Moisture Determination Apparatus Dean and Stark

Moisture Determination Apparatus Dean and Stark, made from borosilicate glass by Glass Agencies, is a specialized laboratory setup used for accurate determination of water content in various substances through distillation. This apparatus is widely used in chemical laboratories, petroleum testing units, food processing industries, pharmaceutical laboratories, and research institutions where precise moisture analysis is required. Manufactured using high-quality borosilicate glass, it offers excellent resistance to heat, chemicals, and thermal shock, making it suitable for continuous operation involving organic solvents and elevated temperatures. The apparatus typically consists of a distillation flask, condenser, and a calibrated receiver, all designed to work together efficiently for moisture separation. During operation, the sample is heated with a suitable solvent, and the water content is distilled along with the solvent vapor. The vapor then condenses and collects in the receiver, where water separates from the solvent due to density differences, allowing direct measurement of moisture content. The transparent glass construction allows clear observation of the entire process, enabling users to monitor boiling, condensation, and collection stages effectively. The receiver is accurately calibrated to ensure precise measurement of collected water, supporting reliable analytical results. The joints are carefully finished to provide secure and leak-resistant connections, ensuring safe operation and preventing vapor loss. The smooth inner surfaces reduce residue buildup and make cleaning simple, which is important for maintaining accuracy and avoiding contamination between tests. This apparatus is suitable for moisture determination in a wide range of materials including oils, fuels, food products, and chemical compounds. Glass Agencies follows strict quality control standards during manufacturing to ensure each unit meets industry expectations for performance, durability, and consistency. The ergonomic design allows easy assembly, handling, and maintenance, making it convenient for routine laboratory use. With strong construction, chemical resistance, and clear visibility, this moisture determination apparatus provides dependable performance and accurate results. It serves as an essential tool for laboratories requiring precise moisture analysis, supporting efficient workflows and consistent outcomes in various scientific and industrial applications.
