How to Ensure Accurate Testing with the GT-RA02 BFE Tester

The GT-RA02 Mask Bacterial Filtration Efficiency Tester is an advanced device specifically designed to accurately measure the bacterial filtration capacity of masks. Its efficient and reliable testing process makes it the preferred tool for mask manufacturers, research institutions, and quality testing departments. This article will detail the operation steps of theMask Bacterial Filtration Efficiency (BFE) Tester, helping you conduct testing efficiently and safely.

1. Preparation Stage
Before conducting any tests, users need to be well-prepared. First, perform a safety check on the Mask Bacterial Filtration Efficiency (BFE) Tester to ensure it is stable and securely connected, with a safe power supply. Next, prepare the experimental materials, including standard petri dishes, bacterial suspension, and the Andersen sampler. Add the specified reagent to the petri dishes and install the Andersen sampler in sequence to ensure all materials are ready before starting the experiment. Additionally, ensure that the operating environment is sterile to avoid any potential contamination.

2. Equipment Startup and Disinfection
Starting the Mask Bacterial Filtration Efficiency (BFE) Tester is a critical step in the testing process. Users need to connect the power line and air compressor, turn on the air compressor, and set the air pressure to 0.2Mpa. After starting the equipment, turn on the control panel power, and sequentially start the fan, lighting, and UV lamp for disinfection, with a suggested disinfection time of no less than 30 minutes. During disinfection, wear gloves and prepare the bacterial suspension, petri dishes, and sampler. After disinfection, quickly place the experimental materials in the safety cabinet to maintain a sterile environment.

3. Testing Operation and Data Processing
Once preparation and disinfection are complete, users can proceed to the formal testing phase. Open the Andersen sampler, quickly place the test samples and petri dishes inside, and clamp them in sequence, ensuring the lid of the petri dish is inverted to prevent microbial contamination. In the parameter settings, users need to set the relevant testing and disinfection parameters, then click "Start" to enter the equilibrium stage. Once fog is observed, confirming the device is stable, the formal test can begin. After the test is completed, the system will automatically conduct air cleaning. Users should retrieve the petri dishes and incubate them in a biochemical culture cabinet at a constant temperature of (37±2)℃ for 24-48 hours, and then process and analyze the data according to the standard test methods.
