Fully Automatic Ultrasonic Cleaning

• SCHOTT glass is cleaned by an automated
  ultrasonic cleaning line in a series of wash
  steps using commercial cleaning solutions
  recommended for optical glass
• Highly alkaline cleaner (pH 12.4) containing
  alkalis, surface active compounds, solubiliser,
  wetting agents, complexing agent, sequestering
  agents
• Mildly acidic (pH 4.3) containing acids, wetting
  agents, surfactant compounds, buffer compounds
• Rinse steps in deionised water
• Final infra-red drying stage
