Introduction The Membrane Flow Analysis Device for Gas (MFAD-G), Quality Control Model, is the first* of a 3-version series of devices that, altogether, will allow use-specified measurement of flow rate and flow pressure of gas and liquid media through chip-mounted membranes. The QC Model has a rudimentary form of the general system and acts as…
How to use the McGrath Lab Surface Contact Angle Goniometer (SCAG) to collect image data for the established uses. Please refer to the SCAG Setup Protocols for assembly instructions. Note that the details of established uses will be covered in a future post. General Notes Instrument Layout (See Protocols for SCAG Setup for more part…
How to prepare the McGrath Lab Surface Contact Angle Goniometer (SCAG) from a disassembled form. I will create detailed posts on potential uses in the future. GENERAL NOTES Based on the McGrath Lab SCAG as it was on May 16th, 2013 Instrument layout: All bolts and set screws are 1/4-20’s. The angle screws are 10-32’s. Loosely =…
With the goniometer nearly finished, I’d like to share a look at what has been created: Introduction A surface contact angle goniometer (SCAG) measures the angle(s) of contact that a droplet of liquid makes with a surface. This particular SCAG does this by creating a shadow that is isometric with the droplet and recording its…
