With a capacity of 22 g and a readability of 1 µg, the XP26PC fulfills ISO 8655 requirements for micropipettes down to a volume of 1 µl. Operating efficiency is guaranteed by the light barrier which allows hands-free opening of the trap door. The built-in evaporation trap avoids errors caused by evaporation of the test liquid during weighing. System speed and throughput is further increased by the presence of a large waste container allowing for continuous pipetting without interruptions.
