MetalFree™ Centrifuge Tubes
Our MetalFree™ centrifuge tubes are produced to ensure that key trace metals are kept below one part per billion (1ppb). They can be used for storage and analysis tasks that require extremely low levels of most common metals. These tubes are produced with a proprietary process that virtually eliminates common metals.
Far cleaner than metal free tubes offering a simple 1 part per million (1ppm) certification these tubes are unique. Developed in our own lab and using an Inductively Coupled Plasma Mass Spectroscopy (ICP) system these tubes are free of more than 20 common trace metals to a detection level of 1 part per billion.
Our MetalFree™ tubes are not only free of ultra low levels of trace metals. These tubes are also lot tested and certified free of detectable Nuclease, Endotoxin, and ATP contamination.
MetalFree™ tubes are available in our Patented fiber racks or in Loose bags. All our sterile products use medical grade packaging and are radiation sterilized following a validated ISO 11137 method to a sterility assurance level of 10-6.
Our MetalFree™ tubes are made with ultra clean resins for the tube and cap and processed to ensure that common trace metals are kept below an ICP-MS detection level of one part per billion (1ppb). These tubes are perfect for storage of samples and for applications requiring the assurance of low background metals.
All package versions are sterilized with a validated and approved ISO 11137 medical grade method to an SAL of 10-6. Racked tubes are packaged in recyclable fiber racks.
Autoclavable (122°C) with caps attached. Freezable (-80°C).
|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)
Our ultra-low metal products are tested with an ICP-MS method to confirm that the following elements fall below 1 part per billion (1ppb): Calcium, Magnesium, Zinc, Iron, Manganese, Copper, Aluminum, Silicon, Nickel, Vanadium, Sodium, Phosphorous, Cobalt, Chromium, Potassium, Lithium, Lead, Selenium, Cadmium, Mercury, and Arsenic.
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
