Coaxial Capillary System
CCS-1M
Controlled liquid exchange at the liquid interface.
The CCS-1M extends the PAT-1M with a coaxial capillary system for controlled liquid exchange during pendant drop and buoyant bubble experiments. It enables dynamic surface and interfacial tension measurements while the surrounding liquid phase is continuously replaced.

The CCS-1M module
Controlled liquid exchange without disturbing the interface.
The CCS-1M is based on a coaxial capillary system with two independently controlled syringes. A pendant drop is first formed through the external capillary. During the experiment, the subphase can then be exchanged through the internal capillary while the PAT-1M continuously measures the dynamic surface or interfacial tension.
This unique approach enables in-situ liquid exchange without destroying the existing interface. Researchers can investigate adsorption, competitive displacement and interfacial dynamics under precisely controlled experimental conditions.

Measurement principle
Exchanging liquids while preserving the interface.
The CCS-1M is based on a coaxial capillary system consisting of an external and an internal capillary connected to two independently controlled syringes. A pendant drop is first generated through the external capillary. During the experiment, the internal capillary introduces a new liquid while the external capillary simultaneously withdraws the original subphase, allowing continuous measurements without disrupting the interface.
