SuperClear® Tubes with FILTROX® Filters


SuperClear® Tubes powered by FILTROX®

SuperClear® tubes with a FILTROX® PURASPIN® insert create a centrifugal spinner that performs efficient and cost effective depth filtration for a multitude of bench top applications. These devices are adaptable to your small scale filtration needs and allow for centrifugal as well as vacuum filtration with the included luer lock.

Available in six standard filter densities offering a range of possible filtration from coarse to sterile.

Flow Cytometry

Easy Sample Filtration

SuperClear® Tubes with FILTROX® PURASPIN® inserts are easy to use and come with all that is needed. No additional components or fittings are required. Available in filter retention rates from 30µm to 0.1µm for a wide range of filtration needs.

In pre-assembled packages of 10 tubes.

The SuperClear® tube with FILTROX® PURASPIN® is an ultra high performance centrifuge tube and cap combination that includes a removable FILTROX® funnel insert. The funnel insert includes a FILTROX® filter medium available in various formats and a nossle that can be fitted to a luer locking syringe or hose. The cap keeps the FILTROX® spinner securely in place with its unique elastomeric seal. The entire assembly forms a neat package that can be disposed of after use. Both the tube, cap, and spinner are made of USP Class VI resin.



SuperClear® tubes with FILTROX® PURASPIN®inserts are easy to use. Making the tedious job of filtering samples easy.

Available in boxes of 10 assembled tubes.

Endotoxin 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.
RNase/DNase 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
ATP 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.
