Laboratory centrifuges in Jordan
A laboratory centrifuge separates samples by spinning them at a set speed, and the number that matters is relative centrifugal force (RCF, in x g), not RPM. Choose it by the largest tube you will spin, the RCF your protocol needs, and whether samples must stay cooled.

How to choose: Laboratory centrifuges
- 01
RCF, not RPM
Protocols specify x g. The same RPM gives different force in different rotors, so check the maximum RCF of the rotor you will actually use.
- 02
Capacity and tube format
List your tubes (0.2 mL strips to 500 mL bottles) and the batch size. One versatile rotor set often saves buying a second machine.
- 03
Refrigeration
Refrigerated models hold 4 °C or lower for proteins, blood products and enzymes, and stop rotor heating on long, fast runs.
- 04
Rotor type
Swing-out rotors suit pelleting and gradients; fixed-angle rotors reach higher speeds and spin faster for small tubes.
- 05
Safety and compliance
Look for imbalance detection, lid lock, aerosol-tight lids for infectious samples, and rotor-life tracking.
Typical applications
- Clinical and blood-bank laboratories
- Molecular biology: DNA/RNA extraction and PCR prep
- Microbiology and cell culture
- Pharmaceutical quality control
- University teaching laboratories

Frequently asked questions
What is the difference between RPM and RCF?
RPM is rotor speed. RCF is the force the sample experiences and depends on both RPM and rotor radius: RCF = 1.118 × 10⁻⁵ × radius (cm) × RPM². Use RCF when comparing machines or following a protocol.
Do I need a refrigerated centrifuge?
Yes if you work with proteins, enzymes, live cells or blood products, or run long high-speed cycles. For routine clinical tubes at moderate speed an ambient benchtop model is usually enough.
Does Al-Shaker install and service centrifuges in Jordan?
Yes. The same technical team that specifies the centrifuge installs it, trains operators and offers maintenance contracts, including rotor inspection and speed verification.
