Beckman Coulter L-90K Floor Ultra Speed Centrifuge

Cambridge Scientific ID #: 22286



Weight: 465 kg (1025 lb)

Height (overall): 120.7 cm (47.5 in.)

Width: 94.0 cm (37 in.)

Depth: 67.3 cm (26.5 in.)

Ventilation clearances: 5.1 cm (2 in.) sides; 15.2 cm (6 in.) rear

Maximum heat dissipation into the room: 1.0 kW (3400 Btu/hr)

Humidity restrictions: <95% (non-condensing)

Noise level measured 0.91 m (3 ft) in front of the Instrument: <57 dBa

Installation (overvoltage) category: II

Pollution degree: 2a

Revolution Counter: Displays accumulated total number of rotor revolutions in tens of thousands

Barrier Ring: 41-mm (1.63-in.) heat-treated steel alloy armor ring surrounded by a 12-mm (0.50-in.) steel vacuum chamber to provide full protection for the operator

Door: 17.5-mm (0.69-in.) high-strength structural steel

Vacuum: Diffusion pump in series with a mechanical pump typically reduces chamber pressure to below 5 microns (0.7 Pa)


  • Set speed: 1000 rpm to maximum speed in increments of 100 rpm
  • Speed control:  Actual rotor speed will be ±20 rpm of the set speed (above 1000 rpm)
  • Speed display: Indicates rotor speed in increments of 10 rpm at speeds below 1000 rpm, and increments of 100 rpm at speed above 1000 rpm


  • Set time: Up to 99 hours and 59 minutes; HOLD for runs of unspecified length
  • Time display: Indicates time remaining in timed runs, time elapsed in HOLD runs, and estimated time remaining in ω2t runs


  • Set temperature: 0 to 40°C in increments of 1°C
  • Temperature control: ±0.5°C of set temperature
  • Temperature display: Indicates rotor temperature in increments of 0.1°C
  • Temperature stability: Within 0.3°C of set after equilibration
  • Ambient temperature range: 15 to 40°C

ω2t Integrator:

  • Set ω2t: Up to 9.99 × 1014 radians squared per second
  • ω2t display: Shows accumulated centrifugal force to three significant digits (in exponential notation)

Acceleration: Selection from two profiles: maximum acceleration from 0 rpm to set speed, or slow acceleration from 0 to 500 rpm, followed by maximum acceleration to set speed

Deceleration: Selection from three profiles: full dynamic braking to 0 rpm, slow (full brake to 500 rpm followed by reduced braking to a gentle stop), or no brake

Operation: Standard, programmed, or delayed start; instrument memory can store up to nine programs

Key Switch: Used to select normal or zonal operation
