The Clamping Cell
The elaborate measuring cells of SurPASS™ 3 suit any sample geometry, size or origin and give you the utmost flexibility for your quality control and investigations. The used measuring cell is recognized automatically.
The Clamping Cell is the tool of choice used with the SurPASS™ 3 for measuring planar surfaces like polymer films and sheets, metals, ceramics, glass or semiconductor wafers. A proprietary mechanism defines the contact pressure and thus guarantees highly reproducible sample mounting.
Flexible and outstanding
- For planar surfaces like polymer films and sheets, metals, ceramics, glass and semiconductor wafers.
- Two different sample arrangements are possible: in the symmetric configuration two identical surfaces are mounted and separated by a well-defined gap. The asymmetric geometry uses a reference surface.
- Enables the non-destructive measurement of samples with different thicknesses.
|Sample size||min. 35 mm x 15 mm|
|max. 40 mm|
Charge Formation on Polymer Surfaces
The zeta potential is one of the most sensitive indicators to monitor effects of activation and contamination of polymer surfaces.
From Inert to "Active" - Monitoring of Surface Treatment
The streaming potential method detects small changes in the surface properties of polymers and is thus a sensitive technique to tune surface modification processes.
Surface Modification of Kapton® Films
The zeta potential is a valuable parameter to follow polymer surface modifications and to tailor-make biocompatible devices for medical applications.
