A specialized glass container (often a Dean-Stark trap) that allows for the measurement of the volume of water collected. Heater: Provides controlled heat to maintain a steady boil.
Read the volume of the accumulated water layer at the bottom of the graduated trap directly from the meniscus. 📊 Calculating the Results
ASTM D95, officially known as "Standard Test Method for Water and Sediment in Crude Oil by Centrifuge," is a widely used standard that outlines the procedure for quantifying the water and sediment content in crude oil using a centrifuge. The presence of water and sediment in crude oil can lead to various issues, including corrosion in transportation and storage facilities, catalyst poisoning in refineries, and difficulties in the overall processing and handling of the oil.

Typically a glass round-bottom or short-neck flask ranging from 500 mL to 1000 mL in capacity, or a metal still for bituminous materials.
ASTM D95 is a standardized test method developed by ASTM International. It measures the volume of water in petroleum products, tars, and other bituminous materials within the range of . The Core Principle: Dean-Stark Distillation
Since water and the solvent don't mix and have different densities, the water settles at the bottom of the trap. The solvent overflows back into the flask to continue the process. Measurement:
