Filtered Pipette Tips

Protect Against Cross-Contamination

Unlike other filter types that contain additives that can inhibit enzymatic reactions, Rainin filtered pipette tips are made from pure virgin sintered polyethylene. Hydrophobic polyethylene particles prevent aerosols and liquids from being aspirated into the body of the pipette.

The filters are machine-loaded to assure that tips remain completely untouched during manufacturing and packaging. They are certified free of RNase, DNase, DNA, and pyrogen contamination. In addition, all filter tips are pre-sterilized by radiation after packaging as added protection for biological samples.

Filtered pipettes tips are available for LTS and universal-fit pipettes.

Filter Tip Volumes and Styles

"Torturous Path" Aerosol Barrier

Aerosol resistant tips use a filter which is manufactured from sintered polyethylene. This processes a “torturous path” aerosol barrier.

 
Rainin filters have an average pore size of 40 microns. This pore size is considered “less restrictive” and doesn’t detectably increase resistance or affect pipetting accuracy.

Rainin Certified

Filtered pipette tips are guaranteed to produce accurate and precise measurements when used with Rainin pipettes and in accordance with their instruction manuals.

 
Rainin Certified Filter tips meet or exceed minimum standards for:

• Absence of flash
• Absence of contamination
• Surface smoothness and regularity
• Delivery end geometry, dimensions and finish
• Pipetting accuracy (unconventional geometries lead to deviations)

FinePoint

FinePoint tips taper to a fine orifice diameter. Their slender design, in combination with thin, flexible walls, creates an exceptionally supple tip that assists in sample touch-off. The narrow orifice aperture and thin wall surrounding the orifice provides minimal surface area for residual sample to adhere to during sample dispensing. FinePoint tips discharge completely for optimal pipetting accuracy.

Many Sizes, Styles and Packaging Options

Rainin filtered pipette tips are available in many tip styles and sizes, for universal-fit pipettes. They come in a selection of packaging options such as racks, GreenPak, SpaceSaver and bulk.
