The ConductScience Low Speed Centrifuge Machine operates at variable speeds up to 4000-5000 rpm, designed for routine laboratory separations in research environments. This benchtop centrifuge accommodates 20ml sample capacity with insert compatibility for 15ml, 10ml, and 5ml vacuum tubes. The unit features a maximum insert size of 18.5 x 113mm, providing flexibility for various tube types commonly used in laboratory protocols.
The centrifuge employs centrifugal force to separate components of biological and chemical samples based on density differences. At the specified speed ranges, this instrument generates sufficient relative centrifugal force (RCF) for pelleting cells, precipitating proteins, and clarifying solutions. The economical design maintains essential functionality while providing reliable performance for routine laboratory separations.
How It Works
Centrifugal separation operates on the principle that particles of different densities sediment at different rates when subjected to centrifugal force. The rotor assembly spins sample tubes at controlled speeds, generating centrifugal acceleration that causes denser particles to migrate toward the bottom of the tube while lighter components remain in the supernatant.
At speeds of 4000-5000 rpm, the centrifuge generates relative centrifugal force (RCF) values that effectively separate cellular materials, precipitates, and particulates from solution. The separation efficiency depends on particle size, density differential, and centrifugation time. Larger, denser particles require lower speeds and shorter times, while smaller particles may require maximum speed and extended centrifugation periods.

Practical Tips
Always balance tubes by weight, not just volume, placing equal masses in opposite positions.
Why: Proper balance prevents excessive vibration that can damage the rotor and affect separation quality.
Clean the rotor and chamber after each use, especially when processing biological samples.
Why: Residual material can cause corrosion and contaminate subsequent samples.
Never open the lid until the rotor has completely stopped and the safety lock disengages.
Why: The spinning rotor poses injury risk and sudden deceleration can disturb separated phases.
Verify speed accuracy periodically using a tachometer or strobe light.
Why: Speed accuracy affects the reproducibility of centrifugal force and separation results.
If excessive vibration occurs, stop immediately and check tube balance and rotor installation.
Why: Imbalanced loads can damage bearings and create safety hazards.
Record actual centrifugation conditions (speed, time, temperature) for protocol reproducibility.
Why: Complete documentation enables troubleshooting and ensures consistent results across experiments.

Compliance
What is the maximum relative centrifugal force (RCF) achievable at 5000 rpm?
The maximum RCF depends on the rotor radius. Consult the product datasheet for specific RCF calculations based on the rotor dimensions provided with the unit.
Can this centrifuge accommodate microcentrifuge tubes?
The unit is designed for 15ml, 10ml, and 5ml vacuum tubes with maximum insert size of 18.5 x 113mm. Compatibility with 1.5ml microtubes would require appropriate adapters if available.
What is the typical acceleration and deceleration time?
Specific acceleration and deceleration profiles are not provided in the basic specifications. Consult the technical manual for complete performance characteristics.
Is temperature control available during centrifugation?
This economical model does not specify temperature control features. Heat generation during operation may occur with extended high-speed runs.
What maintenance is required for reliable operation?
Regular cleaning of the rotor and chamber, periodic inspection of rotor balance, and verification of speed accuracy are recommended. Specific maintenance intervals should follow manufacturer guidelines.
Can the rotor be autoclaved for sterilization?
Rotor sterilization compatibility depends on construction materials. Consult the product manual for approved sterilization methods and temperature limits.
