Beckman Avanti J-20XP Centrifuge, 26,000 rpm In Ramsey, MN, USA (CAT#: STEM-LCPO-0295-YJL)

Beckman Avanti J-20XP Centrifuge, 26,000 rpm In Ramsey, MN, USA, model Beckman - Coulter Avanti J-20, is manufactured by Beckman - Coulter laboratory centrifuges.
The Beckman Avanti® J-20XP is a large-volume solution designed to increase laboratory throughput. This Beckman centrifuge is versatile enough to perform a wide variety of applications which require the use of DNA microplate carrier kits, elutriation systems, and other larger volume and high-speed rotors.
The Beckman Avanti® J-20XP centrifuge generates up to 26,000 rpm and 82,000 x g. The centrifuge system is the first high performance centrifuge series that can accommodate six 1-liter bottles at forces up to 16,800 x g. The J-20XP centrifuge is also compatible with 3-liter and 4-liter swinging bucket rotors, and even with rotors that can accommodate up to 24 microplates.
As part of the series, the Beckman Avanti® J-20XPI centrifuge has all the features of the J-20XP.

Condition: Used
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; 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”)
