Frequently Asked Questions About 15ml Centrifuge Tubes
Can I autoclave 15ml centrifuge tubes multiple times?
Most polypropylene 15ml centrifuge tubes can be autoclaved 2-3 times at 121°C before showing signs of degradation, but always check manufacturer specifications for exact limits. Tubes and caps may be frozen at temperatures as low as -86°C, indicating good thermal stability. However, repeated autoclaving may compromise structural integrity.
What’s the difference between conical and round-bottom 15ml tubes?
Conical 15ml tubes provide better pellet formation and easier sample recovery with reduced dead volume, while round-bottom tubes offer traditional design compatibility with older centrifuge systems. Conical 15mL and 50mL centrifuge tubes are made of premium polypropylene for clarity and centrifugal strength. Therefore, conical designs have become the preferred choice for most applications.
Are all 15ml centrifuge tubes leak-proof?
Not all 15ml centrifuge tubes are leak-proof; only tubes specifically tested and certified for pressure resistance can claim leak-proof performance up to specified pressures. The C2600 series of centrifuge tubes are leak-proof to 95 kPa/14psi. Moreover, cap design significantly impacts sealing effectiveness.
How do I choose between sterile and non-sterile 15ml tubes?
Choose sterile 15ml tubes for cell culture, molecular biology, and clinical applications; select non-sterile tubes for routine chemistry work, storage, and applications where sterility isn’t critical. Sterile tubes are RNase, DNase, pyrogen and cytotoxin free. Additionally, sterile options cost 20-40% more than non-sterile alternatives.
What’s the maximum sample volume for 15ml centrifuge tubes?
Fill 15ml centrifuge tubes to maximum 12ml (80% capacity) to prevent overflow during centrifugation and allow for sample expansion during processing. The maximum centrifugal force is 12,000×g for the 15mL tubes, requiring adequate headspace for safe operation. Furthermore, overfilling can cause tube failure and contamination.
Which brands offer the best warranty on 15ml centrifuge tubes?
Premium brands like Corning and CELLSTAR typically offer quality guarantees and replacement policies for defective tubes, while budget brands may have limited warranty coverage. Choose from economical clinical line to sophisticated RNase/DNase free research line based on your risk tolerance. Therefore, consider warranty terms when comparing total cost of ownership.
Conclusion: Making the Smart Choice for Your Lab
Selecting the right 15ml centrifuge tubes significantly impacts your laboratory’s efficiency, results quality, and budget management.
