NIX-521 has safe on air circulation heating system without heating element in chamber.


Three-steps acceleration and three-steps 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.


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 and a half (*) after release from ECO mode.

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


From micro tubes to 250ml bottles

The NIX-521, 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.

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 & Ecology

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.

  • Non-chlorine, ozone-friendly refrigeration medium which has zero ozone layer destruction coefficients is adopted.

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.

One-push rotor locking knob

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