Immersion frit body for connection to the eluent suction line for direct fine filtration of HPLC eluents during suction into the pumping system to protect seals, pistons and column packings from early wear due to contamination. Preferably for use in chromatography of instable macromolecules and bioactive substances as well as for ion chromatography.
Cylindrical hollow frit body made of sintered 99.9 % purest titanium, a metallic material combining chemical resistance and biocompatibility. Nozzle also made of purest titanium, with PTFE seal fitted in the frit body. Nozzle outside diameter 1/8".
Frits made of plastic, titanium, Hastelloy and proven material composites, high-pressure resistant, for 1/4" HPLC columns and other HPLC system elements, for prefiltration of eluents, particularly for use in the metal-free chromatography.
