NE96

Needle sets for surface and interfacial tension

  • Bookmark

The choice of a suitable needle diameter maximizes the accuracy of surface and interfacial tension measurements using the Pendant Drop method.
For this purpose, the needle set NE96 contains stainless steel needles with a length of 38 mm and different outside diameters (0.5/1.0/2.0/3.0 mm), in order to achieve an ideal drop shape for analysis in every measuring range. In the set NE93, the four different needles are also PTFE-coated and optimize the analysis of liquids with good wetting properties. The coating prevents external wetting of the needle and ensures absolutely symmetrical drop shapes.
