The main performance indexes of the ZR-1000A mask virus filtration efficiency (VFE) detector conform to the YY/T1497-2016 detection method of Phi-X174 phage for the evaluation of virus filtration efficiency of medical protective mask materials . The method of double gas path simultaneous comparison sampling improves the accuracy of sampling, which is suitable for the measurement and verification departments, scientific research institutes, mask manufacturers and other relevant departments to detect the mask virus performance detect of filtration efficiency.

300W Mask Particle Filtration Efficiency Tester, 0.075μm Mask Particle Filtration Efficiency Tester, 0.075μm face mask differential pressure tester.

ZR-1310 salt aerosol generator is a special instrument which produces aerosol particles of specific particle size and concentration after atomizing and drying NaCl solution of specific concentration with Collinson nozzle. It has built-in clean air compressor, drying device and multi nozzle regulating valve. Under the air flow of 100L/min-120L/min, the output aerosol concentration can reach 20 μg/L-100 μg/L, The particle size of the output aerosol is 0.02-2 μm, which is applicable to the leakage detection of masks, filter materials and high-efficiency filters by medical equipment inspection institute, disease prevention and control center, hospital, high-efficiency filter manufacturer, etc.

Large capacity and large opening of evaporating flask give larger evaporation surface. The evaporating flask keeps rotating when it is constantly heated by water bath, solvent evaporates more efficiently under cacuum condition.
