Bacterial Filter Tester G299
G299/ Bacterial filtration tester is suitable for medical surgical masks: it is used to cover the mouth, nose and mandible of the user to prevent microorganisms.
1.The machine consists of two parts: mechanical and electrical, It includes negative pressure cabinet, gas path and bracket.
2.Touch screen easy operation with USB interface to support data transfer, calibration can be carried through keyboard and USB interface.
3.Test principle: a certain concentration of bacterial aerosol accurs at upstream of the mask, entering the aerosol chamber and mix, the bacterial aerosol enters into two parallel gas path sampling system. One adds test sample to the sampler and other one does not add samples as positive quality control (total bacterial count). The ratio between the positive quality control value and the sample test value is the fifiltration effiffifficiency.

FAQ
(1) What is the testing purpose of the Bacterial Filter Tester?
The Bacterial Filter Tester G299 is used to measure bacterial filtration efficiency (BFE) of medical surgical masks and protective filtration materials.
(2) How does the Tester calculate bacterial filtration efficiency?
The Bacterial Filter Tester uses a dual-path sampling method. A bacterial aerosol is generated upstream of the mask sample and divided into two channels. One channel passes through the test sample, while the other serves as a positive control. The ratio between bacterial counts from both channels is used to calculate filtration efficiency.
(3) What products can be tested with the Tester?
The Bacterial Filter Tester is mainly used for medical surgical masks, disposable medical masks, and other protective filtration materials. It is suitable for manufacturers, research laboratories, and inspection organizations that need to evaluate bacterial filtration performance and verify whether products meet medical mask standards.
(4) Which standards does the Bacterial Filter Tester comply with?
The Bacterial Filter Tester complies with major mask testing standards, including YY0469-2011, YY/T 0969-2013, ASTM F2101, ASTM F2100, and EN 14683.
(5) What advantages does the Bacterial Filter Tester provide for laboratories?
The Bacterial Filter Tester G299 provides stable testing conditions through a negative pressure cabinet, accurate results through a dual sampling system, and convenient operation through a touch screen interface. Its USB data transfer function and calibration capability make it suitable for routine quality control and professional laboratory testing of medical protective products.
