Air bubbles, found in the measurement chamber during the measurement, kcan lead to inaccurate readings.
Hellma Analytics has therefore constructed the flow-through cells so that air bubbles cannot influence the measurement:

• A space (dome) has been created above the actual measurement chamber into which the bubbles can rise.
  
  
• Flow-through cells are subjected to a special treatment which reduces bubbles sticking to the glass surface in the chamber.
  
  
• Hellma Analytics flow-through cells display the lowest cross-diameter variation to effectively prevent bubbles occurring.
