he TC 100 is a highly inert and robust column for leaching tests. The sample tube is made out of acrylic glass. This improves acid-base property and increases thermal resistance. All parts, which are in contact with the sample, are made out of acrylic glass, PVDF and Viton. The TC 50 columns are equipped with 10 μm inlet and outlet nylon filters. The test columns was designed for using forLeaching Test and for similar applications ( NEN 7343, DIN 19528, DIN EN 14405 ).
