Dean And Stark Apparatus

About Dean And Stark Apparatus

The Dean and Stark Apparatus is a specialized laboratory glassware setup used for the determination of water content in various substances through azeotropic distillation. It is widely employed in chemical, petroleum, and food industries for accurate moisture analysis, particularly in oils, bitumen, and organic compounds.

The apparatus works by separating water from a sample using an immiscible solvent, typically through reflux distillation. The collected water is then measured in a calibrated receiver, providing precise and reliable results.

Key Features:

• Accurate moisture determination by azeotropic distillation
• Made from high-quality borosilicate glass for durability and thermal resistance
• Clear and precise calibration markings
• Resistant to chemicals and high temperatures
• Easy assembly and operation
• Available in different capacities and configurations

Applications:

• Petroleum and oil testing laboratories
• Chemical and pharmaceutical industries
• Food processing and quality control
• Research and educational laboratories
• Bitumen and asphalt testing

Technical Specifications (Typical):

• Material: Borosilicate Glass
• Capacity: 5 ml, 10 ml, 25 ml receiver (customizable)
• Joint Size: Standard ground glass joints
• Method: Azeotropic distillation
• Compatibility: Suitable for organic solvents like toluene or xylene

Packaging Details:
Carefully packed in protective materials to prevent breakage during transit.

Usage Instructions:

1. Assemble the apparatus with flask, condenser, and receiver.
2. Add sample and solvent into the distillation flask.
3. Heat the mixture to initiate distillation.
4. Collect and measure separated water in the calibrated receiver.

Safety & Maintenance:

• Handle glassware carefully to avoid breakage
• Use in a well-ventilated area
• Clean thoroughly after each use
• Avoid sudden temperature changes to prevent cracking
