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].
