UVSafe® Centrifuge Tubes


UVSafe® Centrifuge Tubes

Our Amber UVSafe® centrifuge tubes are tested and lab certified to block 100% of UV wavelengths. You can use them instead of wrapping tubes with foil. We also designed them to pass visible light so you can still see your samples.

UVSafe® tubes protect your samples but unlike the opaque black tubes others make they still allow you to see your sample. Visible light is not blocked only the UV wavelengths.

Our UVSafe® Tubes eliminate the need to wrap tubes with foil. Saving you time and your foil.

UV Blocking

Foil Saving & UV Blocking

UVSafe® tubes are available in Patented fiber racks, loose bags, or bulk. 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.


Using UVSafe® Tubes eliminates the time needed to wrap your tubes in foil. And you don't need to worry about UV wavelength leakage. Without a bulky aluminum foil wrap UVSafe® tubes fit perfectly into racks and can be clearly labeled on the frosted writing surface.

These tubes are designed to block 100% of Ultra violet light. They can be used instead of foil to shield samples sensitive to UV band radiation. They have been lab tested and certified to block UV light, but will still pass visible light so you can see your sample volume. These tubes are tested and validated to spin to 12,500 x G in most popular centrifuge rotors. Both 15mL and 50mL include a plug seal style cap with deep sealing areas. 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 a recyclable fiber rack.

Autoclavable (122°C) with caps attached. Freezable (-80°C).


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.
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)
Sterilization Validated Sterilization
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.
UV Blocking UV Blocking
Excised parts from each lot of product are placed in a spectrophotometer and examined for the ability to block transmittance of UVA, UVB and UVC wavelengths from 100-400 nm. Product lots are also tested for the ability to block transmittance of light wavelengths from 400-750 nm used in fluorescence experiments. Product lots are approved when parts demonstrate 100% blockage of all wavelengths tested.
BSE/TSE Bovine Spongiform Encephalopathy-Transmissible Spongiform Encephalopathy
