Refrigerated vs. Non-Refrigerated Centrifuges: Which Does Your Lab Need?

The single most common question we receive from distributors and lab managers: do I really need the refrigerated version? The answer depends on your samples, your run times and your quality requirements.

What refrigeration actually does

A refrigerated centrifuge integrates a compressor and CFC-free refrigeration loop around the chamber, typically holding -20 °C to +40 °C within ±1–2 °C regardless of rotor speed. Without it, air friction and motor heat raise chamber temperature — a 30-minute high-speed run can push samples 10–15 °C above ambient.

When refrigeration is essential

• Proteins, enzymes, antibodies — activity degrades with heat; protocols often mandate 4 °C.
• Live cells and PRP — viability and platelet quality depend on stable temperature.
• Blood banking and clinical samples — standards and accreditation frequently require temperature-controlled separation.
• RNA/DNA workflows — nucleases are less active at low temperature, protecting yield.

When a non-refrigerated model is fine

• Routine serum/plasma separation with robust analytes
• Short spins (under 10 minutes) at moderate speed
• Teaching labs and QC of heat-stable materials
• Tight budgets where a cooled room already limits heat build-up

Total cost of ownership

Refrigerated models cost more up front and consume more power, but they protect sample integrity — and re-running a ruined batch costs far more than the electricity saved. For clinical, biopharma and research customers, we generally recommend refrigerated; for teaching and basic QC, a well-built ventilated model is the economical choice.
