CEM Corporation QUARTZ CRUCIBLE 50/CS
CEM's unique, patented quartz fiber crucibles reduce ashing times by as much as 97% and cool in seconds. The quartz fiber material allows oxygen to circulate around the sample speeding combustion even with our unique crucible caps in place. These unbreakable crucibles withstand temperatures up to 1,000 deg.C and do not need desiccation. Quartz fiber crucible caps can be used with our 50- or 100-ml crucibles. Try them out next time you have to ash a sample that needs to be contained. Ideal for low ash samples and samples with high organic content, they reduce the chance for sample contamination and improve accuracy on ROI and LOI determinations.
XRF Scientific Americas Inc. PLATINUM CRUCIBLE STANDARD SHAPE 20ML FROM XRF SCIENTIFIC AMERICAS
33X35mm with a 20 ml capacity. Lids sold separately. These 99.95% pure platinum crucibles are available in tall and wide forms, and used for Fusions, Digestion, Ash testing, Loss on Ignition (LOI). Due to their high temperature strenght, ductility, corrosion and oxidation, excellent resistance to chemical attacks by acids and fusion mixtures resistance; these platinum crucibles are critical when high temperatures & resistance to chemical attacks are required.
Chemglass Life Sciences Crucible, 500mL, Low Form, Porcelain
Crucible, 500mL, 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.
