Drop Shape Analyzer – DSA100B

The system solution for contact angle measurement

The basic configuration of our Drop Shape Analyzer – DSA100 combines precision manual measurement of the contact angle with the technical advantages and robustness of the DSA100 system solution. The instrument enables reliable investigations of wetting to be carried out in quality assurance and research for pre-treatment and coating processes.

The sample height is adjusted exactly thanks to the fine drive on our manual lift table. The particularly delicate depositing or retrieval of the dispensed drop from the needle ensures gentle contact between sample and liquid. This prevents inaccurate measurement of the contact angle due to unintentional pre-wetting. Drops of a reproducible size for exactly reproducible conditions are generated by our manual dosing unit with the help of a micrometer screw.

The special features of the optical assembly include a particularly large sample chamber with rapid adjustment of the viewing angle as well as a high-resolution camera. Both options are also part of the basic version of the DSA100B.

Upgrades to all other system configurations are possible for the instrument and the software. You can therefore increase the degree of automation and standardization of the measuring sequence at any time. The comprehensive range of accessories for the DSA100 for adapting the measuring conditions to specific processes is also available.
