Moisture Crucible C/W Lid 20ml

Moisture Crucible C/W Lid 20ml

A Moisture Crucible C/W Lid 20ml (complete with lid) is a small laboratory vessel—typically made of porcelain or high-purity alumina ceramic—used to hold, heat, and process small-volume samples at high temperatures. 

Main Uses in the Laboratory

• Moisture and Water Content Determination: Used to dry samples and measure the loss of moisture or water content when heated in an oven or furnace.
• Ash Content Determination: Used to burn off organic material in substances like coal, oil, wood, or food samples until only unburnable inorganic ash remains.
• Gravimetric Analysis & Ignition: Used to ignite, calcine, or heat chemical precipitates and mineral compounds to a constant mass.
• Melting and Evaporation: Holds small volumes of powders, salts, or liquids during high-temperature heating, while the matching lid helps prevent spattering, sample loss, or excessive evaporation

Key Features

• Capacity: 20 mL, ideal for micro-to-small sample sizing.
• Lid Function: Reduces sample spitting, controls gas venting around the edges, and limits atmospheric contamination or moisture reabsorption during cooling.
• Material Tolerance: Withstands high laboratory temperatures (typically ranging past 1050°C–1150°C for porcelain variants and higher for alumina).
