SuperClear® Round Bottom Tubes
Labcon SuperClear® round bottom tubes are precision molded with a precisely smooth round bottom, perfect for a multitude of general laboratory uses. Our round bottom tubes have thicker walls for greater strength in handling and centrifuging. These tubes are made from 100% virgin Class VI medical grade resin so you can be sure there is no contamination from the use of commodity grade plastics.
Unlike other lesser tubes our SuperClear® round bottom tubes are lot tested and certified free of detectable Nuclease, Endotoxin, and ATP contamination.
Super clear. Super strong. Super clean.
SuperClear® round bottom tubes feature a higher spin rate and USP class IV resins to ensure your work is safe and repeatable. Labcon SuperClear® Tubes work with our dual position aspirating caps, our fluted plug style caps, and our overfit caps. These tubes were developed using our own in-house laboratory and tested in real labs.
SuperClear® round bottom tubes are available in oriented pack in both sterile and non-sterile versions and in loose bags. All our sterile products use medical grade packaging and are radiation sterilized following a validated ISO 11137 medical grade method to a sterility assurance level of 10-6.
SuperClear® round bottom tubes feature an extra thick and durable wall that can withstand high centrifugation. The ultra clear resins gives you a clear view of your sample as well as correct color rendition. These tubes accept our fluted plug, aspirating, or overfit closures to ensure you have the options you need
Available in 12x75mm, 13x100mm, and 17x100mm sizes that fit all standard rotors and storage racks. Polypropylene tubes are autoclavable and freezable. Polystyrene tubes are not autoclavable.
|Endtoxin Free (Non pyrogenic)
Product samples are exposed to endotoxin-free water and the resulting extraction fluid is tested for contamination using the kinetic turbidimetric Limulus Amoebocyte Lysate (LAL) assay protocol and USP guidelines. All products tested must display less than 0.05 EU/ml to be certified free of endotoxin.
|Nuclease Free (RNase/DNase)
Product samples are exposed to nuclease-free water and the resulting extraction fluid is tested for nuclease activity on commercially available 7.5 kb Poly(A) tailed RNA (1µg) and HindIII-digested DNA (1µg) with a one hour 37°C incubation in appropriate buffers. Results are visualized on an agarose gel with appropriate positive and negative controls. Extraction fluid samples must show no degradation of the nucleic acids by the extraction fluid has occurred for the product to be certified as RNase-free and DNase-free
|Adenosine Triphosphate (ATP)
Product sample surfaces are tested for the presence of adenosine triphosphate (ATP) using a controlled bioluminescence reaction to detect contamination. Luminescence data is compared to results generated by ATP-free surfaces and surfaces with known amounts of ATP as a positive control. The relative light units result must indicate less than 2 X 10-12 mg/µl of ATP for the product to be certified as ATP free.
|Heavy Metals Free
Heavy metals have been tested for using the prescribed USP method and confirmed to have levels lower than 1 part per million (1ppm)
Labcon products are sterilized by radiation sterilization within a dose range of 12-35 kGy. The dose range necessary for the stated sterility assurance level is continuously audited through quarterly bio-burden and sterility validation studies performed according to the ANSI/AAMI/ISO 11137 standard by an independent laboratory. This dosage is sufficient to guarantee a sterility assurance level of 10-6.
|Bovine Spongiform Encephalopathy-Transmissible Spongiform Encephalopathy
