Question: 1 / 400

What is the recommended pH range for enzymatic cleaners used in reprocessing?

4 to 6

6 to 8

Enzymatic cleaners are specifically formulated to aid in the removal of organic material from medical instruments, including endoscopes. The effectiveness of these cleaners is closely tied to the pH level of the solution. The recommended pH range of 6 to 8 is optimal for enzymatic activity, as enzymes typically function best in a near-neutral pH environment.

In this range, the enzymes can effectively break down proteins, fats, and carbohydrates, ensuring thorough cleaning prior to disinfection or sterilization processes. If the pH is too low (acidic) or too high (alkaline), it can denature the enzymes, leading to reduced effectiveness and potentially leaving residual contaminants on the instruments. Thus, maintaining the pH within the 6 to 8 range is critical for achieving optimal cleaning outcomes in endoscope reprocessing.
