Product Q&A

Q:What is the key advantage of a conical-bottom design?
A:
The conical bottom forces solids to concentrate into a tight pellet at the very tip during centrifugation. This makes it extremely easy to decant or pipette the supernatant away with minimal risk of disturbing the pellet, maximizing sample recovery.
Q:How do I know if a bottle is rated for my centrifuge's speed?
A:
Always check the manufacturer's specifications for the maximum allowed Relative Centrifugal Force (RCF or g-force) for the bottle. Never exceed this rating. The bottle's material, design, and cap system determine its speed capability, and using an under-rated bottle is a safety hazard.
Q:What should I do if my bottle becomes scratched or hazy?
A:
Retire it immediately. Scratches and cloudiness indicate material fatigue and compromised structural integrity. Stresses can focus at these points, dramatically increasing the risk of bottle failure (cracking or implosion) during a spin.
Q:How do I properly clean these bottles?
A:
Rinse thoroughly with an appropriate solvent or detergent immediately after use. Use a soft bottle brush if necessary, but avoid abrasive scrubbing that can cause micro-scratches. Always allow them to dry completely before storage.
