About This Product
Because fused silica expands so little with heat, these vessels can be heated strongly and cooled quickly during ignition and incineration work, with the residue then weighed in gravimetric analysis. The Silica Crucible / Basin can be supplied on export terms to Croatia, Antigua and Barbuda, Democratic Republic of the Congo, Samoa and Zimbabwe.
