Product Overview

The KR‑2517 bacterial filtration efficiency tester is dedicated lab‑grade equipment for evaluating bacterial barrier performance of medical‑grade mask materials. It generates standardized microbial aerosol challenge, passes the bacterial‑laden mist across mask specimens, and calculates BFE value by comparing upstream and downstream bacterial colony countsASTM Inter….

The unit integrates bio‑aerosol generator, aerosol mixing chamber, negative‑pressure biosafety cabinet and dual‑channel six‑stage Anderson cascade samplers. The whole test sequence runs under microcomputer automation. This instrument meets YY 0469‑2011, ASTM F2100, ASTM F2101 and EN 14683 test clauses. It is widely deployed in medical‑mask manufacturers, medical‑device inspection agencies, material‑research institutes and accredited third‑party PPE‑testing laboratoriessalesxhins….

Core Product Competitive Advantages

1. Negative‑pressure enclosed biosafety cabinet design Full negative‑pressure containment prevents microbial aerosol leakage during testing, protecting lab personnel from bio‑hazard exposure. Transparent front glass door allows real‑time visual observation of internal test progress without opening the cabinet. Internal illumination facilitates sample‑setup inspection.
2. Dual‑channel six‑stage Anderson cascade sampling system A‑B dual independent sampling paths are fitted inside the cabinet. The built‑in adjustable‑speed peristaltic pump precisely controls bacterial‑liquid atomization flow. Each sampling channel maintains standard 28.3 L/min sampling flow rate for accurate graded particle collection.
3. Precision‑controlled microbial aerosol generation module Mass‑flow‑regulated aerosol nebuliser delivers stable bacterial‑mist output. It produces target median aerosol particle size of 3.0 ± 0.3 μm with geometric standard deviation ≤1.5, fully matching international BFE test‑particle‑size requirements.
4. Industrial touch‑screen intelligent control & USB data export High‑brightness colour touch‑screen manages all parameter configuration, real‑time status monitoring and process logging. USB flash‑disk data‑dump function saves full‑run test datasets for later report compilation and lab‑archiving purposes.
5. Complete multi‑layer electrical safety protection Equipped with built‑in electric‑leakage protection circuit, emergency‑stop button and over‑pressure safeguard. Oil‑free vacuum pump with silencer unit ensures low‑noise stable airflow, improving long‑duration lab‑testing comfort. Mobile lockable casters support convenient on‑site repositioning.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Position main unit on level lab ground and lock casters. Complete power‑supply connection. Prepare bacterial suspension liquid, agar culture plates and mask test‑specimens. Set aerosol‑flow, peristaltic‑pump rate and sampling‑time parameters via touch‑screen. Check negative‑pressure cabinet sealing status.
2. Specimen & Sampler Setup Mount mask‑material specimen onto sample‑clamping fixture inside the negative‑pressure chamber. Install six‑stage Anderson samplers with prepared agar plates for upstream‑downstream bacterial collection. Close and latch the front glass cabinet door.
3. Launch Automated BFE Test Start test program. Microbial aerosol generator produces standardized bacterial mist. Aerosol flows through aerosol mixing chamber and passes across test‑specimen. Dual‑channel samplers collect bacterial particles on agar plates under regulated sampling‑flow. Whole‑process negative‑pressure containment stays active.
4. Post‑Sampling Plate Retrieval When preset sampling duration completes, aerosol generation and vacuum‑sampling stop automatically. Release cabinet negative‑pressure safely. Take out Anderson samplers and retrieve agar plates for subsequent constant‑temperature incubation and colony‑counting work. Calculate final bacterial‑filtration‑efficiency value according to colony‑count results.
5. Post‑Test Tidying Clean aerosol pipeline and cabinet interior to eliminate residual bacterial‑liquid contamination. Power‑off instrument. Conduct regular maintenance for nebuliser, peristaltic‑pump and vacuum‑pump components.

Safety‑Operation‑Reminder

Strictly follow microbiological‑lab biosafety protocols during bacterial‑aerosol testing. Confirm cabinet negative‑pressure function works properly before starting each test‑run. Do not open front glass‑door while aerosol‑system is active. Regularly clean aerosol pipelines to prevent bacterial residue accumulation. Ensure reliable equipment‑grounding before power‑on.
