Centrifuge Tubes

Centrifuge tubes are made of high quality, crystal-clear polypropylene and designed for reliable performance in chemical and life science research. They are chloroform-resistant, leak-proof, and suitable for use with most centrifuge brands. Available in conical and round bottom styles with volumes from 0.2 ml to 150 ml, they feature a white printing area for clear labelling. The tubes are autoclavable at 121°C and freezable to -80°C, making them suitable for a wide range of sample handling steps including centrifugation, storage, and transport.

Crystal-clear polypropylene allows visual inspection of sample clarity and phase separation
Chloroform-resistant material ensures stability when handling aggressive organic solvents
Leak-proof construction prevents sample loss during high-speed centrifugation
Autoclavable at 121°C and freezable to -80°C for repeated use across thermal cycles

Comparison

Compared With The Alternatives

Versus Tubes without a printing area

The white printing area allows clear, permanent labelling without risk of smudging or fading

Versus Non-leak-proof tubes

These tubes are designed to remain sealed during high-speed centrifugation, preventing sample loss

Versus Non-autoclavable tubes

Autoclavable at 121°C allows reuse after sterilisation, reducing consumable cost in high-throughput labs

Use Guide

How To Use It

Select tube type based on sample volume and application: conical for pellet collection, round for mixing, self-standing for bench use
Use sterile tubes when working with cell cultures or sensitive biological samples
Label tubes clearly using permanent markers on the white printing area before use
Ensure tubes are balanced in the centrifuge rotor to prevent vibration or damage
For freezing, allow sufficient space for expansion and avoid overfilling

FAQ

Questions Buyers Ask

Are these tubes compatible with all centrifuges?

Yes, the tubes are designed to fit most standard centrifuge rotors and racks. Confirm compatibility with your specific model if using high-speed or ultracentrifuges.

What is the maximum temperature these tubes can withstand?

The tubes are autoclavable at 121°C and can be used at temperatures down to -80°C.

Do you offer tubes with sterile packaging?

Yes, sterile versions are available under part numbers ending in 'SA'.

Can I use these tubes for storing samples at -80°C?

Yes, the polypropylene material is freezable to -80°C without cracking or deformation.

Is the white printing area permanent?

Yes, the white area is moulded into the tube and resists fading, smudging, or peeling during use.
