TipOne? racks have a contoured lid and base for easier handling. Tip volume, lot number, and other important information is laser-marked on the front of each wafer - no label required!

TipOne? RPT ultra low retention tips use the best available technology to optimize polypropylene tip surfaces, improving the flow dynamics of viscous liquids and other difficult samples.

Molded polypropylene exhibits a microscopically uneven surface that can effect the movement of fluids with low surface tension. All precautions are taken to minimize this effect during TipOne production. Now, TipOne RPT takes this a step further by creating an extremely uniform and stable surface that eliminates any hold up of liquids during pipetting.

In contrast to other technologies that use siliconized or fluoro-coated surfaces to smooth out polypropylene, TipOne RPT tips offer exceptional delivery without the risk of interaction with additives or treatments, even after sterilization or autoclaving. All tips have the same engineered fit as original TipOne and are certified free of detectable RNase, DNase, DNA, and pyrogens.

While our original TipOne pipet tips are recommended for almost all laboratory procedures, there are applications where it can be beneficial to use TipOne RPT. Examples include selected nucleic acids and proteins, viscous liquids, and solutions with Triton-X, glycerin, or other components that require an extremely low surface energy for complete sample release. TipOne RPT will also ensure optimum delivery of aqueous and other common laboratory solutions.
