SURFTENS universal

SURFTENS universal basic version with 1 manual dosing unit

 

The modification of the wetting ability of technical surfaces by special surface treatments becomes more and more common in industry and research. For process characterization, adjustment of technological parameters and production control it is therefore absolutely necessary, to measure the surface free energy objectively and accurately before and after the modification process.

Dosing unit features

-optional equipment with manual or motorized dosing systems

-1-3 dosing systems per device

-manual and motorized dosing systems can be combined

-repeatability of the drop volume: 0.1 µl

-smallest drop volume: 0.2 µl

-optional motorized drop placement for both types of dosing systems

 

 

Other features

-Zoom optics

-Lift table, laterally extractable (for easy sample placement)

SURFTENS universal with motorized dosing unit

-Sampling table can be moved laterally to place drops next to each other

-bright, homogeneous long life LED back-lighting

-Camera 1.3 MPixel

-adjustable viewing angle (optional)

-Manual z-axis for exact height adjustment of the dosing system

-Measuring table with 100 mm diameter, 40mm height drive

-Fine drive to focus the zoom optics

-Fine drive for transverse displacement of the zoom optics (for centering the needle in the image field)

-Software for measuring the contact angle and the FSE of solid bodies (corresponds to DIN 55660-2: 2009-07)

-Optional equipment with manual or motorized cross table

-fully automatic measurement of the contact angle with highest accuracy.

-software includes a module for calculation of surface free energy (SFE) using the contact angles of up to 5 test liquids
