Detailed information

Handling & Precautions

  • Ensure the funnel is properly seated on a filter flask using a suitable rubber adapter.
  • Do not subject the funnel to sudden temperature changes—allow gradual heating or cooling.
  • Clean immediately after use with mild detergents; avoid abrasive tools.
  • Suitable for autoclaving; ensure slow depressurisation to prevent stress.
  • Avoid using hydrofluoric acid or strong alkaline solutions at high temperatures, as these may damage the glass.
  • Inspect regularly for cracks or chips before vacuum use.
