Product Description Conventional brush motor Analog displays and controls Advanced refrigeration capability The Beckman J6-B High Capacity Centrifuge features an extensive list of functionalities including a conventional brush motor and reliable analog display. This Beckman model also features an advanced refrigeration option, a performance speed of 6000 rpm, and a maximum force of 6835 g. Beckman J6-B High Capacity Centrifuge Specifications Maximum Speed 6000 rpm Maximum Speed Any speed outside the rotors critical speed range (~600 to 800rpm). Critical speed is the speed at which a rotor shifts from rotation about its center of mass. Critical Speed is characterized by some vibration. Maxium RCF 6840 x g Maximum Rotor Capacity 6 liters Driver System 1.2 kW (1 &frac12, hp) dc motor, belt-driven driveshaft. Speed Control Rotor Speed meter reading is within 50 rpm of setting on Speed dial, and within 150 rpm of actual rotor speed. Control rage is 0 to 6000 rpm. Acceleration Time Minimum 15 seconds (JA-21 rotor), maximum 2.5 minutes (JS-4.2 rotor). Braking System Electronic, variable braking Maximum Braking Time At maximum brake setting: no more than twice the acceleration time. Temperature Control Sample temperature is within 2C of the desired temperature, within 1 if calibration has also been performed. Temperature Control Range 0 to 40C at full speed, as low as -25C at reduced speed Ambient Range 16C to 38C (60F to 100F) Maximum Heat Output (During Operation) 1.9 kW (6500 Btu/h) Timer Times up to 30 minutes (60 Hz instruments) or 36 minutes (50 Hz instruments), or HOLD, graduated in 1-minute increments Rotor Chamber Diameter 580 mm (23) Electrical Requirements 3-wire single phase Range for 208V/60Hz 187-223 V Range for 240V/60Hz 224-264 V Range for 220V/50Hz 210-224 V Dimensions Right side (for tilting up door): 150mm (6) Left side:150mm (6) Back( distance from condenser fins to wall, essential for adequate ventilation):150 mm (6) Net weight: 252kg (555 lbs) Height to door top(door closed): 940mm (37). Height to work surface(door open): 910mm (35.5) Overall height: 1270mm(50) Overall width: 711mm (28) Overall depth(without bracker): 825mm (32.5) Height with door open (left side): 1600mm(63) Designed for optimal performance, the Beckman J6-B is equipped with a dynamic electric braking, high torque drive system, and three significant figures digital speed readout. To further enhance the functionalities of the J6-B system, users can integrate it with a high capacity JS-4.2 rotor with six large one-liter cups and a JS-5.2 rotor with four one-liter cups.
