50 ml centrifuge tubes, which are also known as conical tubes, are a staple laboratory consumable used for the separation, storage, and processing of biological or chemical samples. These tubes are fabricated from high clarity polypropylene (PP) and, like all conical tubes, offer good chemical resistance. They can also withstand high speed centrifugation (12,000 x g max, depending on model), which is a common requirement for laboratory tubes. Each tube has clear graduation markings, a large white section for writing, and a cap that, when closed, is leak-proof. This guarantees that samples are stored safely without the risk of contamination.

Advantages of Our 50 ml Centrifuge Tubes 

● The centrifuge tube is leak-proof with a reinforced screw cap which guarantees no sample loss during centrifugation.

● The tubes are also sterile, DNase (deoxyribonuclease)/RNase (ribonuclease) free, pyrogen free which makes them ideal for sensitive molecular biology or clinical diagnostics.

● High speed centrifuge resistance which can withstand forces up to 12,000 x g.

● Easy sample visibility and tracking due to the tubes’ crystal-clear transparency.

● The tube is easy to use and ergonomically designed with a Gentle rim and easy-grip cap which makes using the tube with gloves effortless.

● Accurate graduations to within ± 2% for strict laboratory measurement requirements.
