Vaporized Hydrogen Peroxide (VHP) is a widely acknowledged sterilizing agent, especially in enclosed filling isolators due to its potent oxidizing properties. As the use of isolators becomes more prevalent, there is a growing demand for robust samplers that can endure the harsh environments created by VHP. The MiniCapt Pro Remote Microbial Sampler is specifically engineered with an internal flow path that can resist the corrosive effects of VHP, addressing the need for durable sampling instruments. Samplers exposed to VHP often encounter issues such as internal surface corrosion, reduced lifespan, and a lower mean time to failure (MTTF). To combat these challenges, preventative measures have been implemented in the MiniCapt Pro samplers. These samplers underwent thorough testing, including exposure to both static and full-cycle VHP while in operation. Results from the tests were meticulously evaluated against calibration criteria and found to be well within acceptable limits. The test outcomes showcase that the MiniCapt Pro instruments are well-suited for environments where frequent exposure to aggressive cleaning and sterilization methods like VHP in isolators is standard practice. By enhancing the resistance of the samplers to the corrosive nature of VHP, the MiniCapt Pro Remote Microbial Sampler contributes to improving sterilization efficiency and ensuring reliability in critical environments.
