Foam behavior with gases such as nitrogen or CO2 can differ considerably from foam formation and stability with air. You can equip your DFA100 with a PA4530 external gas connection in order to simulate technical processes involving these gases. This also expands the flow rate range of your instrument so you can foam with air in very small rates of down to 0.05 L/min.
Your instrument can be converted quickly and simply to allow it to introduce the connected gas through the sample by means of accurate electronic flow control. In this way you can create exactly repeatable foaming conditions.
