Measurement of Fabricated Membrane Diameter Using Vernier Caliper | Pre & Post Fabrication Analysis

In this tutorial, I demonstrate the measurement of the diameter of a fabricated membrane using a Vernier caliper, which is a critical step in membrane fabrication and characterization.
The video focuses on:
Measuring the membrane diameter before fabrication (selected/target diameter)
Measuring the post-fabricated membrane diameter
Comparing pre- and post-fabrication values to verify whether the fabricated membrane matches the selected mold or thickness
Proper handling and use of a Vernier caliper for precise dimensional analysis
Importance of diameter consistency in membrane performance, module fitting, and experimental reproducibility
This step is essential to confirm that the fabrication process does not cause significant dimensional shrinkage or expansion, which may affect:
Effective membrane area
Permeability calculations
Flux and rejection studies
Reproducibility of experimental results
This tutorial is highly useful for:
Environmental Engineering students
Membrane science and polymer research beginners
Laboratory practical classes
Researchers working on fabricated flat-sheet or circular membranes
📌 Applicable for academic labs, research projects, and membrane characterization studies.
