  • pt and aptt fibrinogen assays

Tip Tops are cone-shaped, flexible polyethylene caps designed to fit 13 and 16 mm blood collection tubes, serum separating columns and other 13 and 16 mm vials. Filtered Tip Tops have a built-in membrane to remove fibrin clots and other particulates for trouble-free analysis with auto analyzers. A small opening at the top that allows you to dispense straight from the tube into sample cups. Specimens and reagents remain covered at all times, reducing the risk of accidental spills and exposure to infectious agents. One Tip Top can be used to dispense the same fluid again and again, eliminating the need for multiple transfer pipets.

Tip Tops are available only from Helena Plastics. Call toll free 800-227-1727. From outside the U.S. call 001-415-456-0100.
