Polysonic Ultrasound Lotion

Polysonic Ultrasound Lotion by Parker Laboratories is a multi-purpose acoustic coupling agent formulated for both diagnostic and therapeutic ultrasound. Unlike standard gels, this white lotion doubles as a massage medium, making it a favorite among physical therapists, chiropractors, and sonographers who move between imaging and hands-on treatment throughout the day.

The lotion's key advantage is its lubricity: it glides longer than conventional gels, so clinicians performing extended therapeutic sessions or massage-assisted ultrasound don't need to reapply as frequently. It's water-soluble for easy cleanup, non-staining, non-irritating, and safe for use with transducers when applied as directed.

Our collection carries the Parker Laboratories Polysonic Multi-Purpose Ultrasound Lotion in the practical 1-gallon size (item 21-28), supplied with a 250 mL (8.5 oz.) refillable dispenser bottle. The gallon format is built for busy practices—refill the bench-top dispenser as needed and keep the bulk container in storage, which lowers per-application cost compared with buying individual bottles.

A common question is whether Polysonic works for both diagnostic imaging and therapeutic modalities. It does; the "multi-purpose" formulation is engineered to maintain reliable acoustic contact across frequencies while offering enough slip for treatment work. Store it at room temperature, and warm bottles gently before use if patient comfort is a priority in cooler settings.
