PDF Catalog
  • Because this product applies heat on fine grain sample instantly and does not apply high temperature on dry fine powder sample itself, samples unstable to heat can be reliably changed into even fine powder.
  • Prepared fine powder will not be oxidized and contains minimum water and is contamination-free.
  • Drying is made directly from solution or suspension liquid sample into fine powder, which does not need pre- or post processes such as filtration, separation, or pulverization necessary in the conventional drying method and can be used without concern of contamination during a series of operations.
  • Model ADL311S-A is available to support organic solvent by connecting ADL311-A dedicated for water soluble samples and GAS410 solvent recovery unit to the standard model ADL.
  • Employment of a one-touch detachable mechanism in the drying chamber and the cyclone further improves ease of operation.
  • An arm jack is equipped as standard for useful installation and removal of attachments.
  • A service outlet (max.2A) and a sample stand are equipped as standard for connecting a magnetic mixer for stirring suspended liquid sample.
  • Employment of a unique peristaltic pump, nozzle cooling mechanism, pulse jet mechanism, and a nozzle knocker realize stable spray drying.
  • Global product lineup with multi-language multiple power supply and touch panels in Japanese, English, and Chinese.
