{"product_id":"ec-43-nucleodur-c18-gravity-sb-5-m","title":"EC 4\/3 NUCLEODUR C18 Gravity-SB, 5 µm","description":"\u003cp\u003eEC 4\/3 NUCLEODUR C18 Gravity-SB, 5 µm is an HPLC guard column for protecting analytical main columns in liquid chromatography. It has a length of 4 mm and an internal diameter of 3 mm, and uses the NUCLEODUR C18 Gravity-SB stationary phase with 5 µm particles. The EC-format precolumn is supplied in a pack of three pieces and is intended for main columns with 3, 4 or 4,6 mm internal diameter. It requires a Column Protection System guard-column holder (REF 718966) for installation. Offered by manufacturer Macherey-Nagel, this guard cartridge helps retain particulates and strongly retained matrix components before they reach the analytical bed, supporting stable reversed-phase separations and longer main-column lifetime. The compact EC 4\/3 geometry fits standard column-protection hardware used on many HPLC systems in routine analytical laboratories. Suitable for method development and day-to-day sample analysis where C18 Gravity-SB selectivity is already established on the primary column.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/hplc-columns\"\u003eHPLC columns\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/hplc-columns-and-accessories\"\u003eHPLC columns \u0026amp; accessories\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 3 pc(s)\u003c\/li\u003e\n\u003cli\u003eProduct type: HPLC guard column\u003c\/li\u003e\n\u003cli\u003eStationary phase: NUCLEODUR C18 Gravity-SB\u003c\/li\u003e\n\u003cli\u003eParticle size: 5 µm\u003c\/li\u003e\n\u003cli\u003eDimensions: length 4 mm, ID 3 mm\u003c\/li\u003e\n\u003cli\u003eEAN: 4046681056895\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Macherey-Nagel","offers":[{"title":"Default Title","offer_id":57998466646348,"sku":"76199230","price":156.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HPLC-NUCLEODUR-Vorsaeulen-3-1000Wx1000H_1aea8e13-172b-42d0-ae61-1f6396ec9930.jpg?v=1791407880","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/ec-43-nucleodur-c18-gravity-sb-5-m","provider":"Luminix Health","version":"1.0","type":"link"}
