About Ziemer Chromatographie

Ziemer Chromatographie GmbH has been supplying laboratories with consumables and accessories for chromatography and instrumental analysis since 1984. The product range includes market-standard separation columns for GC, GPC, LC, HPLC and UHPLC as well as capillary electrophoresis (CE) from all well-known manufacturers, sample vials and closures, syringes and needles, septa and O-rings, sample preparation products, as well as tools and aids for the analytical laboratory. In-house production comprises the manufacture of polyurethane foam filters (PUF) for gas sampling in many dimensions, both uncleaned and cleaned. Services include the regeneration of used GC liners as well as surface treatments of glass: silanization (Sil, PM-Sil, INNO-Sil), siliconization and HCl treatment. The company is an authorized specialist dealer of leading manufacturers such as IDEX, Trajan, Thermo Scientific, VICI and RESTEK. The company is headquartered in Langerwehe in the district of Düren.
