Key Features

Ultra-High Precision Drive System
Features a cutting-edge, ultra-quiet, high-performance drive motor with a superalloy shaft and drive head. No tools required to change rotors — they can be installed and removed manually with ease.

Intelligent Rotor Recognition
Automatically detects rotor type and imbalance, with built-in safety checks to ensure reliable, secure operation.

Aerospace-Grade Materials
The drive head and angle rotors are made from aerospace-grade superalloy composite materials, offering lifetime resistance to corrosive organic solvents and samples.

Reinforced Stainless Steel Chamber
Made from super-composite stainless steel alloy, permanently resistant to corrosive substances. Surface durability tested with over 100 hours of salt spray. Surface specs: >2300 HV hardness, <0.04 smoothness.

Custom Hydraulic Lid Support
The lid is supported by a three-stage buffer hydraulic rod with a dust cover, ensuring smooth and reliable lid operation.

7-Inch HD Touchscreen Display
Intuitive interface shows speed, time, temperature, acceleration/deceleration levels, rotor model, and system status, including real-time clock and date.

Customizable Program Mode
Users can preset centrifugal force or speed based on requirements, save custom programs, and access full control over all functions.

Real-Time Monitoring & Safety Alerts
Live speed monitoring detects abnormalities. If the motor functions incorrectly, a warning pops up and disables all controls to avoid user error.

Advanced Data Display
Automatically records and displays real-time curves for speed, force, and temperature. Users can customize system settings, including brightness, sound, timing mode, language (English/Chinese), and auto lid functions.

Industry-Leading Cooling System
Micro-automatic constant temperature control brings temperature from 25°C to 4°C in under 3 minutes. The compressor system is designed for high accuracy and extended service life.

Smart Freezing Controls
The refrigeration automatically pauses when the lid is opened and resumes when closed. Pre-cooling to 4°C is also possible.

High-Efficiency Copper Tubing
Copper tubing with full-tin welding improves cooling efficiency. Features automatic drainage of condensed water.

Octagonal Chamber Design
Strong chamber with integrated ventilation and suspended circuitry for excellent moisture protection and durability.

Patented Motor Fixation and Shock Absorption
The triangular linkage motor mount and three-stage shock absorption system provide superior stability during high-speed operation.

Durable, Chemically-Resistant Outer Shell
Treated with baked paint and composite materials, the outer shell resists acid and alkali corrosion — remains unaffected after 100 hours of smoke testing.

User-Friendly, Safe, and Ergonomic
Designed for ease of use with door-lid protection, imbalance detection, overspeed/overheat safety features, and automatic fault alarms.
