{"product_id":"uhplc-guard-columns-nucleodur-38pk-38pk","title":"UHPLC Guard Columns NUCLEODUR®, C8 Gravity, 1.8µm, 4x3mm, 3 unit(s)","description":"\u003cp\u003eUHPLC Guard Columns NUCLEODUR® C8 Gravity (1,8 µm, 4 × 3 mm) are protective pre-columns for ultra-high-performance liquid chromatography systems. Positioned before the analytical column, they capture particulates and strongly retained sample constituents, supporting stable chromatographic performance and longer analytical-column lifetime. The C8 Gravity stationary phase supplies reversed-phase octyl selectivity appropriate for many moderately hydrophobic analytes under UHPLC conditions. The pack comprises 3 pc(s) and has a stated weight of 0,023 kg, facilitating organised stock rotation in high-throughput laboratories. NUCLEODUR® guard columns from manufacturer MACHEREY-NAGEL are configured for use with matching UHPLC column hardware. A particle size of 1,8 µm is consistent with contemporary sub-2 µm UHPLC packings and the associated pressure and flow ranges. The 4 × 3 mm geometry balances protective bed volume with limited extra-column contribution. These units are intended for professional laboratory chromatography, including method development, routine analysis, and quality-control workflows that benefit from reliable inlet protection of the primary separation column.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/hplc-guard-columns\"\u003eHPLC guard columns\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/hplc-columns-and-accessories\"\u003eHPLC columns \u0026amp; accessories\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 3 pc(s)\u003c\/li\u003e\n\u003cli\u003eProduct type: UHPLC guard columns\u003c\/li\u003e\n\u003cli\u003eBrand: NUCLEODUR®\u003c\/li\u003e\n\u003cli\u003eStationary phase: C8 Gravity\u003c\/li\u003e\n\u003cli\u003eParticle size: 1,8 µm\u003c\/li\u003e\n\u003cli\u003eColumn dimensions: 4 × 3 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Macherey-Nagel","offers":[{"title":"3 pc(s) \/ 1 piece","offer_id":56151563600204,"sku":"38PK.1","price":167.7,"currency_code":"EUR","in_stock":true},{"title":"3 pc(s) \/ 6+ pieces","offer_id":56151563632972,"sku":"38PK.1","price":159.32,"currency_code":"EUR","in_stock":true},{"title":"3 pc(s) \/ 24+ pieces","offer_id":56151563665740,"sku":"38PK.1","price":150.93,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HPLC-NUCLEODUR-Vorsaeulen-3-1000Wx1000H_612cb8c3-d605-4b40-8384-720b4d227b47.jpg?v=1766437268","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/uhplc-guard-columns-nucleodur-38pk-38pk","provider":"Luminix Health","version":"1.0","type":"link"}
