The Table Top Low Speed Large Capacity Centrifuge provides reliable centrifugal separation for high-volume laboratory applications requiring gentle processing conditions. Operating at speeds up to 5,000 rpm with maximum relative centrifugal force of 3,962 × g, this benchtop unit accommodates up to 4 × 500 ml samples in swing bucket configuration. The precision speed control (±10 rpm) and programmable timer (1 second to 99 hours 59 minutes) enable reproducible separations for routine sample preparation workflows.
Designed for continuous operation in clinical and research laboratories, the centrifuge features low noise operation (≤65 dB) suitable for open laboratory environments. Multiple rotor configurations support various tube formats including 2-7 ml blood collection tubes with capacities ranging from 48 to 72 tubes per run, making it suitable for batch processing in hematology, clinical chemistry, and cell biology applications.
How It Works
Centrifugal separation relies on the application of centrifugal force to overcome Brownian motion and gravitational settling, enabling rapid separation of particles based on density differences. When samples rotate in the centrifuge rotor, particles experience acceleration proportional to the square of rotational velocity and radius from the axis of rotation, expressed as relative centrifugal force (RCF) in units of × g.
The swing bucket rotor design allows sample tubes to orient horizontally during centrifugation, creating a longer sedimentation path compared to fixed-angle rotors. This configuration provides gentler separation conditions and cleaner interfaces between separated phases, particularly beneficial for fragile samples or when maintaining intact cellular structures is important.
Precise speed control (±10 rpm) ensures reproducible RCF values across runs, while the programmable timer enables standardized processing times. The low-speed operation up to 5,000 rpm makes this centrifuge suitable for applications requiring moderate centrifugal forces without generating excessive heat or mechanical stress on samples.

This centrifuge combines high sample capacity with precise speed control and quiet operation. The swing bucket rotor design and multiple tube format compatibility make it particularly suitable for laboratories requiring flexible, high-throughput sample processing capabilities.
Practical Tips
Verify speed accuracy periodically using a tachometer or strobe light, especially after rotor changes or if vibration is observed.
Why: Speed accuracy directly affects RCF calculations and separation reproducibility.
Clean rotor and buckets after each use with appropriate detergents and dry thoroughly to prevent corrosion.
Why: Regular cleaning prevents sample cross-contamination and extends rotor lifespan.
Always balance samples by placing tubes of equal weight in opposing positions across the rotor.
Why: Proper balancing prevents excessive vibration and mechanical stress that can damage the centrifuge.
Inspect tube integrity before centrifugation and replace cracked or damaged tubes to prevent breakage.
Why: Tube failure during centrifugation can damage the rotor and create safety hazards.
If excessive vibration occurs, stop immediately and check for proper rotor installation and sample balance.
Why: Vibration indicates mechanical problems that can cause equipment damage if not addressed promptly.
Document centrifugation parameters (speed, time, temperature) in laboratory notebooks for protocol reproducibility.
Why: Standardized documentation enables consistent results and troubleshooting of separation issues.
Allow the centrifuge to reach full speed before starting the timer for consistent separation times.
Why: Acceleration time variability can affect separation efficiency and reproducibility between runs.
Check rotor attachment and tightness monthly, especially in high-use laboratories.
Why: Loose rotor attachment can cause vibration and potential safety hazards during operation.
