Tips are graduated at 2 and 10µL. RNase- and DNase-free. Sterile tips are endotoxin-free. Tips and hinged boxes are fully autoclavable to 122°C (252°F).
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.
