Beckman Coulter Microfuge 22R Common Applications and Refrigerated vs. Non-Refrigerated Operation

The Beckman Microfuge 22R is commonly used for DNA and RNA extraction, plasmid purification, PCR cleanup, protein precipitation, enzyme preparation, microbiology research, molecular diagnostics, cell lysate clarification, and routine molecular biology workflows.

Its refrigerated chamber maintains low sample temperatures throughout centrifugation, helping preserve nucleic acids, enzymes, proteins, and other temperature-sensitive biological materials. Compared with a non-refrigerated microcentrifuge, the Microfuge 22R provides superior sample protection during extended or high-speed runs.

Beckman Coulter Microfuge 22R Rotor Compatibility and Included Accessories

Rotor flexibility is one of the advantages of the Beckman Microfuge 22R platform.

This particular centrifuge includes:

24-place rotor for 1.5 mL / 2.0 mL microcentrifuge tubes
Rotor lid
Power cord

The included rotor is ideal for:

DNA extraction
RNA purification
Plasmid preparation
PCR cleanup
Protein precipitation
Enzyme preparation
Routine molecular biology
Clinical research

The Beckman Microfuge 22R platform is also compatible with additional fixed-angle, swinging bucket, and PCR strip rotors, allowing laboratories to expand the instrument's capabilities as their workflows evolve.

Customers should verify included rotors prior to purchase, as centrifuge configurations can vary between systems.
