SMTP4-500 μL is an air displacement pipetting module for sample aliquoting, with a nominal capacity of 500 μL. It can be integrated into sample preparation equipment and automated dispensing units for transfer to multiple vessels, diluent addition and reagent dispensing.
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:
Sample aliquoting, Diluent addition, Automatic tip ejection

SMTP4-500 μL is an air displacement pipetting module for sample aliquoting, with a nominal capacity of 500 μL. It can be integrated into sample preparation equipment and automated dispensing units for transfer to multiple vessels, diluent addition and reagent dispensing.
Transfer the sample into multiple vessels according to the target aliquot count and volume. The host can implement separate aspiration and dispense cycles; one aspiration followed by multiple dispenses requires checking the program, available travel, total delivery and method allowances. Verify first, intermediate and final aliquots separately.
Add diluent or buffer to the sample vessel according to the recipe, coordinating sample and diluent addition. The dilution ratio depends on delivered volumes; mixing is a separate instrument step. Recheck parameters after changing liquids or tips.
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.

500 μL is the nominal capacity; 0.25 μL/step is drive resolution, not a minimum reliable transfer volume or an accuracy specification. Working-volume selection must also account for usable tip capacity, method allowances and actual delivery performance with the intended liquid.
