• Holds more volume for better performance with 300 µl multichannel pipettes
• Graduated at 100 µl, 200 µl, and 300 µl
• Ultra low retention improves the flow dynamics of viscous or difficult liquids
• Hinged racks with 96 tips
• Compatible with most multi-channel pipettes
• Raised rims on lid for easy stacking & storage
• Orange wafer color indicates low retention
• Certified free of detectable RNase, DNase, DNA and pyrogens

Even when full, TipOne® 300 µl pipet tips provide plenty of clearance between the pipette tip cone and your sample. The extra space helps prevent accidental tip cone contamination and provides more security if the pipette is angled during use.

300 µl TipOne tips fit ErgoOne® and a wide variety of pipettes from Biohit, Eppendorf, Gilson, Thermo, and other companies. Contact us for a sample if you would like to try this tip in your lab.

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!

Sturdy racks have a one-piece base that resists tipping during use. The transparent, hinged lid remains open at 120° for easy single or multi-channel pipettor access. If you prefer a non-hinged, lift-off lid, simply remove the lid from the hinges, turn the opening clasp toward the back, and place the lid back on the rack.

Both the lid and the base withstand repeated autoclaving. The two-position latch allows the lid to be shut tightly or kept slightly ajar for more effective autoclaving.

All tips are packaged in boxes of ten racks. They are also available sterilized. The rack is compatible with most multi-channel pipettes and will not flex or tip over during use. Each rack can be easily refilled with pre-loaded, snap-in tip wafers (reload).

TipOne RPT Ultra Low Retention Technology

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.

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.
