Capsules and crucibles are vessels for heating, drying, calcination, and ashing. Options include porcelain for general use, quartz for high thermal shock resistance, and silica for high-temperature work and low contamination. Available in low or tall form, with or without matching lids to minimise loss and contamination. Smooth, glazed exteriors support easy cleaning; unglazed interiors on some types aid evaporation. Suitable for gravimetric analysis, residue determination, and routine high-temperature procedures.
