Axygen MultiRack Tips are supplied in convenient hinged racks that help reduce airborne contamination of the tips during use. Each rack is individually sealed. The high-quality polypropylene racks are reusable and fully autoclavable. They can be refilled with Axygen MultiRack Reload Systems to save both money and plastic. Sturdy racks resist accidental tipping, and the easy-close lid lock prevents tips falling while closed. The transparent rack and color-coded decks allow easy size identification.
