Description

Dräger's SODA LIME DRAGERSORB is a specialized product engineered for the efficient absorption of carbon dioxide (CO₂) and other acidic gases. It is primarily utilized in rebreathing systems, making it an essential component in anesthesia devices and closed-circuit breathing apparatus across medical and industrial applications.

Key Features

• Effective CO₂ Absorption: Ensures rapid and reliable removal of CO₂, enhancing the safety and functionality of rebreathing systems.
• Innovative Pellet Design: The hemispherical shape of the pellets reduces breathing resistance and extends usage periods. This design also minimizes dust formation, thanks to high abrasion resistance.
• Consistent Performance: Uniform filling of cartridges prevents channelling, ensuring reproducible CO₂ absorption. Some variants include a color indicator that transitions from white to violet, signaling when replacement is necessary.

Variants and Composition

SODA LIME DRAGERSORB is available in several versions, including Drägersorb 400 ind, 400 ind S, 400 S, and Drägersorb Free. These variants are tailored to specific needs, with differences in water content and the presence of a color indicator.

• Drägersorb Free Composition:
• Calcium hydroxide: 74–82%
• Calcium chloride: 3–5%
• Sodium hydroxide: 0.5–2%
• Water: 14–18%
• Ethyl violet (indicator): <0.1%

Notably, Drägersorb Free contains no potassium hydroxide, reducing the risk of byproduct formation with certain anesthetics.

Physical Properties

• Grain Size: 2–4 mm
• Bulk Density: 800 ± 100 g/L
• Water Content: 14–23% (variant dependent)
• Hardness: Typically 94.4%
• CO₂ Absorption Capacity: Up to 205 L CO₂ per kg

Safety and Handling

SODA LIME DRAGERSORB is classified as an irritant, necessitating precautions such as the use of dust masks, safety goggles, and gloves. It should be stored in tightly closed containers and kept away from water bodies due to its potential environmental impact.

Applications

This product is versatile, serving in medical settings for CO₂ absorption in anesthesia machines, and in industrial environments such as ventilation filters in wastewater plants and power plants. Its compatibility with CLIC disposable absorber cartridges facilitates easy replacement, enhancing convenience and efficiency.

Regulatory Compliance

SODA LIME DRAGERSORB is marked under CE 0123, adhering to the Medical Devices Directive 93/42 EEC. It is not classified as a dangerous good for transport, and it poses no flammability or hygroscopicity concerns, making it a reliable choice for various critical applications. With a shelf life of 2–5 years, it is available in packaging options like 15 kg pails and 18 kg canisters, ensuring long-term usability.
