Wide Orifice Pipette Tips

Protect Delicate Samples

A wide bore (wide-orifice) pipette tip makes it easier for liquids to flow in and out of the tip. A wider opening helps minimize shear force, protecting delicate samples like DNA/RNA samples and cells and easing work with high-viscosity liquids like pure glycerol. Wide bore tips from Rainin are available with low-retention coating to cleanly and accurately pipette sticky and viscous samples. BioClean Ultra™ wide orifice tips are available as both filtered and non-filtered.

Advantages of Wide-Orifice Pipette Tips

Wide Orifice Pipette Tips

Reduce Shear Force and Resistance

Wide-orifice tips, also known as wide-bore pipette tips, have larger apertures to reduce shear force and provide a larger opening for aspirating and dispensing viscous, particulate or otherwise difficult solutions.

Wide Bore Pipette Tips

Available in LTS and Universal-Fit

Wide-orifice pipette tips are particularly useful for protecting the viability of cultured cells and maintaining the integrity of high molecular weight DNA. These tips are only supplied in racks and are available non-sterile and sterile.

Wide Orifice Pipette Tips

Reduce Sample Retention

Rainin wide-orifice LR low retention tips combine a wide aperture with a super-repellent fluoropolymer surface to aid in the dispensing of viscous/syrupy liquids, cultured cells and high-molecular polymers (such as genomic DNA). These tips reduce shear force and provide a super-slippery surface to reduce sample retention.
