The Drop Shape Analyzer

The Krüss DSA 100s Drop Shape Analyzer in Cleanroom A-1

The Krüss DSA 100S Drop Shape Analyzer will analyze the shape of a drop of liquid on a surface, or suspended from a needle, in order to calculate the contact angle, or the surface tension, respectively. It is mostly used to determine the contact angle of water as a measure of the hydrophobicity/hydrophilicity of the sample surface.

The user manual, user APV(s), technical information, and contact information can be found in LabManager:

An overview of the performance of the Drop Shape Analyzer

Purpose	Imaging and analysis of of the shape of the interface between liquid and air	Measurement of contact angle between sample surface and liquid Measurement of surface tension of liquid
Performance	Measurement accuracy	Highly dependent on analysis conditions (image quality and fitting model) and method used; usually around ±0.5°. Using several measurement points is recommended.
Process parameters	Available liquids	Syringe 1: Water (H₂O) Syringe 2: Diiodo-methane (CH₂I₂) Manual dispense is also possible
Sample requirements	Substrate material allowed	In principle all materials allowed in cleanroom
	Substrate size	Up to 6" wafers. In order to measure, a few mm² of flat surface is required.
	Batch size	One sample at a time
