Eduscope India is a leading Crucibles, Cylindrical Form, High Alumina
Quick Answer: the Crucibles, Cylindrical Form, High Alumina are unglazed, 99.7% pure alumina crucibles in a cylindrical profile, rated for continuous use up to 1750°C — the same high-alumina chemistry lab instruments supplier grade EduScope India offers in conical form, but shaped for applications where a straight-walled cylinder suits the furnace or sample geometry better than a taper.
Like other high-alumina ware, it's highly refractory, inert in hydrogen and carbonaceous atmospheres, and resistant to alkalies and fluxes that would attack lesser ceramics — properties that suit work with refractory metals such as molybdenum, platinum, rhodium, tungsten, tantalum and iridium. One handling detail matters more with alumina than with porcelain or quartz: temperature should not be ramped faster than 150°C per hour, so a crucible tongs India lab technician pulls it from a controlled-ramp furnace rather than plunging it in or out of heat suddenly.
