Product Details
SJ-X100 Medical Face Mask Filter Tester BFE Testing Machine
Face Masks bacterial filtration efficiency BFE tester is to
determine the bacterial filtration efficiency (BFE) of medical face
mask materials by employing a ratio of the upstream bacterial
challenge to downstream residual concentration of the tested
medical face mask materials.
Features of BFE filter tester

filter, 100% safe discharge
- Use two-way six-level Anderson sampling;
- Built-in peristaltic pump with adjustable flow rate;
- Special microbial aerosol generator, adjustable spray flow of
bacterial liquid, good atomization effect;
- Industrial grade 10.4-inch color touch screen control, make the
operation is simpler;
- Microcomputer is used for control and data processing, which can be
seamlessly connected to the laboratory information management
system;
- USB interface, support data transfer;
- The safety cabinet has built-in LED lighting for easy observation;
- Built-in ultraviolet UV disinfection lamp;
- The front-opening sealed glass door is convenient for operation and
observation;
- Use imported isolation operation gloves, safe and reliable;
- The system has functions of user authority management and audit
trail;
