Refrigerated and heated centrifuges

Sigma refrigerated & heated centrifuges provide full thermal control, enabling precise separations for temperature-sensitive or viscous samples. These models support advanced workflows in biotechnology, material science, industrial testing and formulation R&D where heating improves sample flow, reduces viscosity or enhances reaction performance.

Applications – extended use cases
• Molecular biology & cell culture – improving pellet formation by reducing viscosity; protecting heat-sensitive samples using refrigeration.
• Industrial & petrochemical testing – ASTM high-temperature applications, polymer and oil analysis, viscosity-dependent separations.
• Pharmaceutical & biotech R&D – enzymatic reactions, thermal processing steps and controlled-temperature separations.
• Food, cosmetics & formulation labs – emulsion stability testing, density separation, formulation optimisation across temperature ranges.
• Nanotechnology & materials science – nanoparticle suspensions, colloid processing, aggregation studies influenced by thermal control.
