SMTP4-100 μL is an air displacement pipetting pump for small-volume sample transfer, with a nominal capacity of 100 μL. It can serve as a pipetting component in sample preparation equipment and automated analyzers, transferring samples from tubes into reaction tubes, sample cups or microplates.
The product uses disposable tips and supports automatic tip ejection. The integrator supplies drive electronics, positioning axes and process control. Specify a separate sensing arrangement if liquid-level, blockage or tip-status monitoring is required.
Typical Applications:
Small-volume sample transfer, Sample preparation, Disposable tips

SMTP4-100 μL is an air displacement pipetting pump for small-volume sample transfer, with a nominal capacity of 100 μL. It can serve as a pipetting component in sample preparation equipment and automated analyzers, transferring samples from tubes into reaction tubes, sample cups or microplates.
Aspirate the target volume from a sample tube and use the positioning axes to transfer it to a reaction tube, sample cup or well. Coordinate immersion depth, aspiration and dispense speeds, delays and dispense position. Evaluate the volume actually delivered to the destination vessel.
Use the vessel opening, bottom geometry and tip length to define dispense height and withdrawal for tubes, sample cups and microplates. Check residual liquid and liquid carried on the tip exterior, and assess contact dispensing with the intended liquid.
Match tip loading, pipetting and ejection paths to the tip part number, rack position and vessel layout. Automatic tip ejection still requires coordinated instrument motion. Confirm sealing, loading and ejection forces, and mechanical travel for the selected tips.
Provide minimum, routine and maximum working volumes, liquids, tip part numbers, vessels and target cycle time, then define drive and sensing arrangements. Select against the model's resolution and usable capacity and validate accuracy and repeatability under actual conditions. Drive resolution is not a minimum reliable transfer volume or an accuracy specification.

100 μL is the nominal capacity of this configuration; 0.05 μL/step is its drive resolution. A drive increment is not a minimum reliable pipetting volume or a volume-error specification. Verify performance at minimum, routine and maximum working volumes with the intended tips, liquids and aspiration/dispense method.
