DROPimage Advanced  

The DROPimage Advanced software measures contact angle, surface energy and surface and interfacial tension. The drop shape method is determined by a contour fitting algorithm, and the profile coordinates are used to calculate the surface tension, contact angle and the area and volume of the drops. Calculation of surface tension is done by means of a method based on a least squares fit to theoretical profiles produced by a numerical integration of the Young-Laplace equation. The methods have been published in J.Colloid Interface Sci.

DROPimage Advanced ships with the ramé-hart Advanced Goniometer / Tensiometer (Model 500) as well as Model 250, Model 290, and Model 590 and is offered as an upgrade for users of DROPimage Standard and those with the now-retired RHI software. Previous versions of this software, which was originally called DROPimage, can also be upgraded to DROPimage Advanced. Contact us for pricing.

DROPimage Advanced includes all of the tools and features that are included in in DROPimage Standard but features additional commands and tools. The following are features that are unique to DROPimage Advanced and are not part of DROPimage Standard:

• The Automatic Measurement of Surface / Interfacial Tension from Sessile drops and bubbles

• Automatic time controlled experiments

• Support for the Automated Tilting Base option

• Static and Dynamic Surface Tension measurements

• Relaxation*

• Oscillation with Surface Elasticity Calculations with support for the Oscillator option*

• Image Save and Recalculation Features

• Video Replay

• Event and Pulse-drive Experiments*

• Batch Experiments

• Constant Volume or Area*

• Report Generation

• Graphing and Plotting

The first video shows how easy it is to calibrate DROPimage Standard using our 4mm Calibration Tool (p/n 100-27-31-U).

The video below shows how the Experiment Wizard in DROPimage Advanced can be used to measure surface tension.

The video below show how drops on superhydrophobic surfaces can be measured using DROPimage Advanced.

The following video shows the measurement of dynamic contact angle on hydrophilic surface (requires optional Automated Dispensing System).

The video below shows how the measure distance command is used in DROPimage Advanced to capture the distance between two points.
