Reasons to Buy Keyto Air Displacement Pipette SP18

  • 01
    Unique mechanical structure

    This pipette has a unique mechanical structure that allows multiple air displacement pipettes to be used in conjunction with each other, and the loading of disposable tips allows 18 mm tip-to-tip center spacing, which greatly increases pipetting velocity.

  • 02
    With a excellent-performance drive control unit

    The pipette is equipped with a excellent-performance drive control unit and provides CAN, RS232 and RS485 communication interface and the corresponding protocol, allowing the SADP to be easily and quickly applied by the host computer.

  • 03
    With powerful sensors and algorithms

    The pipette is equipped with powerful sensors and algorithms, which can be applied to all kinds of reagents as well as high-speed liquid level detection in high humidity environment, shielding the interference of liquid film, while supporting the function of sample clot detection.

  • 04
    Allows for automatic tip pick-ups and ejection

    This pipette allows for automatic tip pick-ups and ejection, as well as tip drop detection.

  • 05
    Without maintenance

    Advanced cylinder machining technology, strict inspection procedures, and unique sealing solutions, which ensure that the cylinder's service life can reach more than 1 million cycles without maintenance.

  • 06
    Lightweight and convenient

    This pipette is designed to be lightweight and convenient, weighing no more than 400g per pipette.
