An apparatus for measuring volumes of small objects

Area of Science:

• Biomedical Engineering
• Laboratory Equipment Design

Background:

• Accurate volume measurement of small biological samples is crucial for various scientific applications.
• Existing methods may be complex, expensive, or lack reproducibility.

Purpose of the Study:

• To describe a novel, inexpensive apparatus for measuring the volumes of small objects using fluid displacement.
• To demonstrate the reproducibility and ease of use of the developed apparatus.

Main Methods:

• The apparatus utilizes a micropipette, Erlenmeyer flask, Luer adaptor, and glass syringe for fluid displacement measurements.
• Volume is determined by the difference in fluid levels in the micropipette before and after object insertion.

Main Results:

• The apparatus provides reproducible measurements of small object volumes.
• The device is simple to construct and operate, offering a cost-effective solution.

Conclusions:

• This fluid displacement apparatus offers a reliable and economical method for determining the volumes of small objects.
• The design allows for calibration for absolute volume determination, enhancing its utility in research settings.
