The VWR® symphony™ 4417 series includes both the ambient model 4417 and the refrigerated model 4417R centrifuges. Various fixed angle and swing-out rotors are available to process a variety of different tube types from 0.2 to 100mL. These units are well suited for use with all standard blood collection， conical and microcentrifuge tubes， as well as standard and deep-well microplates. High speed and g-force make the 4417 series ideal for applications ranging from clinical to cell culture and molecular biology. Powerful， brushless motors quickly accelerate rotors to the preset speed. Braking is dynamically controlled to bring the rotors to a soft stop without disrupting fragile samples. Operation of the centrifuge may be timed， continuous， or momentary.The rotor recognition system in the 4417 series provides safety and convenience when different rotors are used. Each rotor is recognized at the beginning of a run and automatically limited to its rated maximum speed. In addition， by recognizing the rotor， the microprocessor can accurately calculate and display g-force during a run. Electrical rating for each unit is 230V.
