Short Path Evaporator<\/h1><\/div>

Short-path evaporation is an advanced technology designed for the efficient separation of high-boiling, temperature-sensitive organic compounds. Operating under ultra-fine vacuum conditions (up to 1\u00d710\u207b\u00b3 mbar), its innovative design minimizes heat load through reduced distances between the evaporator tube and integrated condenser. The system\u2019s high-quality glass construction ensures exceptional process visibility, allowing precise adjustments to feed rates for optimal control and reliability.<\/p>\n<\/div>

    The short path evaporator is specifically designed for sensitive substances such as active pharmaceutical ingredients, essential oils, and specialty chemical products. Its precise method ensures gentle processing, starting with the controlled supply of the feed mixture into the evaporator tube. An optional pre-degasser can be used to remove unwanted gases or low boilers, enhancing preparation.<\/p>\n

    Inside the evaporator, a rotating wiper system spreads the liquid as a continuously renewed thin film, maximizing heat transfer and evaporation efficiency. The short dwell time of molecules in the hot gas phase minimizes thermal stress, safeguarding the integrity of heat-sensitive substances throughout the process.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

    Reliable Solutions for High-Purity Separation<\/h4>\n

    Short path evaporators are expertly designed for precise separation, efficiently condensing highly volatile components (low boilers) into distillates while isolating heavier residues. The minimal distance between the evaporator and condenser ensures optimized separation, making these systems ideal for demanding processes in pharmaceutical production, cosmetics formulation, and fine chemical applications.<\/p>\n<\/div><\/div><\/div>
