AirClean® Systems dead air boxes provide a circulation-free environment for the amplification and manipulation of DNA/RNA. Each dead air box is standard with the UVTect Microprocessor controller and a 254nm ultraviolet light source for irradiation between amplifications. A safety interlock switch disables the UV light when the sash is raised, preventing operator exposure. Use for mycology or other cleanroom application: cultivation, harvesting. Seamless design and UV-reflective construction materials further ensure no harmful UV energy escapes the enclosure.
