The Diamond APEX 8-channel and 12-channel pipettors include the myriad of features found in the single channel models and more. Simple operation and light weight aid in reducing fatigue and a 360° rotating manifold allows for positioning vertically or horizontally while aspirating or dispensing. As with the single channel models, every multi-channel Diamond APEX pipettor is calibrated in an ISO17025 accredited facility and come standard with a 3-year warranty.
