Liquid dispensing system with disposable/replacable parts

The PGX+ PocketGoniometer applies test liquid droplets via an integrated miniature pump. When particularly viscous liquids, or several different types are used, it is necessary to clean or replace the internal liquid system to avoid contamination. The PGX Dosing Unit has a disposable element that remove the need to tedious clean or regularly replace expensive parts.

The PGX Dosing Unit system includes a pumping unit, a 1ml syringe, a dispensing tip and PTFE tubing.

The syringe produces < 200 liquid droplets of 4 micro-litres and when emptied, or no longer required, the complete liquid system is thrown away and replaced.

The PGX Dosing Unit has several settings. These include a simple pump pre-set droplet volume, to a sophisticated program for analysis of the “wetting hysteresis”, using the advancing/receding contact angles, to characterise the surface properties.
