Excellent Resistance to Fungus and Mold Growth: ISO 9022-11 Tested

Individual factors can cause a variety of effects on instrument performance. In general, a good manufacturing and testing process can ensure that the instrument is robust enough to withstand a wide range of environmental factors and that its performance will be maintained successfully during its lifetime. The final results from a rigorous ISO 9022-11 test of several microscopes from Leica Microsystems show successful resistance to mold and fungus.

The Division 4.1 of the BAM Federal Institute in Berlin, Germany, performed a rigorous mold and fungus resistance test, in accordance with the ISO 9022-11:1994 procedure (environmental test methods for optics and optical instruments: mold growth), for various microscope parts from Leica Microsystems, including objective lenses. The final results of the rigorous mold and fungus test clearly confirm that the Leica ES2, Leica EZ4, Leica EZ4 HD, Leica DM500, and Leica DM750 series microscopes successfully resist mold and fungus growth. Therefore, mold and fungus should have no effect on the performance of these microscopes. In addition to mold and fungus resistance, Leica Microsystems uses silver (Ag) based additives, such as AgTreatTMfor main touch-point plastic and painted components of some microscopes in order to inhibit the growth of bacteria. Also, it should be noted that the educational products from Leica Microsystems come with a warranty which covers fungus and mold.
