPA, UK) to be compliant with the International Standard (Annex AA of the IEC 61010-2-020), meets requirements for biohazard safety. [Bucket cap kit B433] is an optional kit.

Compact Design

Compact design for minimum space requirement

コンパクト設計With its compact design of 462mm width and 542mm depth it is ideally suited to applications where space is limited.

Easy to see and operate control panel

Easy-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; red indicates that the rotor is spinning while green indicates the rotor is stopped.

Popular user-friendly Jog Dial equipped with an <ENTER> button on top enables setting to be changed quickly and more surely.

Safety & Convenience

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.

One-push rotor locking knob

With a single knob push, the rotor can be quickly and securely fixed.
*Some rotors are excepted.

Flex-Spin Drive [Sample Movie]

The 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.
