The DSA100: Why we call it premium

Comprehensive and versatile wetting and adhesion analysis for almost all surfaces and tasks: see what’s possible with the DSA100.

Manual precision dosing for quick changes of liquids

Thanks to the fine adjustment of the manual dosing unit of the DSA100B, the drop is dispensed in an accurately controlled manner. The size of the drop is therefore highly reproducible and provides a good comparison of results. The quickly replaceable syringe allows a rapid changeover between different liquids, thus enabling a high sample throughput.

 

 

Reliable drop shape analysis thanks to high imaging quality

The DSA100B features a high-resolution camera and a quality zoom lens for accurate display of the drop with optimum size. Combined with the intelligent image evaluation algorithm of the ADVANCE software, drop shape analysis with the instrument provides exact results.

 

 

Protective housing and time-saving setup

The robust housing of the DSA100B protects sensitive components such as the camera and also minimizes the troublesome effect of vibration.

 

Adjusting the viewing angle, which is often necessary when measuring the contact angle, is particularly easy since the position of the drop in the image does not change during this step. As a result, the otherwise necessary tracking of the sample height is eliminated. This is possible thanks to a special optical arrangement, which also creates space for large samples.

 

 

Many accessories and upgrade options

In addition to extensive accessories, e.g. for temperature control, we provide extensive upgrade options for the DSA100B to the Standard (S) and Expert (E) unit configurations. These offer you software-controlled drop dosing of up to eight liquids as well as manual or even automated horizontal and vertical sample positioning.
