At Parker, product quality and reliability by adhering to the strictest quality control/infection control guidelines with each and every line. Furthermore, Parkers’ commitment to quality is nowhere more evident than ever in the flagship, Aquasonic 100 Ultrasound Transmission Gel.
In response to inquiries made regarding possible microbial contamination, the following information is provided:
Parker Laboratories products meet the USP criteria for Antimicrobial Preservative Effectiveness.
Studies performed on Aquasonic 100 Ultrasound Transmission Gel show that the product remains free from microbial growth for more than five years from date of manufacture.
During the course of a 28-day study, samples of Aquasonic 100 were stored both at room temperature, and at 36 – 38°C to simulate conditions in a Thermasonic® Gel Warmer.
Samples under both conditions met the USP criteria for preservative effectiveness. As long as a bottle that has been opened is stored properly and not contaminated during use, the gel is expected to maintain its original shelf life.
Since there is no effective way to determine whether an opened bottle of gel has been contaminated general guidelines are that gel should be marked to expire 28 days after opening. Using a warmer for the gel does not impact the expiration time.
