Composition: Pt Form: Crucible Material: Platinum CAS Number: 7440-06-4 Commodity: Precious Metals Outside Diameter: 40mm Inside Diameter: 30mm Height: 30mm
Platinum Flat Bottomed Crucible with Handle and Pouring Lip (99.99% purity) is designed for safe manual handling of the heated crucible in workflows where the operator must transfer, tilt, or position the vessel while it is still at or near working temperature. Available at OD 40 mm with a 30 mm height, the integral handle allows the crucible to be manipulated directly from the furnace without tongs in applications where tong contact risks deformation or melt disturbance, while the pouring lip enables controlled, directed transfer of fused or molten material. Manufactured from 99.99% pure platinum, it is suited to XRF fusion sample preparation and small-volume melt work in laboratory settings where workflow efficiency and operator safety during hot handling are both design priorities. Goodfellow supplies this crucible with full material certification suitable for analytical and quality control laboratory environments.
