SuperSlik® Microcentrifuge Tubes


SuperSlik® Microcentrifuge Tubes

Our SuperSlik® snap cap microcentrifuge tubes feature an extra thick and durable wall that can withstand centrifugation to 20,000 x G. And our SuperSlik® polypropylene increases the hydrophobicity of tube surfaces so they have up to 10 times less fluid retention. So you are assured of maximum recovery of your sample.

SuperSlik® tubes feature a higher spin rate and USP class IV resins to ensure your work is safe and repeatable. And Labcon SuperSlik® Snap Cap Micro Tubes were developed using our own in-house laboratory and tested in real labs.


High Recovery & Performance

The ability to extract DNA from samples and then amplify that DNA with reliable results is an important part of lab work. SuperSlik® tubes were designed with this in mind. They can be trusted to spin at high rates. They can be opened and closed easily many times to add or remove reagents. The interior surfaces are ultra-smooth with consistent low retention performance. They are clear enough to be used in a spectrophotometer and have no extractables at the wavelength ranges you use to detect DNA.

Lab testing confirms the superior performance of SuperSlik® tubes in sample recovery. And SuperSlik® tubes are more than twice as effective at transmitting light than most brands of low retention micro centrifuge tubes.

SuperSlik® tubes feature an extra thick and 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. Designed with ergonomic caps and smooth surfaces that make this tube easy to open and can help reduce the potential for repetitive strain injury. These tubes are made from a proprietary resin that helps reduce sample hang up in the tube from viscous materials.

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.
Heavy Metal 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)
USP Metals 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)
