Performance Features
- Adopts ultra-high precision drive head motor structure with cutting-edge technology, ultra-quiet, high-performance and highly reliable. The drive head and shaft are made of super alloy with exceptional rigidity. The drive head matches the angle rotor with ultra-high precision, allowing manual installation and removal without tools.
- Equipped with automatic intelligent rotor identification, automatic imbalance detection and rotor safety self-inspection to ensure safe and reliable operation.
- The drive head and angle rotor are made of aerospace-grade high-strength alloy composite, resistant to all corrosive organic solvents and samples, with lifetime warranty.
- The centrifugal chamber is made of stainless steel ultra-composite alloy, permanently resistant to corrosive samples and solvents, durable with lifetime warranty.Surface performance: hardness ≥ 2300HV, smoothness ≤ 0.04, no damage after 100-hour salt spray test.
- Customized three-stage buffer hydraulic lid rod with dust cover ensures smooth and durable lid opening.
- 7-inch HD touch screen intelligent system displays speed, running time, temperature, acceleration/deceleration levels, rotor model, max. speed, max. RCF, lid status and real-time date & time simultaneously.
- Centrifugal force or speed can be preset to meet different application requirements. Programmable mode supports full-function operation to satisfy various research needs.
- Real-time speed monitoring: in case of abnormal operation, a pop-up alarm is activated and all buttons are locked to prevent misoperation hazards.
- Operation data is recorded in the background and can be viewed in real time. Curves of speed, RCF and temperature are displayed on one screen for clear data recording.User-friendly design: adjustable brightness, key tone, Chinese/English language, timing mode and automatic lid opening.
- The refrigeration system adopts advanced micro automatic constant temperature control technology, greatly improving cooling accuracy and compressor service life.Cools rapidly from 25℃ to 4℃ within 3 minutes.
- Automatic refrigeration system: stops when lid is open, restarts when closed. Independent temperature control switch is available.
- High-quality copper tubes with full tin welding are used for the refrigeration coil, greatly improving cooling efficiency with automatic condensate drainage.
- Unique octagonal cavity structure with solid reliability. Automatic ventilation system outside the cavity; all circuit boards are suspended for excellent moisture protection.
- Patented triangular linkage motor fixation and three-stage damping system firmly fix the motor at the bottom for stable high-speed running.
- The whole casing is made of composite material with baking finish, highly resistant to acid and alkali corrosion, no damage after 100-hour smoke test, stylish and durable.
- Ergonomic design with elegant appearance and easy operation. Equipped with lid protection, over-speed, over-temperature, imbalance protection and automatic fault alarm for stable and reliable use.
