Automatic pipette SP28

air displacementpiston1-channel

The SP28 is a programmable, automatic air displacement pipette pump independently developed by Keyto for use with disposable tips to achieve precise dosing aspiration and dispense. This pipette allows for automatic tip pick-up and ejection, tip presence detection and liquid level detection, etc. The SP28 pipette pump also offers extremely high dispense precision and accuracy, with a service life of over 1 million cycles without compromising precision and accuracy. Long life and high-performance 1.8° hybrid two-phase step motor with long-life and high-performance. Extremely high and stable dosing aspiration and dispense accuracy Extremely high and stable dosing aspiration and dispense accuracy over the life cycle of the pipette pump. Life expectancy Unique piston machining technology, rigorous inspection procedures and reliable sealing solutions guarantee a life expectancy of more than one million cycles without maintenance. Good chemical resistance Good chemical resistance of the pipette pump components: (1) Pump head material: aluminium alloy; (2) Piston material: stainless steel. End position optical detection End position optical detection. The optical sensor detects whether the pump is at the initial position of aspiration. Tip presence detection and tip ejection Automatic tip presence detection and tip ejection. Detection Automatic pneumatic liquid level detection and tip clogged detection.
