15 ml SuperClear CentTube, loose, non-sterile (100 pcs.)

Alpha Laboratories non-sterile 15ml SuperClear™ centrifuge tubes are manufactured from high-quality, medical-grade polypropylene. The tubes are designed for more demanding laboratory applications than standard centrifuge tubes, able to withstand up to 17,000 x g of centrifugal force. Both 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 118mm, an external diameter of 17mm, and an internal diameter of 15mm.


The centrifuge tubes are batch-tested and certified to be free of DNA, DNase, RNase, and pyrogen/endotoxin. They are also certified to be trace metal-free. If the product is labelled sterile, sterilization occurs through gamma irradiation. The sterilization process follows ISO 11137 sterility procedures. The thicker SuperClear™ centrifuge tube cones are manufactured using the highest quality molds and are printed using a high-speed rotational process with reagent/chemical-resistant inks. They feature large white solvent-resistant labelling areas and black, easy-to-read graduations at 0.5ml increments with an accuracy of ± 5%. The easy-to-label flat cap design allows the user to seal the tube with a ¾ turn with an evaporative seal. Another quarter turn makes the seal liquid-tight. This easy-grip cap design is easy to use even with gloves.

These centrifuge tubes not only excel in performance but are also environmentally friendly. They are produced using zero-waste electronic molds that use 40% less energy. Printing is performed without VOC pollutants. The 15ml SuperClear™ centrifuge tubes are supplied in bulk in 2 packs of 50 tubes.
