The Signature™ Single-Channel Adjustable Pipette, 5-50 µL, VWR International is designed with an extended curved finger stand to allow the pipette to maintain balance on the index finger, and the plunger and volume adjustment force are significantly reduced to eliminate the pressure of repeated pipette. In order to adapt to a variety of tips, the easy grip push out system provides adjustment of the push out height. The stainless steel structure of the ejector prevents corrosion and bending. These lightweight, durable pipettes are fully autoclaved and offer laboratory calibration tools and a three-year warranty. Use the micrometer wheel or distributor button to adjust the volume setting continuously. The locking mechanism prevents unexpected volume changes when using the instrument.
