DS1120

Our specially developed Micro Dispensers equips your tensiometer for measuring the critical micelle concentration (CMC) with the utmost precision, using one or two Dispenser units (DS110 or DS1120). The surfactant concentration range is set up and measured fully automatically.

Working with two Micro Dispensers, where one dispenses the liquid and the other extracts the same volume, has great advantages. This enables a very wide concentration range with a high density of measuring points to be created in order to measure the CMC with high accuracy. Wrong measurements due to a too highly concentrated parent solution are virtually ruled out, as it can be diluted by several orders of magnitude and the CMC measured with high probability.
