Performance Features

• Adopts ultra-high precision drive head motor structure with latest technology, ultra-quiet, high performance and reliability. Drive head and shaft are made of super alloy with high rigidity. Drive head matches fixed angle rotor with high precision; rotor can be installed or removed manually without tools.
• Rotor automatic intelligent identification, automatic imbalance detection and rotor self-inspection ensure safe and reliable operation.
• Drive head and fixed angle rotor adopt aerospace-grade super alloy composite material, resistant to all corrosive organic solvents and samples, lifetime warranty.
• Centrifugal chamber is made of stainless steel ultra-composite alloy, permanently resistant to all corrosive samples or 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, ensuring 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, real-time date and time simultaneously.
• Centrifugal force or speed can be preset according to user needs. Programmable mode is available to meet various research requirements.
• Real-time speed monitoring: if motor runs abnormally, the system alarms and locks buttons to avoid misoperation.
• Operation data is recorded in the background and can be viewed in real time. Curves of speed, RCF and temperature are displayed on the same screen for clear data recording.
• User-friendly design: adjustable screen brightness, button sound, Chinese/English language, timing mode and automatic lid opening.
• The whole refrigeration system adopts advanced micro automatic constant temperature control technology, which greatly improves cooling accuracy and service life of compressor.

  Cools from 25℃ to 4℃ in less than 3 minutes.

• Automatic refrigeration system: stops when lid is open, restarts when closed. Independent refrigeration switch is available.
• High-quality copper tubes with full tin welding for the refrigeration system, plus automatic condensate drainage, improving cooling efficiency.
• 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 fixing the motor at the bottom for stable high-speed running.
• Whole casing is made of composite material with baking finish, highly resistant to acid and alkali, no damage after 100-hour smoke test, elegant and durable.
• Ergonomic design with attractive appearance and easy operation. Equipped with lid protection, over-speed, over-temperature, imbalance protection and automatic fault alarm for stable and reliable use.
