These are 30 mL high-form borosilicate glass crucibles with 30 mm fritted discs; Corning identifies 32940-30C as coarse porosity, 40 to 60 µm, and 32940-30M as medium porosity, 10 to 15 µm. Corning describes this series as suited for analytical work where precipitates are dried to constant weight at 110°C, with higher-temperature furnace use possible if thermal shock is avoided. Good general-purpose lab glassware lot for chemistry, QA\/QC, filtration, ash\/solids work, and replacement crucibles for vacuum filtration setups. Includes only the three crucibles shown; buyer should verify exact frit porosity mix from photos\/markings.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cp dir=\"ltr\" style=\"margin-top:0; margin-bottom:0;\"\u003e-BJ\u003c\/p\u003e","brand":"Lab Liquidators Store","offers":[{"title":"Default Title","offer_id":55360375947556,"sku":"SP111115427","price":49.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0748\/5289\/2964\/files\/10_9ea05126-c781-47cb-bd46-0d2ac1aa8928.jpg?v=1782487376","url":"https:\/\/store.labliquidators.com\/products\/lot-of-3-corning-pyrex-32940-30c-m-30mm-coarse-medium-fritted-gooch-crucibles","provider":"Lab Liquidators Store","version":"1.0","type":"link"}
