Benchtop centrifuge with cooling Digicen 21R, Orto Alresa

The centrifuge refrigerated Digicen 21R can reach up to 24.959 xg with a wide range of rotors:

  • Swing out rotors, with a max volume of 4 x 100 ml which can fit several set of adapters 
    for tubes with or without caps, microtubes, microplates.
  • Angle fixed low speed for routine purposes.
  • Angle fixed high speed from microtubes to 50 ml conical tubes.

On LCD screen shown the selectable values as time, RPM, RCF, temperature and braking time as well as graphics for lid open, progress bar, and acoustic signals for a better control about the process by operator.

The powerful refrigeration system, enhanced by the pre-cooling program, keep the samples at stable and controlled temperature, avoiding sample´s temperature fluctuations at introducing into the device.

Stabilizing sample preparation.
