radiello - Diffusive Body

Four kinds of diffusive bodies are available, with like outer dimensions: 60 mm height and 16 mm diameter. The white diffusive body, code 120, of general use, is made of microporous polyethylene 1.7 mm thick and average porosity 25 ± 5 µm. Diffusive path length is 18 mm. The blue diffusive body, code 120-1, has the same properties of the white one but is opaque to light: it is suited to the sampling of light-sensitive compounds. The yellow diffusive body, code 120-2, should be used whenever the sampling rate must be reduced; it is made of microporous polyethylene 5 mm thick and average porosity 10 ± 2 µm. Diffusive path length is 150 mm. The permeative diffusive body, code 120-3, is a 50 µm thick silicone membrane strengthned by a stainless steel net. It is employed for anaesthetic gases and vapours sampling.
