Air Displacement Pipetting Modules for Automated Liquid Handling

FOREACH air displacement pipetting modules use disposable tips for liquid aspiration and dispensing in automated analyzers, sample preparation equipment and laboratory workstations. These pipetting pumps support sample transfer, reagent addition and aliquoting. The range includes SMTP2 and SMTP4, with nominal capacities of 100 μL, 250 μL, 500 μL and 1000 μL.

Select a pipetting module by minimum, routine and maximum working volumes, together with accuracy, repeatability and cycle-time requirements. Consider liquid properties, tip compatibility, installation space and the instrument's control architecture. Nominal capacity and drive resolution are separate specifications; actual pipetting performance must be verified with the intended liquid, tips and aspiration and dispensing parameters.

SMTP2 integrates drive and control with liquid-level, blockage and tip detection for automated stations that require pipetting-status feedback. SMTP4 provides air displacement pipetting and automatic tip ejection, with drive and process control supplied by the instrument. Compare the series by monitoring requirements and control architecture, then select a nominal capacity for the working volumes and confirm tip compatibility and mounting arrangements.
