Dynatron Lotion is a high-quality lotion for those who prefer lotion as an alternative to ultrasound gel. Use it as a coupling agent to allow ultrasonic waves to pass out of the ultrasound transducer head into the patient's body tissue. This water-soluble lotion can be massaged into the skin after ultrasound treatment. It is made with a hypoallergenic and bacteriostatic formula. It also contains no salt, alcohol, or dye. The light lemon scent offers a nice aroma after applied. Available as a case of four 1-gallon bottles.
