Features

PGX+ Measuring Head is a video based instrument designed for quality control applications. This model has all the features of model PG3, with the addition of an automatic application of the droplet. In addition this model can test specimens of "any size" as it does not require cutting of samples.

The integrated pump delivers accurate droplets in steps of 0.5 μl and the built-in camera captures single droplet images to determine the static contact angle at "equilibrium" or a sequence of images to measure the dynamic wetting, rate of sorption and spreading as a function of time. The PGX+ software measures surface tension of the test liquid, calculates the surface energy of a solid and includes a report generator. The PGX+ is connected directly to the USB port of a laptop or a desktop computer.


  • Very small footprint - 90(L) x 55(W) x 90(H) mm
  • Integrated camera - Captures 80 images/second (640 x 480 pixels)
  • Remote Control from PC Keyboard
  • Integrated pump - Delivers precise droplets in 0.2 μl steps
  • Automatic Droplet Application - Static and Dynamic Mode
  • Runs on most PC & Laptops (USB)
  • Easy to install and transport - no hardware to fit inside computer!
  • User-friendly software for Windows 10 (64 bit), Windows 7 (32/64-bit), XP, Vista (32/64-bit)
  • Multiple language user dialogue
  • Free Software Updates
  • Complies with test method Tappi T458, ASTM D 724, ASTM D 5946

PG Dosing Unit

This testing instrument is used to determine the interaction between a liquid droplet and a surface. Liquid droplets can be applied by means of a manual dispenser (syringe) or in some of the models an integrated miniature pump.

When tacky liquids or many different liquids are used, it is necessary to clean or replace the liquid system to avoid contamination

Concept

top

The new concept ‘Disposable Liquid System’ is an attractive alternative to tedious cleaning and replacement of expensive parts. In addition the new PG Dosing Unit will offer new opportunities not yet available with the standarrd instruments.

 

The PG Dosing Unit is based on a standard syringe pump for low-cost disposable syringes. The complete liquid system consists of a one mL syringe, a dispensing tip and a PTFE tubing. This standard syringe produces more than two hundred liquid droplets of four microlitres and when the syringe is emptied or not required any more, the entire liquid system is disposed of. A new syringe is then filled with the new test liquid, a new dispensing tip with tubing is attached and the syringe is put intoi the PG Dosing Unit. Disposable items like syringes, dispensing tips and PTFE tubings are offered in economical bulk packages.

The PG Dosing Unit can be operated in many modes. The most comon use is to set the pump to a preset droplet volume and pump out a new droplet for each new test position. The PG Dosing Unit can also be programmed for sophisticated analysis of the “wetting hysteresis” using the advancing/receding contact angles to characterize the surface properties.

Here the dynamic contact angle is measured as the droplet advances across the test surface (top view). The pump flow is then automatically reversed at a user-defined volume and the liquid droplet is now receding on the surface (center view). Finally the droplet will release from the dispensing tip (bottom view) and the test is aborted.
