    Mask Tester Experimental System Of Microbial Penetration In Dry State For Operation Sheet


    Experimental System Of Microbial Penetration In Dry State For Operation Sheet, Operation Clothes And Clean Clothes

    The ZR-1070 system consists of gas source generation system, detection main body, protection system and control system.

    It is composed of a series of components, which are used for the dry state microbial penetration test of operation sheet, operation clothes and clean clothes.

    Face Mask Detector Technology Advantage

    • Negative pressure test system, with fan exhaust system and high efficiency filter in and out of the air, to ensure the safety of operators;

    • Special operation software, with software parameter calibration, fault detection and automatic protection function;

    • Industrial grade high brightness color touch screen;

    • High brightness lighting lamp is built in the cabinet;

    • Built in leakage protection switch to protect the safety of operators;

    • The inner layer of the cabinet is made of stainless steel, and the outer layer is sprayed with cold-rolled sheet;

    • Heat preservation and flame retardant between inner and outer layers;

    • The front opening and closing glass door is convenient for the experimental personnel to observe and operate;

    • Detachable support, easy to handle;

    • Support and move the dual-purpose caster.

    Bacterial Filtration Efficiency and Particle Filtration Efficiency are probably the most important tests to be conducted on medical textile products such as surgical masks, gowns or caps, as well as on air filters.

    The BFE test is meant to measure the resistance of the materials and components of above described medical devices to bacteria penetration.Reported as percent efficiency, the higher the number,According to Annex B of EN 14683:2019, BFE is tested a the more effective the barrier.

    BFE Testing Method

    As follows:

    A specimen of the mask material is clamped between a six-stage cascade impactor and an aerosol chamber.

    An aerosol of staphylococcus aureus is introduced into the aerosol chamber and drawn through the mask material and the impactor under vacuum.

    The bacterial filtration efficiency (BFE) of the mask is determined by the number of colony forming units that pass through the medical face mask material, which are expressed as a percentage of the number of colony forming units present in the challenge aerosol.

    The BFE of the medical face mask shall conform to the minimum value given for the relevant type of mask.

    In products such as masks, frequently consisting of two or more components –usually with different composition-, each layer is tested separately. The lowest performing layer is the one determining the BFE value for the whole product comprehensively.
