Wet Digester System B-440
It automatically removes and neutralizes the acid fumes, preventing contamination of lab and outdoor air by these corrosive fumes. In addition, laboratory fume exhaust and ventilation systems are protected from corrosion.
  1. Features
  2. Specification
  • Applications: The wide temperature range (100 - 550 °C) allows for many uses:
    • ash determination
    • sulfate ash determination
    • wet incineration
    • evaporation of volatile acids and bases
    • heating of samples (e.g. for reactions) etc.
  • In addition to neutralizing the emissions the Wet Digestion System improves efficiency and safety. All acid fumes are removed and neutralized. The BUCHI system is made up of two main components, i.e. the Wet Digester B-440 and the Scrubber B-414:
    • The samples are placed in the Wet Digester for preincineration. Since each set of samples can be different, the heat source (a halogen lamp) can be programmed to produce an optimum temperature versus time profile for each set of samples and stored for recall at a later time. Once the program starts, the acid fumes produced are removed and neutralized by the scrubber.
    • Subsequently the neutralized fumes are emitted without polluting the environment. Therefore, the consequences of contamination, corrosion and pollution are eliminated with the B-440/414 System. By this means the emissions are reliably under control - an investment which soon pays for itself, reliable and ecologically safe.
