Velocity 18RRefrigerated Benchtop CentrifugeThe Velocity 18R delivers high capacity, refrigeratedcentrifugation with an impressive maximum speed of 18,000RPM (27,070 x g) (with the fixed angle FA18 rotor) and all fromthe convenience of the benchQuick Set and Forget Rotor SystemScrewing or bolting rotors to the drive shaft is a thing of thepast. Likewise lost spanners and rotor over tightening. With theVelocity 18R simply place the rotor on the drive shaft and that’sall. The auto lock and secure mechanism performs the rest. Oncecentrifugation is complete, simply lift the rotor off the driveshaft. Quicker, easier, more efficient and safer.Auto Rotor RecognitionAutomatic rotor recognition and confirmation once centrifugationhas commenced, including rotational speed calculation andoptimum temperature control.Furthermore new rotors can be easily loaded onto the on-boarddatabase as they are introduced.Fast Acceleration and DecelerationThe innovative high torque, drive technology effortlesslyaccelerates even the heaviest rotors to terminal velocity quicklyand effi ciently. Even the heaviest rotors with a full load willachieve maximum velocity within a few minutes. Furthermore, 9pre-set acceleration and 9 pre-set deceleration profiles ensurethe best separation even for the most delicate density gradientsHigh Imbalance TolerancesInnovative motor engineering and mounting including a flexibledrive shaft allow for greater imbalance tolerances, so thatsamples can be balanced simply with the naked eye. No moreweighing just fi ll tubes or bottles to within 5mm of each other.Powerful RefrigerationA powerful non -CFC compressor cools the chamber quicklywhilst maintaining the rotor at set temperature duringcentrifugation. Furthermore, twin cooling fans - one each for thecompressor and motor respectively - dissipate heat quickly toimprove cooling effi ciency and extend motor life.Actual Sample (Rotor) Temperature Measurement andDisplayThe temperature displayed on the LCD panel duringcentrifugation is that of the rotor (and hence samples) and notthe temperature of the chamber nor the temperature at thesensor to allow for more precise, reproducible and effi cientexperimentation.Safety is ParamountThe Velocity 18R offers many safety features in the unlikelyevent of an emergency such as:Non-contact imbalance detection and shutdown based on therun profi le for each rotor across its entire speed range ratherthan the inferior and conventional micro-switch detector.> Guard barrier> Dual lid electronic interlock> Auto-hinge for improved sealing and door opening> Over speed detection and shutdown> Motor overheat detection and shutdownUser Friendly OperationParameters are quickly and effortlessly inputted through theuncomplicated touch pad interface and displayed on the brightlybacklit and easy to read LCD panel.The LCD panel concurrently displays all experimentationparameters including diagnostic information as it occurs.Furthermore, once centrifugation has commenced, a real timegraphic profi le of the centrifugation status is displayed.Quiet OperationNoise abating insulation in the console including lower noisefans combine to reduce the audible operating noise to ≤58 dB.Liquid Seeping PreventionA single continuous rubber cap with strong gasket, fi rmly sealsthe motor chamber opening and drive shaft to prevent liquid fromseeping into the motor and electronic components. As additionalback-up, a highly absorbent sponge positioned beneath therubber cap soaks up any liquid or condensation which thenevaporates during operation.30
