AHN universal fit tips are engineered for a wide variety of pipettors and are ideal for laboratories with multiple brands of pipettors – even multi-channel pipettors. Our universal tips feature the universal grip design, using flexible materials with a series of bands and supports producing a positive seal. AHN tips have thin walls and a small surface area at the tip, greatly minimizing the possibility of the tip retaining sample droplets. In addition the small surface area reduces the touch-off angle between the outer tip wall and the receiving sample tube. This reduced touch-off angle virtually eliminates the potential of capillary retention between the tip orifice and tube wall. Each of our tips is molded to give a flash-free and uniform delivery orifice for consistent accuracy and reproducible sample delivery.All our tips are provided with calibration lines at specific volumes, acting as visual checks to minimize any risk of errors during sample aspiration.
