SP13 Air Displacement Pipetting Module — 9 mm Tip-to-Tip, 0.5–1000 µL

Dispense samples, controls and reagents in chemiluminescence immunoassay workflows.

Support qPCR or NGS sample-preparation steps such as reagent addition, mixing and transfer.

Align up to eight standard units at 9 mm pitch for row-based plate transfer.

Develop dilution, normalization, aliquoting and quantitative dispensing methods.

Integrate one channel or a compact multi-channel head into a tailored motion architecture.

Use drawings and protocol files to prototype and validate new workflows.

Combine 9 mm layouts, dual LLD, aspiration monitoring and automatic tip handling in one module platform.

Address low-volume additions and transfers up to 1 mL, with published reference data at defined test points.

Use 24 VDC and CAN, with RS485 available in the supported configuration and Keyto HSZ compatibility.

The published barrel-life specification is greater than one million cycles; final service life depends on use conditions.

Multi-Channel Plate Layouts

Nine-millimeter center spacing matches a standard 96-well plate. Up to eight standard SP13 units can align with one row and operate independently or in groups.

Integration value: direct plate-pitch alignment can reduce added lateral positioning in the pipetting head.

Dual Liquid-Level Detection

pLLD detects pressure change without relying on conductivity; cLLD detects capacitance change for conductive liquids. The fastest specified response is 3–5 ms.

Integration value: select a detection method for conductive or non-conductive liquid classes.

Aspiration Monitoring

SP13 provides signals for tip presence, clots, foam or bubbles, and aspiration of air. The host instrument determines the validated response.

System value: expose abnormal-transfer signals to host logic for defined recovery or result handling.

Automatic Tip Pickup and Ejection

A compatible Z-axis positions the SP13 for tip pickup, deck movement and ejection. Tip-presence monitoring helps confirm pickup before aspiration.

Workflow value: disposable-tip automation supports carryover-control strategies and unattended workflows.

How Air Displacement Pipetting Works

The motor-driven plunger changes the volume of a sealed air column. Retracting it aspirates liquid into the disposable tip; advancing it dispenses the programmed volume. The liquid remains in the replaceable tip rather than entering the pipetting barrel.

Liquid properties, tip sealing, calibration, speed and pre-wetting should be validated for each liquid class.

SP13 manual Table 2-2 reports 5% accuracy and 2% CV at 5 µL with a 50F tip, and 1% accuracy and 0.75% CV at 1000 µL with a 1000F tip. Review the complete table and test conditions in the Specifications tab.

Evidence note: these are published reference points under defined water test conditions, not a guarantee of final-instrument performance.

Quality system: The SP13 is manufactured under an ISO 13485 quality management system.

Use the published configuration options as a starting point, then confirm model, drawing, motion, communications, tips and liquid classes before design freeze.

Requirements outside the published options should be discussed with Keyto before they are included in the instrument specification.

CAN control; RS485 is available in the supported configuration.

24 VDC standard supply requirement.

Compatible with Keyto HSZ for automatic tip handling and liquid-level following.

Up to eight standard units at 9 mm pitch with independent or grouped operation.

Specified tip-volume options: 10, 50, 200 and 1000 µL.

Confirm Model A or Model B against the current drawing and mechanism requirements.
