Sterile 15 mL conical tubes for labs

These sterile 15 mL conical centrifuge tubes are supplied in a pack of 500 and are designed for laboratory sample preparation and storage. The polypropylene body and polyethylene closure resist common reagents and can be autoclaved for repeated use. Graduations at 0.5 mL increments allow quick volume checks during routine protocols. They suit research, clinical and quality-control workflows that require certified sterile consumables.

Check tube dimensions and rotor ratings

Verify that your centrifuge rotors accept a 17 mm body diameter and 120 mm overall height before ordering. Confirm the maximum relative centrifugal force of your protocol does not exceed 11,000 x g, the rated limit for these tubes. Ensure your lab’s autoclave cycle is compatible with polypropylene and polyethylene materials. The tear-pack packaging should match your sterility-assurance procedures.

Thermal stability and handling in normal use

Polypropylene construction tolerates standard autoclave temperatures without deformation, supporting repeated sterilisation cycles. The secure polyethylene closure maintains seal integrity during high-speed centrifugation, reducing aerosol risk. Tubes remain stable at the rated 11,000 x g, minimising leaks or breakage that could contaminate the rotor. No active cooling or special power requirements are needed for storage or operation.
