Clear, pretested, polypropylene resin 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, 200, and 300µL. Lot-certified pure and free of human DNA, DNase, RNase, endotoxins, and heavy metals. Tips and hinged racks are autoclavable.
Ordering Information: Pak Rak® Express refills contain pipet tips to fill 8x12 racks, without the packaging waste of standard tip boxes. Pak Rak Express refills require the Pak Rak system loader (see 30128-374 series), which dispenses tips quickly and easily from the refill pack into each rack, eliminating risk of contamination from hands or gloves.
