The surfaces are ground to provide exact thickness together with a plane-parallel finish. This precision filter plate from manufacturer ROBU - Stereon is supplied in packs of 5 pc(s). The biplanar geometry presents two flat parallel faces that support accurate seating and uniform contact in filtration assemblies. Porosity grade 3 defines the sintered-glass pore structure that governs flow and retention behaviour. The stated thickness tolerance of ± 0,2 mm ensures dimensional consistency from plate to plate. Borosilicate 3.3 glass contributes chemical durability and thermal stability typical of laboratory sintered media. Ground faces guarantee the planarity and thickness accuracy described in the product data. The 70 mm diameter matches common filter-holder formats used in analytical and preparative work. Each plate maintains the VitraPOR® standard for controlled porosity and mechanical integrity, enabling reliable solid-liquid separation under routine laboratory conditions.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/sintered-glass-filter-plates-and-discs\"\u003eSintered glass filter plates \u0026amp; discs\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/filtration\"\u003eFiltration\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 5 pc(s)\u003c\/li\u003e\n\u003cli\u003eMaterial: Borosilicate 3.3 glass\u003c\/li\u003e\n\u003cli\u003eDiameter: 70 mm\u003c\/li\u003e\n\u003cli\u003ePorosity: 3\u003c\/li\u003e\n\u003cli\u003eThickness: 4,5 mm ± 0,2 mm\u003c\/li\u003e\n\u003cli\u003eSurface: Ground, plane-parallel\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBU - Stereon","offers":[{"title":"Default Title","offer_id":57934203912524,"sku":"16703","price":158.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-16703.png?v=1783731091","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/filter-disc-bi-plane-70-mm-por-3-thickness-45-mm-02-mm","provider":"Luminix Health","version":"1.0","type":"link"}
