New generation of fully autoclavable manual pipettes from DLAB: Ergonomic design reduces fatigue and provides a smoother and easier pipetting experience. With a one-stop point of 4N and two-stop points of 10N, the DLAB pipette offers a comfortable single-handed pipetting experience with smooth and effortless operation. Offers nine different single-channel adjustable volume models, ranging from 0.1 µl to 10 ml, making it ideal for various laboratory applications. Hipette features a new piston and metal screw structure, ensuring precise suction and dispensing of liquids. Its counter increment is one thousandth of the volume range, making it easy to set and read. Hipette has a one-click volume lock feature that helps prevent pipetting errors caused by accidental volume changes, allowing for more accurate transfer of small volumes of liquids. Hipette offers a smooth and easy volume adjustment experience, ensuring high precision and accuracy. High-Quality Materials: The DLAB pipette is made of a new type of material that does not require disassembly for autoclaving or UV disinfection, and is resistant to harsh chemicals. Hipette is equipped with an individual filter system that reduces volatile reagents from entering the pipette and causing over-aspiration or corrosion of the piston. Easy Maintenance: The DLAB pipette is easy to disassemble and comes with tools that can be used to calibrate and maintain the pipette in the laboratory. Hipette has ISO9001:2015 and ISO 13485:2016 certifications, as well as CE marking, ensuring its quality and reliability. Hipette can be calibrated online via the official website, ensuring its accuracy and reliability.
