Dropometer Surface Analysis System from Droplet Lab

Surface science is the study of materials at interfaces such as air-liquid, air-solid, or solid-liquid.  Questions such as surface wetting, emulsion stability and release of active ingredients require complete characterization and surface analysis of the surface’s active properties in order to optimize performance of materials such as liquid detergents and treatment of surfaces in microelectronics and printing applications. 

The Dropometer is a small-scale, easy-to-use surface analysis system that utilizes the high-resolution images possible with a smartphone camera and the computing power in order to carry out the detailed fitting and modeling necessary to reduce the image data to surface properties.  This ingenious laboratory instrument has application in a wide range of laboratories and production site to guide formulation of a number of products. 

Droplet Lab

How does it work?

Running on smartphone technology all your surface tensiometry (e.g. surface tension and contact angle) needs are met

Prepare

Prepare solution and load syringe and start Droplet App

Measure

Introduce the droplet as a hanging droplet or as a surface droplet and capture the image.

Calculate

Calculate the result. The image and results are immediately store in the secure cloud.
