Table Top Low Speed Centrifuge - Professional Series
Benchtop low-speed centrifuge with 4000 rpm maximum speed and 2250×g RCF capacity, accommodating up to four 100ml tubes for routine sample separation applications.
The ConductScience Table Top Low Speed Centrifuge provides reliable sample separation for routine laboratory applications requiring moderate centrifugal forces. With a maximum speed of 4000 rpm and relative centrifugal force of 2250×g, this benchtop unit accommodates up to four 100ml containers in its angle rotor configuration. The instrument operates with ±10 rpm speed precision and maintains noise levels at or below 60 dB(A) for comfortable laboratory environments.
Designed for continuous operation or timed runs from 1 second to 99 minutes 59 seconds, the centrifuge features short-span capability for brief applications. The compact footprint (340×470×280mm) and 18kg weight make it suitable for standard laboratory benches while providing the separation performance needed for sample preparation, cell pelleting, and clarification procedures across multiple research disciplines.
How It Works
Centrifugal separation operates on the principle of differential sedimentation under applied centrifugal force. When samples are spun at high rotational speeds, particles experience forces many times greater than gravity, causing components with different densities to separate based on their sedimentation coefficients. The angle rotor design positions tubes at a fixed angle relative to the rotation axis, creating both radial and tangential force components that facilitate efficient pelleting.
The relative centrifugal force (RCF) is calculated as 1.118 × 10⁻⁵ × r × N², where r is the radius from the center of rotation to the sample and N is the rotational speed in rpm. At maximum speed of 4000 rpm, this centrifuge generates 2250×g, sufficient for most routine separation tasks including cell harvesting, precipitate collection, and sample clarification.
Timing control allows for optimization of separation conditions based on particle size and density differences. Short-span mode enables brief spins for delicate samples, while continuous operation supports extended separations for challenging applications requiring prolonged centrifugal force.

Practical Tips
Verify speed accuracy periodically using a tachometer or strobe light, especially after transportation or heavy use.
Why: Speed accuracy directly affects RCF calculations and separation reproducibility.
Clean rotor and chamber after each use with mild detergent, and inspect rotor for cracks or wear monthly.
Why: Regular cleaning prevents cross-contamination and early detection of wear prevents catastrophic failure.
Always balance samples within 0.1g across opposing positions and use balance tubes when running odd numbers of samples.
Why: Proper balance prevents excessive vibration that can damage bearings and affect separation quality.
Pre-cool samples and tubes when working with temperature-sensitive materials to minimize heat generation during spinning.
Why: Centrifugation generates heat that can denature proteins or affect cell viability in biological samples.
If excessive vibration occurs, immediately stop and check sample balance, tube integrity, and rotor installation.
Why: Unbalanced loads can damage drive mechanisms and create safety hazards from excessive vibration.
Record actual run times and speeds in protocols rather than relying solely on programmed settings for reproducibility.
Why: Slight variations in timing or speed can affect separation outcomes and experimental reproducibility.
Never open the lid while the rotor is spinning and wait for complete stop before accessing samples.
Why: Moving rotors present serious injury risk and samples may still be settling even after deceleration begins.
Replace rotor according to manufacturer specifications based on accumulated run time and visual inspection.
Why: Metal fatigue from repeated stress cycles can lead to rotor failure with potentially catastrophic consequences.
