Centrifuges

Pharma+ Centrifuge Range

Designed by analytical chemists and laboratory scientists, with over 25 years of centrifuge manufacturing behind it. Capacities run from micro to 4 litres, all with bright blue touch screen LCD displays and ω²t as standard for full run repeatability. All centrifuges and rotors carry a 2-year warranty.

  • Through Flow Air System: keeps samples and motor cool in ambient models, allowing longer run times.
  • Dynamic Efficiency Control refrigeration: compressor hot-gas bypass with PID valve control holds set temperature to 0.5°C, compared with 3.5°C for on/off controlled competitors, while cutting power use by 25%.
  • Rotors built for chemical resistance: salt-saturation tested stainless steel bowls, CNC-machined polypropylene fixed-angle rotors, and double-anodised aircraft-grade aluminium swing-out and high-speed rotors.
  • Operator features: rotor recognition, 10 acceleration and 10 deceleration rates, 99 program memory, pulse short run, speed in rpm or RCF in 1 rpm steps, sound below 60 dB.
  • Safety: multi-point lid locking, emergency lid release, lid lock and imbalance detection, overspeed sensor, barrier ring, and motor overheat sensor.
  • Class 3 containment: hermetically sealable rotor buckets are available for work in Class 3 containment areas.

Rotor Selection Guide

Fixed-angle rotors spin samples down fastest; swing-out rotors suit separations that need a flat pellet or layer. Rotors are autoclavable at 121°C.
