The LONG GripTip pipette tip is designed to work with single, 8-, 12-, and 16-channel Viaflo electronic pipettes and Voyager 8- and 12-channel adjustable-spacing electronic pipettes. The extended-length design enables access into labware types such as 1.5 mL tubes and deep-well blocks. The design also reduces PCR cross contamination, as the elongated tip prevents the pipette shaft from touching the wall of the PCR tubes.
