With the multi-channel pipettes you have the option of either a 5 µL - 50 µL or 30 µL - 300 µL in both the 8 and 12-channels. With the unique, long tip ejector lever and movable lower body can be rotated a full 360° relative to the handle to provide maximum comfort for left- or right-handed use. The isolated volume adjustment makes it so there's no need for a locking mechanism to prevent accidental volume adjustment. Our new generation of pipettes has a dual indicator that improves the volume adjustment accuracy by removing the parallax errors. SoftGrip pipettes have a universal calibration key that reduces the need for costly calibration services. Calibration requires only minutes to perform and eliminates the downtime and cost of alternative calibration methods. The SoftGrip tip nozzle ensures a proper fit with universal pipette tips. Unique color coding and labeling clearly indicates the working ranges of the adjustable volume pipettes.
