Penetration and Filtration
The BPT-02 and PFT-02 devices test the penetration and filtering properties of fabrics, filters and face masks.
Test of Fabrics, Filters and Face Masks

BPT-02
Properties:
- Penetration of blood into medical tissue
- Immigration of synthetic blood through negative pressure into the fabric
- For flat fabrics such as mask gowns, surgical gowns, etc.
Advantages:
- Easy to perform
