The PIPETMAN® M line of single and multichannel electronic pipettes now includes a programmable custom mode and performance specifications for the repetitive pipetting mode within ISO 8655-2 recommendations. This ensures reliable performance from the first to the last aliquot, when performing repetitive pipetting. An intuitive interface, with just two buttons, allows users to easily reach the five available modes: pipet (standard), repetitive, mix, reverse, and custom (personalized) mode. With the new personalized pipetting mode, researchers create their own multistep pipetting protocols, which are executed automatically so there is no need for repetitive button pushing that can cause stress injuries. The product line includes eight single-channel (from 0.5 μL to 10 mL) and 12 multichannel (from 0.5 μL to 1200 μL) options for precise volume selection.
