SADP28 Air Displacement Pipettes

SADP28 Air Displacement Pipette

The SADP28 series pipette integrates a controller with RS232, RS485, and CAN communication for convenient control. Driven by a stepper motor, it supports precise aspiration and dispensing, automatic tip ejection, and offers dispensed volume from 5μL to 1000μL. With optical detection for tip presence and integrated automatic pressure-based liquid level and clot detection, it ensures reliable performance. Its chemically resistant nozzle components and durable design ensure a lifetime exceeding 1 million cycles without maintenance.
