• Sterile tubes have attached blue screwcap
• Black printed graduations in 0.25mL increments
• White printed writing space
• Autoclavable (without caps)

Global scientific 50ml Centrifuge tubes self Standing Skirted flat cap are manufactured using high quality, medical grade polypropylene. The tubes have been designed for everyday centrifugation and storage needs and can withstand a centrifugation force of up to 9000g. Both the caps and the centrifuge tubes are autoclavable (caps should not be autoclaved separately from tubes) and can be used within a temperature range of -90 to 122C. Each tube has an overall length of 115mm, an external diameter of 29mm.

The centrifuge tubes are lot by lot tested and certified DNA, DNase, RNase and Pyrogen/Endotoxin free. They are also certified low in trace metals. Where product is marked sterile, sterilisation is by Gamma irradiation.

The sterilisation process follows the ISO 11137 procedures for sterility. Global Scientific centrifuge tube cones are produced using the highest quality moulds and are printed using a high speed rotary process that employs reagent/chemical resistant inks. They include large white, solvent resistant labelling areas and black, easy to read graduations in 0.5ml increments that are accurate to ± 5%. The easy to label flat-cap design enables the user to seal the tube to an evaporation seal with a ¾ turn. A further ¼ turn will make the seal liquid tight. This easy-grip cap design is simple to use, even when wearing gloves.

These centrifuge tubes not only excel in performance but are environmentally responsible. They are manufactured using waste-free electronic moulds that use 45% less energy. Printing is carried out without VOC pollutants.
