Beckman J6-B High Capacity Centrifuge Specifications
Maximum Speed 6000 rpm
Maximum Speed Any speed outside the rotor’s 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 ½ 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 2°C of the desired temperature; within 1° if calibration has also been performed.
Temperature Control Range 0 to 40°C at full speed; as low as -25°C at reduced speed
Ambient Range 16°C to 38°C (60°F to 100°F)
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
