Saline is commonly used for swabs in microbiology and clinical applications because it
provides an isotonic environment that preserves cell integrity

Saline keeps the swab moist, preventing the sample from drying out, which helps in
recovering microorganisms or cells during testing.

It doesn’t kill or alter the microorganisms, ensuring an accurate sample for culturing or
analysis.

Being isotonic (same salt concentration as cells or tissues), saline prevents osmotic stress that
could damage the microorganisms or cells being collected.
