About Soda lime

Soda limeis a mixture of NaOH & CaO chemicals,usedin granular form in closed breathing environments, such as general anaesthesia, submarines, rebreathers and recompression chambers, to remove carbon dioxide from breathing gases to prevent CO2retention and carbon dioxide poisoning.

Superior CO2 Absorption Efficiency

Soda lime absorbs 180250 liters of CO2 per kilogram, making it an excellent choice for environments where carbon dioxide removal is critical. The products spherical or irregular granules maximize surface area, leading to fast and complete absorption, while low dusting ensures a cleaner and safer application in sensitive medical and industrial settings.

Safety and Quality Assured

Manufactured from high-grade materials, soda lime is non-toxic to humans under recommended use, making it safe for use in anesthesia machines and other breathing circuits. Its packaging in air-tight HDPE containers protects against moisture, preserving the products absorption capacity and extending its shelf life.

Versatile Applications

Soda lime effectively removes carbon dioxide in a wide range of applications including medical, laboratory, and industrial environments such as anesthesia systems, submarines, and rebreathing apparatus. Its adaptability and real-time operation enable seamless integration into diverse equipment demands, ensuring optimal performance and safety.

FAQs of Soda lime:

Q: How does soda lime absorb carbon dioxide in breathing circuits?

A: Soda lime functions through a chemical reaction between CO2 and the mixture of calcium hydroxide and sodium hydroxide, resulting in the conversion of CO2 into calcium carbonate and water. This process effectively removes CO2 from exhaled gases, making it ideal for medical and life-support applications.

Q: What are the key storage requirements for maintaining soda limes effectiveness?

A: To preserve soda limes absorption capacity, it should be stored in a cool, dry, well-ventilated area, kept tightly sealed in its air-tight HDPE drums, pouches, or bags. Exposure to moisture should be avoided, as it can degrade the product and reduce its shelf life.

Q: When should soda lime granules be replaced in an anesthesia machine?

A: Soda lime should be replaced when the color indicator (if present) changes from white to pink or violet, signaling exhaustion. Granules should also be replaced if they become hard, compact, or if the absorption capacity drops below recommended levels to maintain safe and effective CO2 removal.

Q: Where is soda lime primarily used?

A: Soda lime is mainly utilized in medical anesthesia machines, submarines, rebreathers, and various industrial gas purification systems in India and abroad. It is essential for environments that require controlled CO2 removal from breathing gas circuits or confined spaces.

Q: What benefits does soda lime offer for medical and industrial users?

A: Soda lime provides highly efficient CO2 absorption, real-time operation, low dusting, and a clear color indicator for exhaustion, ensuring both safety and ease of monitoring. Its non-toxic profile and silent performance make it suitable for sensitive applications.

Q: Can soda lime be used for portable applications and is it easy to handle?

A: Yes, soda lime is packaged in variable weights and dimension options, and designed for easy transport and use in portable situations. Its granule form further facilitates convenient handling and refilling.

Q: How long does soda lime last in storage, and what affects its shelf life?

A: When stored correctly in a cool, dry, sealed environment, soda lime maintains its quality and CO2 absorption efficiency for up to 2 years. Prolonged exposure to moisture or improper sealing can significantly reduce its effectiveness and usable life.
