We test every lot of these tubes at a much higher g-force than we rate them to ensure that you can spin them safely at the higher speeds your lab may need to accomodate. Our quality control team tests the seals with chloroform to ensure caps are leak-proof. So these don't just look like centrifuge tubes, they really are.
These tubes are made from a unique medical grade resin that is far more durable than commodity grade resins used in most popular brands of tubes.
Spin rates much higher than most popular brands (Superclear
® up to 20000 RCF); Fits into most standard size centrifuge rotors
Elastomeric polyethylene caps in select options that prevent leaking - Freeze to -80
Clear graduations and resin allow for accurate sample observation
Resin is pre-tested to ensure no extractables are present. Every lot is lab tested and certified free of detectable Nuclease (Rnase/Dnase), Adenosine Tri-phosphate, and Endotoxin (pyrogen) contamination.
