Information

　　OPA is a new high level disinfectant. Compared with glutaraldehyde, OPA has the advantages of broad spectrum and high efficiency, no need to activate when it is used, simple preparation, no inhalation toxicity and mucosal toxicity, and good stability in continuous use. It can be used continuously for 14 days, and the validity of the stock solution can be up to 2 years. At present, it is mostly used for endoscope disinfection.

The technical code for disinfection of medical institutions requires that phthalaldehyde should be sealed and kept away from light in a cool, dry and ventilated environment. How long is the validity period after opening? At present, there is no relevant regulation, because OPA has excellent stability in a wide pH range (ph3-9). Therefore, after opening, it can be used within the validity period marked on the product. We can also study the period of validity of OPA after it is opened, and explore more scientific and credible results. From the perspective of management, it is more important to pay attention to the standardized storage and use after opening to ensure the disinfection effect.
