Are these tubes compatible with standard centrifuge rotors?
Yes, the 15 mL and 50 mL formats are designed to fit standard laboratory centrifuge rotors.

Are these tubes suitable for molecular biology applications?
Yes, they are suitable for DNA/RNA extraction, protein precipitation and other molecular biology workflows.

Can the tubes be used for freezing samples?
Yes, they can be used down to –80°C. The recommended maximum fill line should be respected when freezing.

Do the tubes have volume graduations?
Yes, they feature solvent-resistant printed graduations with a reverse scale for easier volume reading.

Are these tubes autoclavable?
Autoclaving is possible, but caps should be loosened or removed before the cycle.

Are the tubes leak-proof?
The screw caps include an internal sealing ring designed to ensure secure closure and minimize leakage risk.
