The Free Swelling Index test is a rapid, small-scale, empirical method for measuring the free-swelling properties of coal. Results of the test may be used as an indication of the coal's coking characteristics, and have also been used as an index of the extent to which a coal has been oxidized or weathered. The test creates a coke button for comparison to a standardized size scale.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eRapid, easy, small-scale, and empirical method for measuring the free-swelling properties of coal.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eSupplied with\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eFurnace and lid.\u003c\/li\u003e \u003cli\u003eTripod and crucible holder assembly.\u003c\/li\u003e \u003cli\u003eTemperature control unit with automatic timer and alarm.\u003c\/li\u003e \u003cli\u003eCrucibles and cover.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eAdditional Models \u003c\/strong\u003e\u003c\/p\u003e \u003ctable border=\"0\" width=\"400\" cellspacing=\"0\" cellpadding=\"0\" align=\"center\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd align=\"center\" width=\"50%\"\u003e\u003cstrong class=\"ctrhdrtext\"\u003eCatalog Number\u003c\/strong\u003e\u003c\/td\u003e \u003ctd align=\"center\"\u003e\u003cstrong class=\"ctrhdrtext\"\u003eVolts\/Hertz\u003c\/strong\u003e\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003ctable class=\"catlinks\" border=\"1\" width=\"400\" cellspacing=\"0\" cellpadding=\"0\" align=\"center\"\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd class=\"ctrhdrtext\" align=\"center\" bgcolor=\"#e5ecf9\" width=\"50%\"\u003e\u003cspan\u003eFRS-41000A1\u003c\/span\u003e\u003c\/td\u003e \u003ctd class=\"ctrbodytext\" align=\"center\"\u003e115V\/60Hz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd align=\"center\" bgcolor=\"#e5ecf9\"\u003e\u003cspan\u003eFRS-41000A2\u003c\/span\u003e\u003c\/td\u003e \u003ctd class=\"ctrbodytext\" align=\"center\"\u003e115V\/50Hz\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd align=\"center\" bgcolor=\"#e5ecf9\"\u003e\u003cspan\u003eFRS-41000A3\u003c\/span\u003e\u003c\/td\u003e \u003ctd class=\"ctrbodytext\" align=\"center\"\u003e230V\/60Hz\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e","brand":"Preiser Scientific Inc","offers":[{"title":"EA (1)","offer_id":51111497531707,"sku":"FRS-41000A4-EA","price":6785.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0921\/2041\/6571\/files\/FRS-41000A4.png?v=1784718319","url":"https:\/\/preiser.com\/products\/preiser-free-swelling-index-fsi-furnace-230-v-50-hz","provider":"Preiser Scientific","version":"1.0","type":"link"}
