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.
