GLY-16 Glycerin 

Ultrasonic Couplant 

Glycerin can be used as a general purpose couplant. The viscosity and acoustic impedance are desirable for rough surfaces and highly attenuating materials. Glycerin has an acoustic impedance of 2.42 x 105 gm-cm2 /sec.

Glycerin is also suitable for use in high frequency delay line inspections, high frequency delay line thickness gaging and contact transducer testing on reference standards.

All packaging is approved to United Nations shipping standards for air shipment. Glycerin can be corrosive to carbon steel and aluminum and can reduce the sensitivity of subsequent dye and flourescent penetrant inspections. High purity Glycerin (98.2% or higher) increases in viscosity with decreasing temperature. To pump glycerin, store above 65˚ F / 18˚C.
