SuperClear® Screw Cap Micro Tubes
SuperClear® Screw Cap Micro Tubes with molded-in elastomeric seal are ideal for any sample processing application. Excellent for frozen storage or when working with hazardous or valuable materials.
Most Screw Cap Microcentrifuge tubes are made of low quality grade resins to keep costs low. We use only high quality medical grade ultra clear resins.
SuperClear® tubes feature caps with molded in place seals that won't fall out like O-Rings supplied in other tubes. These caps can be autoclaved (122°C) and frozen (-80°C) .
Reliable Seal for Storage & Freezing
SuperClear® tubes feature a higher spin rate and USP class VI resins to ensure your work is safe and repeatable. Labcon SuperClear® Screw Cap Micro Tubes were developed using our own in-house laboratory and tested in real labs. We don't use gauges or other unrealistic testing methods.
Packed 500 in a bag and 10 bags in a pack for non sterile packages and 50 per bag and 100 bags for sterile packages. Tubes and caps are autoclavable. Tubes can be centrifuged to 20,000 RCF. And like all Labcon products the sterile versions of these tubes are packaged in medical grade bags and sterilized with a validated medical grade process to an SAL of 10-6.
SuperClear® screw cap micro tubes feature a durable wall that can withstand centrifugation to 20,000 x G. The ultra clear polypropylene resin gives you a clear view of the pellet as well as correct color rendition. Caps include our special molded in elastomeric seal that won't come loose like caps with O-rings. These caps are also easier to grip with gloves than lower quality caps.
Available in 0.5mL, 1.5mL, and 2.0mL sizes in conical base and freestanding base. These tubes fit all standard and high capacity rotors. Tubes have flat piercable caps and a side writing surface. Autoclavable and freezable for storage to -80°C.
|Endotoxin 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
These products contain resins that are processed under conditions proven to exceed the European Union standard as listed in the 22nd Commission Directive EC 98/16/EC of March 5th, 1998 as annexed to council Directive EC 76/768/EEC and further Amendment 419 Annex II of 12 June 2001.
|Medical Grade (USP)
U.S Pharmacoepia Methods and Guidelines (U.S.P Class VI) are used if applicable. We only use medical grade resins and pre-test all resins for contaminants prior to use. Resins are compliant with FDA CFR title 21-177.1520, 178.3295, 178.3297.
