Crucibles
Sigma Aldrich Fine Chemicals Biosciences CoorsTM high-alumina cruci1EA
Made of 99.8% pure recrystallized aluminum oxide for high resistance to chemical attack. for use in reducing and oxidizing atmospheres and refractory metals (such as molybdenum platinum rhodium tungsten tantalum and iridium). O.D. dimension tolerance is /-5%. Max. use temp. (no load) 1 750 C.
Sigma Aldrich Fine Chemicals Biosciences CoorsTM porcelain crucible
Glazed inside and out except for outside bottom surface and rim.Max. use temp. 1150C limit of use evacuated 1300CCrucibles are not porous so there should not be any change in weight after firingOrder covers separately.

Sigma Aldrich Fine Chemicals Biosciences Platinum crucible with rei1EA
Platinum labware has excellent resistance to acids such as acetic hydrochloric hydrofluoric hydroiodic nitric selenic and sulfuric and to oxidation at high temperatures. These platinum crucibles can be cleaned by boiling in a suitable solvent for the removal of substances which have alloyed with the surface scour with alumina powder. Having a reinforced rim means that the rim of the crucible is thicker than the walls to make it stronger this is where the crucible can be gripped if tongs are used during the handling process.
