Common Applications of Laboratory Centrifuges

Centrifugation is widely used in laboratories for separating particles suspended in solutions based on density. Some key applications include sedimentation of cells, viruses, and organelles, isolating DNA, RNA, proteins and lipids, and separating blood components like serum from whole blood Thermo Fisher Scientific. Tabletop centrifuges are commonly found in diagnostic labs, hospitals, biotech facilities for various separating procedures.

Installation Requirements

To ensure optimum performance, centrifuges must be placed on a sturdy, level surface allowing adequate clearance and away from heat sources or windows. Follow manufacturer guidelines for electrical, environmental, and loading requirements. Inspect rotors for damage and clean drive shafts before use. Only load rotors symmetrically to maintain balance.

Safe Operation Procedures

Always secure rotors tightly, do load more than recommended, and inspect tubes for cracks. Use safety cups with infectious samples. Monitor for unusual noises and wait until full speed is reached before leaving. Close lids during runs and wait 10 minutes after stopping before opening Lab Manager.

Routine Maintenance Tasks

Maintenance such as cleaning, lubrication, inspection prevents inefficiencies and hazards. Follow the schedule provided in Table 1 for tasks before, after, and yearly. Perform calibration testing annually and sterilize contaminated parts according to guidelines.

Recommendations for Safe Practices

Some tips include using plastic instead of glass tubes, properly fitting tubes in adapters, and handling samples in a biosafety cabinet. Wait 30 minutes after a spill and decontaminate immediately with bleach or ethanol solutions.

When Accidents Occur

If a tube breaks during operation, wait at least 30 minutes before opening to allow aerosols to settle. Notify appropriate personnel and follow spill response procedures. Incidents must be properly documented and reviewed to prevent future accidents.

Choosing the Right Centrifuge Tubes from Esco
