The Low Speed Refrigerated Centrifuge provides controlled centrifugal separation with precise temperature regulation for sample processing in research and clinical laboratories. Operating at speeds up to 6,000 rpm with maximum relative centrifugal force of 5,502×g, this unit accommodates up to 4×750ml sample capacity while maintaining temperature control from -20°C to 40°C with ±1°C accuracy.
The instrument features a quiet operation profile at ≤62dB and offers flexible timing control from 1 second to 99 hours 59 minutes 59 seconds including jog function. Speed precision is maintained at ±10 rpm throughout the operational range. The refrigerated design enables temperature-sensitive sample processing while the substantial 120 kg net weight provides operational stability during high-speed separations.
How It Works
Centrifugal separation operates on the principle of applying centrifugal force to overcome Brownian motion and gravitational settling, enabling rapid separation of particles based on density differences. The rotor assembly generates centrifugal acceleration proportional to the square of angular velocity and radius, creating forces up to 5,502 times gravitational acceleration to drive separation processes that would otherwise require extended settling periods.
The integrated refrigeration system maintains precise temperature control through active cooling, preventing thermal degradation of temperature-sensitive samples during extended centrifugation protocols. The temperature regulation system operates from -20°C to 40°C with ±1°C accuracy, enabling processing of samples requiring specific thermal conditions for optimal separation or preservation of biological activity.
The timing control system provides flexible operation from brief pulse centrifugation (1 second) to extended separations approaching 100 hours, with jog function capability for incremental acceleration and deceleration. Speed regulation maintains ±10 rpm precision across the operational range, ensuring reproducible centrifugal force application for quantitative separation procedures.

Practical Tips
Verify temperature accuracy monthly using a calibrated reference thermometer placed in the sample chamber during a typical protocol run.
Why: Temperature accuracy directly affects sample integrity and separation reproducibility in temperature-sensitive protocols.
Clean and inspect rotor assemblies after each use, particularly when processing samples containing proteins or other materials that may cause corrosion.
Why: Regular rotor maintenance prevents imbalance issues and extends component lifespan while ensuring safe operation.
Allow the refrigeration system to pre-cool to target temperature before loading samples, particularly for protocols requiring precise thermal control.
Why: Pre-cooling ensures immediate temperature control upon sample loading and prevents thermal shock to temperature-sensitive samples.
Use appropriate tube filling levels (typically 75-80% of tube capacity) to prevent sample spillage during acceleration and deceleration phases.
Why: Proper filling levels prevent cross-contamination and maintain sample integrity while reducing cleanup requirements.
If excessive vibration occurs, immediately stop operation and verify sample balance across all rotor positions before resuming.
Why: Unbalanced loads can damage the centrifuge mechanism and create safety hazards during high-speed operation.
Ensure the lid is fully closed and locked before initiating operation, and never attempt to open during rotation.
Why: Safety interlocks prevent accidental exposure to rotating components, which can cause severe injury at operational speeds.
Record actual operational parameters including final speed, temperature, and duration for each protocol run to ensure reproducibility.
Why: Documented parameters enable protocol optimization and troubleshooting while supporting regulatory compliance in validated environments.
