Excellent recovery rates even with difficult sample matrices in water and soil analysis: Simultaneous heating and stirring with the compact distillation apparatuses with magnetic stirrer for cyanide determination. With integral magnetic stirrer, suspended absorption vessel, and dropping funnel for reagent additions, the installation corresponds with the draft document for the new DIN/EN/ISO methods. The special behr absorption container with exact behr bore guarantees the full absorption of cyanide and full rinsing into the measurement flask.
