Permeation tubes suppliers
WebOct 7, 2009 · Dynacal® Permeation Tubes are inert capsules containing pure chemical compound in 2-phase equilibrium between gas phase and liquid or solid phase. At constant temperature, device emits compound through permeable portion at constant rate. Accurate, stable concentrations range from PPB to high PPM. WebEntegris low-permeation tubing features a high-purity, corrosion-resistant PFA inner layer combined with a permeation-resistant outer layer of CPT. The multilayer tubing reduces chemical permeation through the tubing and into the environment Suited for a wide range of applications, from semiconductor to chemical process industries Specify Your Part
