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.
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.
