Buyer's Guide

Why choose this model?

The Model 90 Pro combines our entry-level bench with DROPimage Pro software for a low-cost system that can measure static contact angle, surface energy, and surface/interfacial tension. In-software control of the Automated Dispensing System is also available as an optional upgrade.

Suggested alternatives

For a more durable bench construction with easier repositioning and more advanced upgrade options, consider the Model 210. If you need to study wetting and perform dynamic contact angle measurements, consider an instrument with DROPimage Advanced, such as the Model 250.

All ramé-hart systems are supplied as fully functional turn-key systems, with a PC, pre-installed and configured software, and the components and tools needed to set up and operate the instrument. Compatible accessories and software upgrades can be added later as your needs grow.
