MERCK Ascarite Sodium Hydroxide-coated Silica 20-30 Mesh

MERCK Ascarite Sodium Hydroxide-coated Silica 20-30 Mesh

MERCK Ascarite Sodium Hydroxide-coated Silica 20–30 Mesh (223921) is a specialized chemical adsorbent engineered for the rapid and efficient removal of carbon dioxide and acid gases in analytical and microanalytical procedures. Ascarite represents a modern advancement over earlier adsorbents, consisting of a silica substrate uniformly coated with sodium hydroxide. This configuration allows for superior gas adsorption, making it ideal for laboratories focused on precision gas analysis.

Highly effective in laboratory environments requiring minimal contamination and maximum accuracy, Ascarite is a trusted choice among professionals in environmental testing, chemical analysis, and physiological studies.

Features

1. Self-indicating adsorption
   The material visually changes color (turns white) as sodium carbonate forms, enabling users to easily monitor the adsorbent’s saturation.

2. High adsorption efficiency
   Delivers rapid, quantitative CO₂ and acid gas removal, supporting precise measurements in analytical workflows.

3. Chemically stable and safe
   Non-asbestos formulation on an inert silica base ensures chemical stability and enhanced lab safety.

4. Broad compatibility
   Suitable for gas analysis, combustion analysis, and respiratory gas filtration in both manual and automated systems.

5. Long shelf life
   Packaged in air-tight containers to maintain reactivity and effectiveness over extended storage periods.

6. Trusted quality
   Manufactured by Merck, a globally recognized name in laboratory chemicals and materials, ensuring consistency and reliability.

Applications

1. Analytical gas filtration
   Ideal for trapping carbon dioxide in gas streams before entering detectors such as thermal conductivity detectors in gas chromatography.

2. Microanalytical procedures
   Widely used in combustion analysis and other small-scale experiments where accurate gas measurements are critical.

3. Physiological studies
   Employed in metabolic and respiratory research to eliminate CO₂ from exhaled gas samples.

4. Calibration systems
   Used in calibration gas setups to maintain purity and remove unwanted CO₂ contamination.

5. Industrial emissions testing
   Supports accurate monitoring of environmental air quality by removing CO₂ from sampling lines.

6. Educational laboratories
   Frequently used in teaching environments to demonstrate gas absorption techniques in a safe and observable manner.
