  • ZR-1013 Biosafety cabinet quality tester

    ZR-1013 Biosafety txee zoo tester

    ZR-1013 Biosafety cabinet quality tester adopts potassium iodide (KI) method to test the protection performance of biosafety cabinet class II, conforms to JJF 1815-2020 <Calibration Specification for Class II biosafety Cabinets> and related standards. Build in background test, operator protection, product protection and cross protection four working mode. It is meanly used to test whether the aerosol leaked to outside of the environment, whether the outer agents could enter the work area, whether the contamination among samples is minimized. It is applicable to the protection performance test of class II biosafety cabinets by metrological verification departments, scientific research institutes and biosafety cabinet manufacturers.

  • ZR-2021 Large flow airborne microbe sampler

    ZR-2021 Cov dej ntws loj hauv cov pa microbe sampler

    ZR-2021 Cov dej ntws loj hauv cov pa microbe sampler tau thov rau lub tshuab pa microbene sau. Cov khoom lag luam muaj ntau theem ntawm kev sib piv cov taub hau, tuaj yeem sau cov tshuaj aerosol thiab tshem tawm cov khoom loj dua 12 μm thiab me dua 2 likem zoo li hmoov av, pollens thiab lwm yam. Sau cov khoom nqus tau ntawm 2μm txog 12 μm thiab mloog zoo rau cov cua nqus, tom qab ntawv sau los ntawm cov sampler sab.

  • ZR-2050A Airborne microbe sampler

    ZR-2050A Airborne microbe sampler

    ZR-2050A airborne microbe sampler yog qhov ua tau zoo ntawm ib theem ntau aperture cuam tshuam sampler, qhov ntsuas qhov ntsuas ntawm Anderson impacting txoj ntsiab cai, cuam tshuam nrawm yog 10.8 m / s, nws tuaj yeem ntes txhua qhov loj dua 1 1μm. Qhov ntsuas no yuav nqus cua los ntawm ntau lub aperture sampling lub taub hau, cuam tshuam rau Φ90mm petri phaj, huab cua microbes yuav raug ntes rau agar nruab nrab. Qhov ntsuas no tau dav dav hauv kev lag luam kws kho mob, kev lag luam khoom noj khoom haus, lub koom haum tshuaj xyuas tshuaj, chaw tiv thaiv kab mob, kev tiv thaiv kev noj qab haus huv thiab kev kis mob, tsev kho mob thiab lwm yam kev lag luam thiab cov tuam tsev.
