Here are the 5 most frequently asked questions  regarding the Aquasonic 100 Ultrasound Gel (250ml / 0.25 Liter dispenser bottle).

1. Will Aquasonic 100 stain clothing or damage ultrasound equipment?

No. Aquasonic 100 is a completely aqueous (water-soluble) formula. It will not stain patient gowns or clothing, and it is entirely safe to use on delicate medical equipment. Leading global manufacturers of medical ultrasound equipment actively recommend it because it won't damage or degrade ultrasound transducers (probes).

2. How long can a 250ml bottle be used after it has been opened?

While testing shows that unopened Aquasonic 100 maintains its antimicrobial preservative effectiveness for over 5 years, general clinical guidelines recommend discarding an opened bottle after 28 days. Because the 250ml bottle is non-sterile and frequently handled, the 28-day rule helps facilities prevent environmental cross-contamination, regardless of whether the gel is kept at room temperature or in a gel warmer.

3. Is the gel safe for patients with sensitive skin or allergies?

Yes, it is highly tolerated. The formula is specifically engineered to be hypoallergenic, non-irritating, and non-sensitizing. Furthermore, it is completely paraben-free and formaldehyde-free, minimizing the risk of allergic reactions or skin irritation during both diagnostic and therapeutic procedures.

4. Can this specific 250ml bottle be used for sterile procedures?

No, the standard 250ml dispenser bottle is non-sterile. While the gel formula contains bacteriostatic properties to inhibit bacterial growth, the bottle itself is intended for routine, non-invasive diagnostic and therapeutic ultrasound procedures. For procedures requiring strict sterility (such as biopsies, needle aspirations, or surgical settings), Parker Laboratories manufactures separately wrapped, single-use sterile foil packettes.

5. Does the gel contain salt, and can it be used as a spermicide?

No to both. Aquasonic 100 is completely salt-free, meaning it won't dry out prematurely or cause abrasive wear to equipment. Additionally, it is not a spermicide and is not formulated to interfere with sperm motility, making it safe for use in routine OB/GYN or reproductive health imaging where a high-viscosity coupling medium is required.
