The Class 4 indicator is designed to check whether sterilization conditions are being maintained in the sterilization pouches, which ensure that all equipment and instruments used in the medical, dental, health and other clinics are safe and clean.

Class 4 indicator, as validated by NAMSA laboratory, meets three parameters determining effectiveness of steam sterilization including time, temperature and the presence of steam, according to the company.

GS Medical Packaging general manager John Sherlock said a pouch with Class 4 indicators already built in saves the market the cost of manually inserting them each time.

"Luckily, our plant is equipped with industry-leading technology that allows for us to produce these integrated pouches with the highest quality controls," Sherlock added.
