Moisture Determination Apparatus

What is it?

The Moisture Determination Apparatus, commonly known as the Dean-Stark Apparatus, is a specialized laboratory assembly used to measure the water content in various materials like oils, petroleum products, and food samples. It works by heating the sample with an immiscible solvent; the water is distilled out, collected in a graduated trap, and measured precisely to determine the moisture percentage.

Complete Set Includes:

• Round Bottom Flask: Heavy-duty boiling flask for even heating of the sample.
• Dean-Stark Receiver/Trap: A graduated glass tube (with or without stopcock) for accurate volume measurement of the collected water.
• Liebig Condenser: High-efficiency cooling tube to ensure all vapors are condensed and returned to the trap.

Key Features and Benefits

• Premium Borosilicate 3.3 Glass: Manufactured from superior heat-resistant glass that handles continuous boiling and rapid temperature changes safely.
• Precision-Ground Joints: Features standard interchangeable ground glass joints for a perfectly airtight and leak-proof assembly.
• Clear, Durable Graduations: The receiver features permanent white or amber enamel markings for easy and accurate reading of moisture levels.
• Chemical Resistance: Highly resistant to a wide range of solvents and corrosive chemicals, ensuring no contamination of your samples.
• Uniform Wall Thickness: Built with balanced glass thickness to provide maximum mechanical strength during heating cycles.

Available Receiver Capacities

We manufacture receivers in several standard sizes to suit your testing requirements: 2mL, 5mL, 10mL, 12.5mL, and 25mL.

Quality Commitment: Every Moisture Determination set is meticulously hand-finished and annealed to remove internal stress, ensuring safe and reliable performance under high-temperature distillation conditions.
