Little things makes big differences. The angel on AHN Biotechnologie filter tips reduces the surface of the tip orifice with the receiving vessel. This angel combined with an ultra-thin orifice reduces the effect of liquid samples creeping up the side of the tip (capillary effect). By reducing this capillary effect, Top-Lin® tips and filter tips dispense more accurate volumes. This new innovating universal tip fits all popular pipettors and fits through the innovative design also in small reaction vessels. Choose AHN Top-Line® tips version for easier drop touch off. Graduated AHN tips provide calibration lines which acts as a visual check to minimise any risk of errors during sample aspiration. AHN filter tips are sterilized by radiation (Gamma or Beta irradiated) and available in an innovative hinged rack-system or in bags as sterile or non-sterile versions. All filter tips are naturally certified RNase, DNase and pyrogen free and fully autoclavable (121° C/15 min). Quality and precision Made in Germany.
