Rainin - Wide-orifice Tips

Wide-orifice Tips for Universal-fit Pipettes. Rainin’s Wide-orifice tips for universal-fit pipettes are ideal for the manipulation of delicate samples, such as cultured mammalian cells or high molecular-weight DNA. The 1.5 mm wide orifice minimizes shear force and offers less resistance when pipetting viscous or particulate samples. They are available both non-sterile and sterile.
