Note: The bottom hole of the angular rotor configured in 2012HR is conical without magnetic column, so it cannot be automatically identified. The rotor model when centrifuging should be set directly on the interface.

02Product Advantage

Overall Machine Features

Microcomputer control, equipped with a large-screen true-color LCD display and a full-touch operation interface; directly set working programs, centrifugal force, rotation speed, centrifugation time, temperature, acceleration and deceleration, with simultaneous LCD display of rotor model.

Driven by a brushless AC variable-frequency motor, using a dedicated drive module to ensure circuit reliability.

Double door lock system; the door automatically locks upon startup to ensure operational safety.20 working program options; users can freely program and call up the set working parameters for easy use and improved work efficiency.

15 acceleration gears / 15 deceleration gears; users can set any group of acceleration and deceleration according to sample requirements.

Equipped with two timing functions: timing at set rpm and timing upon startup, as well as a shotspin (instant centrifugation) function via one-touch operation.

Differential centrifugation: 5 reserved differential centrifugation programs, which users can set by themselves according to needs.

Double-layer steel structure with a stainless steel centrifugal chamber to prevent corrosion from corrosive substances.

Automatic balancing and unbalance protection; alarm signal prompt and automatic shutdown in case of errors or unbalance.

Parameters can be modified arbitrarily during operation without stopping the machine.

Fastest acceleration/deceleration time: <15s [H0512]

Equipped with SOFT soft brake function, which can effectively prevent sample resuspension and protect sensitive samples; multi-stage damping and shock absorption design to ensure sample centrifugation effect.

Countdown function: counts down in seconds and displays the remaining working time in real time.

The centrifugal chamber is equipped with a condensed water drainage hole to prevent water accumulation in the chamber.

"Standby Cooling" pre-cooling function: can continuously pre-cool to the set temperature in standby mode.

Standby function: when the temperature drops to the set value, the compressor automatically enters standby mode to reduce energy consumption and extend the service life of the compressor.

"Fast Cool/Quick Lock" rapid cooling function: cools down from room temperature (21°C) to biological zero (4°C) in ≤5 minutes.

Rotors can withstand high-pressure sterilization at 121°C for more than 2 hours; airtight angular rotors ensure high biological safety.

Automatic magnetic rotor identification; no manual rotor model setting required (2012HR needs to be set in the interface), with overspeed protection.

Imported compressor unit with fluorine-free refrigeration.

Customizable 485 communication interface for remote control [optional].
