Meets high performance ultrasound transmission standards while protecting and moisturizing skin. Its viscosity is optimized for OB, radiology and vascular ultrasound. Also available in a low viscosity scanning gel. Minimizes refraction of sound beam when entering skin by matching gel sound velocity to skin velocity with. Acoustic properties minimize refraction - optimize coupling Proprietary manufacturing process produces air-free gel - which virtually prevents artifacts Contains 24% Aloe Vera gel to protect and moisturize skin Meets fragrance-free requirement of major ultrasound system manufacturers Gentle, non-irritating formulation won't harm patient's or sonographer's skin Contains no dyes, fragrance, silicones, alcohol, surfactants, or mineral oil to harm the transducer Antimicrobial formulation will not support yeasts, molds or other challenge organisms Available in 8 oz bottles and 5 L containers
