The Spectrafuge 16M is the perfect, high speed, compact microcentrifuge. A brushless, maintenance free motor provides extremely fast acceleration and deceleration of the 18 place rotor and makes the Spectrafuge 16M the quietest microcentrifuge in its class.  Speed and time are set with the control knobs on the front panel of the unit. A ?quick? button allows for momentary runs. A continuous flow of ambient air through the rotor chamber keeps the rotor and samples cool. For applications requiring subambient temperatures, the Spectrafuge 16M can be operated in a cold room. The Spectrafuge 16M is supplied complete with an 18 place rotor for 1.5/2.0 ml tubes. Smaller tubes are accommodated by adapters (sold separately). The optional StripSpin™ rotor adapter holds two 8 x 0.2 ml strips, typically used for thermal cycling.SpecificationsSpeed: 1,000 to 14,000 rpmMax. RCF: 16,000 x gMax.
