Ground faces provide exact thickness and a plane-parallel surface, enabling reliable sealing and uniform filtration performance in laboratory and process glass assemblies. Porosity grade 4 is appropriate for finer filtration tasks where smaller pore structure and defined flow behaviour are needed. As a VitraPOR® filter plate from manufacturer ROBU - Stereon, it combines the chemical durability of borosilicate 3.3 with dimensional accuracy for frits, filter holders, and custom filtration setups. The single-piece unit is ready for use in analytical, preparative, and technical applications that call for a large biplane glass filter plate of porosity 4 with tightly toleranced thickness.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/sintered-glass-filter-plates-and-discs\"\u003eSintered glass filter plates \u0026amp; discs\u003c\/a\u003e, in \u003ca href=\"\/en-be\/collections\/filtration\"\u003eFiltration\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 pc\u003c\/li\u003e\n\u003cli\u003eProduct type: VitraPOR® biplane glass filter plate\u003c\/li\u003e\n\u003cli\u003eMaterial: Borosilicate glass 3.3\u003c\/li\u003e\n\u003cli\u003eDiameter: 210 mm\u003c\/li\u003e\n\u003cli\u003ePorosity: 4\u003c\/li\u003e\n\u003cli\u003eThickness: 11,5 mm ± 0,5 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ROBU - Stereon","offers":[{"title":"Default Title","offer_id":57933413908812,"sku":"62104","price":676.5,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/807-16xxx_b36f2736-6197-4a1e-b3d8-f4c6ca22f0e1.png?v=1783415271","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/filter-disc-bi-plane-210-mm-por-4-thickness-115-mm-05-mm","provider":"Luminix Health","version":"1.0","type":"link"}
