Echo Ultrasonics Glycerin Couplant is a versatile, general-purpose ultrasonic couplant packaged from 99+% USP glycerin. Its medium viscosity and high acoustic impedance make it especially effective on rough surfaces and highly attenuating materials, where water-based gels can struggle to transmit enough sound.
With an operating range of 65°F to 500°F (18°C to 260°C) and less than 50 ppm halogens and sulfur, it suits a wide range of flaw detection and thickness gauging work. This carton holds twelve convenient 4 oz (118 ml) bottles, ideal for stocking inspection kits and field crews.
Key Features
High acoustic impedance
Glycerin's high acoustic impedance transfers more ultrasonic energy into the part, giving stronger signals on rough, pitted surfaces and highly attenuating materials.
Medium viscosity fluid
The medium viscosity fills surface irregularities and stays where it's applied better than thin fluids, while still spreading easily under the probe.
Wide temperature range
It works from 65°F to 500°F (18°C to 260°C), with a boiling point of 555°F (290°C), so it can be used on warm and elevated-temperature parts.
Low halogens and sulfur
Total halogens and sulfur are each below 50 ppm, for applications where contaminant levels in the couplant matter.
Material compatibility
Glycerin has no corrosion effect on most plastics, fiberglass and composites. It can be corrosive to carbon steel and aluminum, so clean it off metal parts after inspection.
