Application

Our plastic centrifuge tubes are universal disposable lab consumables compatible with most centrifuges, widely applied across multiple fields:
●Clinical medical laboratories: Process blood, urine and other patient specimens for routine diagnostic testing
●Biochemistry research: Conduct solution stratification, precipitation and centrifugal separation of chemical reagents
●Molecular biology labs: Store nucleic acid, protein samples for gene extraction, amplification and related experiments
●Academic & pharmaceutical research: Sample dilution, temporary preservation and liquid transfer in trial tests

Operation Steps
Sample loading: Transfer liquid samples into our plastic graduated centrifuge tubes, never fill past the printed max graduation to avoid overflow during centrifugation.
Sealing: Fully tighten the matched screw cap of our 10ml/15ml/50ml tubes for reliable leak-proof performance.
Balancing: Prepare two Guide Medlab centrifuge tubes with equal weight and place them oppositely on the rotor to reduce vibration.
Centrifuging: Adjust rotation speed and runtime following your lab test requirements, then launch the centrifuge.
Post-operation: Wait for the rotor to halt entirely before taking out the tubes to keep separated samples intact.
