General description
Silica gel with the indicator or orange gel frequently used
as a drying agent in laboratories is suitable for drying all gases and solids.
It is used in drying towers, desiccators, and absorption tubes. Due to its vast
surface area, silica gel orange provides excellent absorption capacity,
enabling longer storage conditions. When it absorbs moisture, it also turns
orange to colorless. (approx. 6 wt % load).
Application
Silica Gel with Orange gel indicator can be used for:
- Moisture
Management: Commonly found in desiccators, it protects
hygroscopic chemicals and solids from moisture, ensuring sensitive
materials stay intact during storage and experimentation.
- Chromatographic
Adsorption: Serves as a stationary phase in chromatography,
aiding in the effective separation and analysis of various chemical
compounds.
- Equipment
Protection: In laboratory settings, it absorbs excess humidity to
prevent corrosion and damage to sensitive equipment, extending the
lifespan of valuable instruments.
- Drying
Agent for Gases and Liquids: Utilized in drying towers and
absorption tubes, it efficiently removes moisture from gases and liquids,
improving the accuracy of analytical results.
