50 ml APEX Essential CentTube, loose, sterile (2 x 50 pcs.)

Alpha Laboratories 15ml APEX® Essential sterile centrifuge tubes are manufactured from high-quality, medical-grade polypropylene. Designed for everyday centrifugation and storage requirements, the tubes can withstand a centrifugation force of up to 12,500 x g. Both the caps and centrifuge tubes are autoclavable (caps should not be autoclaved separately from the tubes) and can be used in a temperature range of -90 to 122 °C. Each tube has an overall length of 118mm, an outer diameter of 17mm, and an inner diameter of 15mm.


The centrifuge tubes are lot-to-lot tested and certified free from DNA, DNase, RNase, and Pyrogen/Endotoxin. They are also certified to be low in trace metals. Where the product is labelled sterile, sterilisation is by gamma irradiation. The sterilisation process follows ISO 11137 sterility procedures. APEX® Essential centrifuge tube cones are produced using the highest quality molds and printed at 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 0.5ml increments accurate to ±5%. The easy-to-cap flat-top cap design allows the user to seal the tube with a ¾ turn with 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 not only perform but are also environmentally friendly. They are manufactured using waste-free electronic molds that consume 40% less energy. Printing is done without VOC pollutants. The 15ml APEX® Essential centrifuge tubes are supplied bulk in 2 packs of 50 tubes.
