Titertek® premium-quality pipette tips allow your pipette to work the way it was designed— at peak performance and with the best possible accuracy and precision. To achieve this level of consistency, Titertek® tips are manufactured from only the best quality raw materials, and are precision-molded using state of the art equipment. Attention to detail and quality control results in perfect fit, perfectly formed flash-free orifices, and non-wettability in the final product. Mold release agents are not used, and special care is taken to ensure the manufacturing environment is kept as clean as possible. Titertek® tips have a very low coefficient of friction and are hydrophobic (non-wettable) in nature. Titertek® pipette tips are manufactured of virgin, non-wettable polypropylene material to reduce fluid retention and optimize instrument performance. Robot-compatible (large-Micron) hydrophobic filters effectively eliminate instrument contamination caused by aerosol formulation during pipetting procedures. All presterilized Titertek® filter tips are certified RNase-free, DNase-free, pyrogen-free, and trace metal-free. Titertek® tips give superior results, optimal yield, and minimal sample loss compared to inferior pipette tips.
