Lab Crucibles

Spectrum Chemical carries a wide selection of lab crucibles in a variety of materials. Choose from crucibles constructed of pure heavy sheet nickel which is suitable for fusions and highly resistant to dilute alkalies; or porcelain crucibles which are glazed inside and out, except for outside bottom surface. We also carry porous bottom crucibles with porous disc permanently formed into walls which allow stable porosity and rate of flow.
