Crucibles contain solutions to be dried for constant weight using extreme temperatures then to be ashed for minimizing weight. Often featuring a perforated bottom, the vessels serve as a filter depositing precipitates. The high grade containers are offered in both high and low form styles with or without lids. Stable crucibles are resistant to even harsh substances. Available in a variety of capacities, manufacturing, and glazing options to easily modify based on procedure and sample. VWR offers various kinds of crucible designs including porcelain, nickel and graphic crucibles. Ceramic crucibles are temperature resistant and can withstand temperatures of the range of 1400 Celsius.
