Moisture Determination Apparatus, Dean and Stark with Screw type PTFE Key Rotaflow Stopcock, Borosilicate Glass

Moisture Determination Apparatus, Dean and Stark with Screw Type PTFE Key Rotaflow Stopcock, made from borosilicate glass by Glass Agencies, is a specialized laboratory setup developed for accurate determination of moisture content in various substances through distillation. This apparatus is widely used in chemical laboratories, petroleum testing units, food processing industries, pharmaceutical facilities, 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 operations involving organic solvents and elevated temperatures over extended periods. The apparatus typically includes a distillation flask, condenser, and a calibrated receiver, all designed to function together efficiently for moisture separation and measurement. During operation, the sample is heated with a suitable solvent, allowing the water content to vaporize along with the solvent. The vapors condense and collect in the receiver, where water separates due to density differences, enabling direct and accurate measurement. The transparent glass body allows clear observation of the entire process, including boiling, condensation, and liquid collection, helping users monitor performance effectively. The receiver is precisely graduated to support accurate readings of moisture content. The screw type PTFE key Rotaflow stopcock provides smooth, controlled discharge of the collected liquid while ensuring a tight, leak-resistant seal. Its chemical resistance and ease of operation enhance safety and reliability during use. The ground joints are carefully finished to ensure secure connections, minimizing vapor loss and maintaining consistent results. The smooth inner surfaces reduce residue buildup, allowing easy cleaning and preventing cross-contamination between samples. This apparatus is suitable for moisture determination in oils, fuels, food products, and various chemical materials. Glass Agencies follows strict quality control measures to ensure each unit meets industry standards for accuracy, durability, and performance. The ergonomic design allows easy assembly, handling, and maintenance, supporting efficient laboratory workflows. With strong construction, clear visibility, and a reliable PTFE Rotaflow stopcock, this apparatus provides dependable performance and precise results, making it an important tool for laboratories focused on accurate moisture analysis.
