Serial Dilution

𝐒𝐄𝐑𝐈𝐀𝐋 𝐃𝐈𝐋𝐔𝐓𝐈𝐎𝐍

✓ Serial dilution is a simple yet essential laboratory technique used to gradually reduce the concentration of a sample through a series of stepwise dilutions, often following a fixed ratio like 1:10.

✓ By transferring a measured volume of a concentrated solution into a diluent and repeating the process, serial dilution helps achieve manageable concentrations for accurate analysis.

✓ It is widely used in microbiology, pharmaceuticals, and environmental testing to count microorganisms, assess contamination, and evaluate product safety.

✓ Proper technique, sterile conditions, and precise measurements are key to ensuring reliable results.
