Frequently asked questions
Does this tube handle high-speed spin rates safely?
Yes, these tubes are engineered for demanding laboratory environments and feature a maximum Relative Centrifugal Force (RCF) rating of up to 20,000 x g.
Is the material safe for sensitive biological samples?
Absolutely. These tubes are manufactured in a class 100,000 clean room and are gamma-irradiated to SAL 10-6 to ensure they are free from:
- DNase
- RNase
- Human DNA
- Pyrogens and endotoxins
Will the screw cap prevent sample leakage?
The tubes feature specialized “Easy Grip” screw caps designed with an integral seal ring. This technology provides an exceptionally secure closure to effectively eliminate seepage during processing or transport.
Are these tubes suitable for food safety testing?
Yes, the tubes are constructed from high-quality USP Class VI resin and are fully FDA CFR 21 compliant, making them suitable for food safety applications.
Is the material clear enough for accurate volume measurements?
Yes, the tubes are made from high-clarity polypropylene. For added precision, they include bold, high-contrast black graduation marks that make reading volumes quick and accurate.
Is there a designated area for labeling my samples?
Each tube comes equipped with a dedicated white marking space, providing a clear and legible area to label your samples for easy identification in the lab.
How are these tubes packaged to maintain sterility?
To ensure convenience and maintain product integrity, the tubes are supplied in heavy-duty, zip, re-closable bags.
Are these compatible with standard lab equipment?
Yes, these are standard 50 mL conical-bottom tubes designed to pair perfectly with most standard benchtop centrifuge rotors.
Does the cap design provide good tactile feedback?
The red screw caps are designed with a ribbed exterior, which provides an enhanced, ergonomic grip that makes them very easy to open and close, even when wearing gloves.
Can I use these for long-term sample storage?
Yes, the combination of high-clarity polypropylene, leak-resistant seal technology, and clinical-grade sterility makes these an excellent choice for both short-term centrifugation and long-term storage of biological materials.
