50 ml SuperClear CentTube, sterile packaging (100 pcs.)

Alpha Laboratories' 50ml sterile SuperClear™ centrifuge tubes are manufactured from high-quality medical grade polypropylene. Designed for more demanding laboratory applications than standard centrifuge tubes, the tubes can withstand centrifugation forces of up to 20,000g. Both the caps and centrifuge tubes are autoclavable (caps should not be autoclaved separately from tubes) and can be used within a temperature range of -90 to 122 °C. Each tube has an overall length of 115mm, an outside diameter of 29mm, and an inner diameter of 25mm.


The centrifuge tubes are lot-tested and certified free from DNA, DNase, RNase, and pyrogen/endotoxin. They are also certified as low trace metal. If the product is labeled as sterile, sterilization is achieved through gamma irradiation. The sterilisation process follows ISO 11137 sterility procedures. The thicker SuperClear™ centrifuge tube cones are manufactured using the highest quality moulds and are printed in a high-speed rotational process with reagent/chemical resistant inks. They feature large white solvent-resistant labelling areas and black easy-to-read graduations in 5ml increments with an accuracy of ± 5%. The easy-to-label flat cap design includes an integrated elastomer sealing ring. This allows the user to seal the tube with a ¾ turn to an evaporative seal. A further quarter turn makes the seal liquid-tight. This easy-grip cap design is easy to use even with gloved hands.

These centrifuge tubes are not only high-performing but are also environmentally conscious. They are made with waste-free electronic moulds that consume 40% less energy. Printing is done with no VOC pollutants. The 50ml SuperClear™ centrifuge tubes are supplied in 4 biodegradable fibre racks of 25 tubes each (100 tubes).
