Rame hart goniometer manual

Model supports and includes an 8" wafer support and other sizes can be added. Models , , , and support the 4" wafer support only.

Larger supports may require an upgrade kit which will extend the working distance of the camera and extend the microsyringe fixture. We offer kits which include all of the necessary parts. The 6" or 8" diameter rotating Vacuum Chuck Support holds down large films and other flexible substrates while surface studies are performed. Supported on Models , , and Vacuum source is required. The Vacuum Chuck is supported on the following underlined models: 90 This accessory maintains flatness and position of lead frames in order to achieve accurate contact angle measurements.

Precise positioning of each testing surface is accomplished with ease. This support mounts directly to the stage of the Contact Angle Goniometer. Size requirements for various lead frames are easily accommodated by our manufacturing facility. The Lead Frame Support is supported on the following underlined models: 90 Many of the legacy instruments, in particular Model with a manual microscope, are still in use.

In order to provide a firm quotation, we suggest you email us a snapshot of your system so we can determine if any other upgrades or components are necessary in order install the kit.

Please contact us for further details and current pricing. Please contact us for details. The microsyringe fixture facilitates rapid and precise formation of pendant and sessile drops. Following placement of a sessile drop, the syringe is easily swung from the field of view. It will return to its exact working location for placement of the subsequent drop.

Alternatively, it can remain at the working location, allowing the user to continuously add or withdraw fluid from a sessile drop for the purpose of forming advancing or receding contact angles.

The Rame-Hart Goniometer is a metrology tool for computer-aided contact angle and surface energy measurement and analysis. The system uses a manual liquid dispensing syringe which can be easily exchanged to test different liquids. The DROPimage advanced software package allows for analysis and capture of images and data for static, advancing and receding contact angle measurements in addition to surface energy calculations.

The DROPimage Standard software measures contact angle and includes a suite of surface energy tools including:. The Rame-Hart Goniometer is designated as a General class tool.

Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances.

Today over six decades of experience and innovation can be found in every product we sell. That is our sole focus. Our machinists and instrument technicians hand build and assemble each unit to rigid specifications. No instrument will ship from our facility until it has been thoroughly tested and calibrated and every component is in proper working order. Note that in September Model was discontinued but replaced by Model The only difference is the software.

Model shipped with the DROPimage Standard software contact angle and surface energy while Model ships with the new DROPimage Pro contact angle, surface energy, surface tension, and interfacial tension. A wide variety of needles are available. See our chart here: www. The optional software-driven Automated Dispensing System is supported on all models. In surface science, an instrument called a contact angle goniometer is used to measure static contact angle, advancing and receding contact angle, and in some cases, surface energy.

The root goni refers to "angle" while meter refers to measuring device. Thus a goniometer is a measuring device for angles. While the term has been used to describe a tool used by physical therapists and also for measuring other types of angles, the traditional and more prominent use of the word "goniometer" has been to describe a contact angle meter.

All of our current models, except Model measure both surface tension as well as contact angle and surface energy.
