The Velocity 18R delivers high capacity, refrigerated centrifugation with an impressive maximum speed of 18,000 RPM (27,070 x g) (with the fixed angle FA18 rotor) and all from the convenience of the bench.
Quick Set and forget Rotor System
Screwing or bolting rotors to the drive shaft is a thing of the past. Likewise lost spanners and rotor over tightening. With the Velocity 18R simply place the rotor on the drive shaft and that’s all. The auto lock and secure mechanism performs the rest. Once centrifugation is complete simply lift the rotor off the drive shaft. Quicker, easier, more efficient and safer.
Auto rotor recognition
Automatic rotor recognition and confirmation once centrifugation has commenced, including rotational speed calculation and optimum temperature control. Furthermore new rotors can be easily loaded onto the on-board database as they are introduced.
Fast Acceleration and Deceleration
The innovative high torque, drive technology effortlessly accelerates even the heaviest rotors to terminal velocity quickly and efficiently. Even the heaviest rotors with a full load will achieve maximum velocity within a few minutes. Furthermore, 9 pre-set acceleration and 9 pre-set deceleration profiles ensure the best separation even for the most delicate density gradients.
High imbalance tolerances
Innovative motor engineering and mounting including a flexible drive shaft allow for greater imbalance tolerances, so much so that samples can be balanced simply with the naked eye. No more weighing just fill tubes or bottles to within 5mm of each other.
A powerful non -CFC compressor cools the chamber quickly whilst maintaining the rotor at set temperature during centrifugation. Furthermore, twin cooling fans - one each for the compressor and motor respectively - dissipate heat quickly to improve cooling efficiency and extend motor life.
Actual sample (rotor) temperature Measurement and Display
The temperature displayed on the LCD panel during centrifugation is that of the rotor (and hence samples) and not the temperature of the chamber nor the temperature at the sensor to allow for more precise, reproducible and efficient experimentation.
Safety is Paramount
The Velocity 18R offers many safety features in the unlikely event of an emergency such as: Non-contact imbalance detection and shutdown based on the run profile for each rotor across its entire speed range rather than the inferior and conventional micro-switch detector.
Dual lid electronic interlock Auto-hinge for improved sealing and door opening Over speed detection and shutdown Motor overheat detection and shutdown
User friendly operation and information rich display
Parameters are quickly and effortlessly inputted through the uncomplicated touch pad interface and displayed on the brightly backlit and easy to read LCD panel.
The LCD panel concurrently displays all experimentation parameters including diagnostic information as it occurs. Furthermore, once centrifugation has commenced, a real time graphic profile of the centrifugation status is displayed.
Noise abating insulation in the console including lower noise fans combine to reduce the audible operating noise to =58 dB.
Liquid Seeping Prevention
A single continuous rubber cap with strong gasket, firmly seals the motor chamber opening and drive shaft to prevent liquid from seeping into the motor and electronic components. As additional back-up, a highly absorbent sponge positioned beneath the rubber cap soaks up any liquid or condensation which then evaporates during operation.
