    Area of Science:

    • Biotechnology
    • Laboratory Equipment Modification

    Background:

    • Precise liquid handling is crucial in biological assays.
    • Existing multidropper systems can sometimes deliver inconsistent volumes.

    Purpose of the Study:

    • To refine the Accu-Drop multidropper for single-drop delivery.
    • To develop a method for simultaneous inoculation of multiple petri dish compartments.

    Main Methods:

    • Teflon spaghetti tubing was fitted onto the Accu-Drop multidropper's needles to ensure single-drop dispensing.
    • A custom-drilled metal plate was fabricated to hold 25 inoculation cartridges.
    • The plate facilitated the simultaneous inoculation of 25 compartments within a divided petri dish.

    Main Results:

    Related Experiment Videos

  • The Teflon tubing modification successfully prevented the delivery of multiple drops.
  • The custom metal plate enabled efficient and simultaneous inoculation across 25 compartments.

    • Conclusions:

    • The modified Accu-Drop multidropper system offers improved precision for liquid handling.
    • This setup enhances throughput for experiments requiring simultaneous inoculation of multiple samples.
