Looking for a truly easy filter tip refill? There is no need to line up tips or worry about accidental contact with TipOne filter tip refill cassettes.

Easy to Use: Each filter tip refill cassette is individually wrapped and has an easy-grip pull tab. Just unwrap the cassette, drop it into an empty TipOne rack, and remove the transfer cover.

Eco-Friendly: Refill bases and covers are #5 polypropylene and are marked for easy recycling with wafers and racks. Filter tip refills can save up to 63% of the plastic required for individual racks and 20% of the storage space.

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. TipOne RPT tips provide exceptional delivery without additives or coatings that could interact with your samples. Our tips remain safe after sterilization or autoclaving.

TipOne® filter tips have a hydrophobic filter made of ultra high-density polyethylene. Our filters contain no additives and will not absorb samples. If your sample comes in contact with the filter, it will not be sealed within the tip. You may still dispense the sample for further use. For information comparing the blocking efficiency of various filter materials, please see our application note.
