Crucibles
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.
