Rigorous Testing Ensures Quality
Each lot of RNase-free tubes and tips are subjected to exquisitely sensitive testing for RNase contamination and are guaranteed to be nuclease free.
Ambion's standard testing calls for incubation of labeled nucleic acid in randomly sampled tubes at 37°C for 14 to 16 hours. The nucleic acid from each tube is then analyzed for degradation by polyacrylamide gel electrophoresis.
A variety of RNase- and DNase-free tubes are available. All of these tubes can be used in boiling water baths without the lids popping open.
New! 15 ml and 50 ml Conical Tubes
Ambion’s RNase-free Conical Tubes are provided assembled with green screw caps. The tubes have a printed writing space and volume marks on the sidewalls for convenience. These polypropylene tubes are sterile, nuclease-free, nonpyrogenic, and can be autoclaved to 121°C.
Microfuge Tubes
RNase-free microfuge tubes are available in three sizes, and each is marked with convenient graduations. Nonstick RNase-free tubes are useful for handling low concentrations of RNA and/or DNA because they minimize nonspecific binding to the tube.
Elution Tubes
These 2 ml tubes can accommodate RNAqueous® and Poly(A)Purist™ spin cartridges.
Dome Cap PCR Tubes
The thin-walled, dome-cap PCR tubes allow uniform contact with the thermal cycler temperature block resulting in superior well-to-tube temperature transfer and rapid cycle times.
Frosted Lid PCR Tubes
The thin-walled, flat, frosted cap provides a suitable surface for detailed labeling.
Barrier Tips
Ambion's barrier tips prevent cross-contamination of samples by means of an aerosol filter. They are RNase- and DNase-free and are ideal for handling RNA, PCR applications, and for working with radioisotopes or toxic chemicals.
Tips are compatible with Eppendorf®, Finnpipet, Oxford Benchmate®, Pipetman™ Proline®, Rainin, and Socorex pipettors.
