The High Speed Refrigerated Centrifuge is a high-capacity laboratory instrument designed for temperature-controlled separation applications requiring substantial rotor volumes and precise speed control. This benchtop unit operates at speeds up to 21,000 rpm with maximum relative centrifugal force of 47,580×g, accommodating up to 4×750ml sample volumes per run. The integrated refrigeration system maintains sample temperatures from -20°C to 40°C with ±2°C accuracy, essential for preserving temperature-sensitive biological materials during extended centrifugation protocols.

The centrifuge features digital speed control with ±30 rpm precision and programmable timing from 1 minute to 23 hours 59 minutes. Sound dampening reduces operational noise to ≤65dB, suitable for standard laboratory environments. The substantial 252 kg net weight provides operational stability during high-speed runs, while the compact 825×625×910mm footprint fits standard benchtop configurations.

How It Works

Centrifugal separation exploits differences in particle density, size, and shape by subjecting samples to controlled gravitational forces. The centrifuge rotor accelerates samples in a circular path, generating centrifugal force proportional to the square of angular velocity and radius from the rotation axis. Denser particles migrate outward faster than lighter components, enabling separation based on sedimentation coefficients.

The integrated refrigeration system circulates coolant through the rotor chamber, maintaining precise temperature control during operation. This prevents thermal denaturation of proteins, maintains enzyme activity, and preserves sample integrity during extended protocols. Variable speed control allows optimization of separation conditions for different sample types, from gentle pelleting of fragile cells to high-force clarification of dense suspensions.

Digital timing and speed controls enable reproducible protocols with precise control over separation parameters. The microprocessor monitors rotor speed, temperature, and elapsed time, automatically terminating runs when programmed conditions are met while maintaining safe deceleration profiles.
