Crucibles
Sigma Aldrich Fine Chemicals Biosciences Platinum crucible lid fits1EA
Platinum labware has excellent resistance to acids such as acetic hydrochloric hydrofluoric hydroiodic nitric selenic and sulfuric and to oxidation at high temperatures. Crucible lids of platinum can be cleaned by boiling in a suitable solvent.For the removal of substances which have alloyed with the surface scour with alumina powder.
Chemglass Life Sciences Crucible, 10mL, Low Form, Porcelain
Crucible, 10mL, Low Form, Porcelain. Low form crucible complete with lid, glazed both inside and outside with the exception of the outside lower bottom and rim.Due to its inherent properties, Porcelain Labware is widely used in the chemistry laboratory. It has excellent resistance to all reagents except hydrofluoric acid, and is highly resistant to thermal shock while having a very low coefficient of expansion.The average coefficient of expansion from 20° to 200°C is 3.56 x 10-5 gradually increasing to 4.69 x 10-5 at 1000°C. To prevent thermal stress cracks on porcelain ware do not exceed a heating/cooling rate of 200°C per hour.To prolong the life of porcelain products:• Follow gradual heating/cooling rates• Use an oven or hot plate and an intermediate step when quicker heating/cooling rates are required• Avoid contact of heated ware with a cold surface• Carefully inspect labware prior to each use and do not use any product that appears defective.

Sigma Aldrich Fine Chemicals Biosciences PyrexR Gooch crucible high
Particularly adapted to analytical work where precipitates are dried to constant weight at 110C. Also suitable for higher temperatures in which case is advisable to heat in an electric furnace.Crucibles should not be subjected to sudden temperature changes.In order to avoid strain they should not be removed from the furnace until the temperature has dropped to 250C.

Waters TA Instruments Aluminum Sample Pans For SFI Samples are DSC solid fat index pans designed specifically for evaluating edible fats and oils. The pans feature a recessed rim around the bottom to prevent wicking due to surface tension and are compatible with standard DSC lids.
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.
