Product Description:
Glass Wool, Part Number 90331, is a specialized high-temperature filtration and insulation material used in combustion and elemental analyzers. It serves as both a gas purification barrier and a thermal insulator, making it essential for precise, clean, and stable combustion conditions during elemental analysis.

In ONH, CHS, and thermal analyzers, glass wool is typically used to support reagents, trap particulate matter, and maintain temperature uniformity within the combustion or reduction tube. Its high thermal resistance and chemical inertness ensure that it does not interfere with analytical results while helping to protect both reagents and instrument components from contamination.

• High-Temperature Resistant – Withstands extreme combustion conditions
• Excellent Filtration – Traps ash, dust, and particles that can skew results
• Chemically Inert – Will not react with sample gases or reagents
• Supports Reagent Beds – Prevents reagent migration and promotes even gas flow
• Extends Analyzer Life – Protects sensitive components and improves result consistency

Function in Combustion Analysis:
Glass wool acts as a physical barrier within combustion systems, preventing particulate matter from reaching the detectors while allowing gases to pass freely. It is commonly used to secure catalyst and absorbent materials, such as copper oxide or soda lime, ensuring consistent performance and gas flow. Additionally, glass wool can help buffer sudden temperature changes within the system, stabilizing combustion conditions for more reliable analysis.

Ideal For Use In:

• ONH and OH Elemental Analyzers – Supports reagent placement and prevents contamination
• CHS and Carbon-Sulfur Analyzers – Filters out sample debris and extends reagent life
• TGA and Thermal Systems – Provides insulation and supports temperature stability
• Combustion and Flow-Through Modules – Acts as a non-reactive support and barrier material

Applications:
Used across metallurgical labs, environmental analysis, ceramics, polymers, and materials testing, glass wool ensures clean combustion, accurate gas flow, and prolonged system integrity.
