Gel Swelling Instrument
We are using a SwellRatio Tester (SRT-1™) from Cambridge Polymer Group, Inc. forcharacterizing the swelling of polymer gels. The instrument uses a lightweightprobe that sits on top of the sample, and as the gel swells/deswells thevertical position of the probe changes. The probe partially blocks the beam ofa laser micrometer, and when the probe moves up or down (due to theswelling/deswelling of the gel) the change in probe position is measured by themicrometer. The instrument is equipped with a temperature control unit, and canbe used to do both temperature scans and to measure swelling over time at aconstant temperature.
