Desiccators-Porcelain Plate 300mm

Desiccators With Lid Porcelain Plate 300mm.

300mm desiccators with lids and porcelain plates are large-capacity laboratory vessels used to dry, store, and protect moisture-sensitive materials (such as anhydrous reagents, crystals, or metallurgical samples) from humidity. The porcelain plate allows air circulation while supporting items, making them essential for maintaining constant sample weight, degassing, or vacuum applications.

Key Uses and Applications
Moisture Removal & Storage: Used for drying moist products and storing hygroscopic materials that deliquesce (melt/deteriorate) upon exposure to air.
Maintaining Constant Weight: Ideal for cooling crucibles or materials after heating in an oven to prevent them from re-absorbing moisture before weighing.
Vacuum Desiccation: When equipped with a stopcock they are used to remove air bubbles from gels, creams, or to accelerate the drying process.
Large Sample Capacity: The 300mm size provides a substantial, stable platform for accommodating larger items or multiple smaller samples.
Industry Application: Widely used in the petrochemical, pharmaceutical, steel/metallurgy, and scientific research industries for storing delicate equipment like microscope lenses and precision metal components.

Key Components & Setup
Porcelain Plate: Positioned on an internal ledge, this perforated plate allows a desiccant (like silica gel or calcium chloride) to be placed underneath while supporting the sample above.
Lid & Seal: The lid, often with a plastic or glass knob, ensures a tight seal, typically with Vaseline or vacuum grease applied to the ground glass flange to isolate the interior from atmospheric humidity.
Material: Usually constructed from Borosilicate 3.3 glass or high-quality neutral glass for thermal and chemical resistance.
