Clear polypropylene tips feature a uniquely thin and flexible top that conforms to the pipettor barrel, forming a tight seal with minimal ejection force. The unbeveled point is extremely precise, allowing you to easily dispense the smallest sample. A beveled mounting port ensures easy mounting for multichannel pipettors. Tips are graduated at 10, 20, 50, 100, and 200µL. Lot-certified pure and free of human DNA, RNase, DNase, endotoxins, and heavy metals. Tips and hinged racks are autoclavable.
