Soda Lime Self Indicating

What is Soda Lime Self-Indicating? Soda Lime Self-Indicating is a mixture of sodium hydroxide (NaOH) and calcium hydroxide (Ca(OH)₂) that is primarily used to absorb carbon dioxide (CO₂) in medical and laboratory settings. The self-indicating version contains a pH indicator that changes colour when the soda lime becomes saturated with CO₂, providing a visual cue that it is time to replace the material.

Consistent Quality: We use only carefully sourced Soda Lime Self-Indicating, ensuring consistent performance across various applications.

Shipped from Manchester, UK Facility: Sourced and packaged using non-toxic, chemical-resistant containers, ensuring reliable quality for our customers.

Frequent Uses

Anaesthesia Machines
Widely used in medical anaesthesia machines to absorb CO₂ from exhaled air, preventing CO₂ buildup in patients during surgeries and ensuring safe anaesthetic conditions.

Respiratory Equipment
In ventilators and other respiratory devices, it removes CO₂ from the air supplied to patients, maintaining optimal oxygen levels and preventing the harmful effects of CO₂ accumulation.

Laboratory CO₂ Removal
Used in laboratories to absorb CO₂ from air or gas streams during various experiments and chemical reactions. The colour change feature helps monitor when the absorbent is saturated and requires replacement.

Carbon Dioxide Scrubbing in Closed Systems
In confined systems, such as submarines, spacecraft, or sealed breathing apparatus, it helps maintain breathable air by absorbing CO₂. The self-indicating feature allows users to track the absorbent's condition, ensuring the CO₂ scrubbers continue to function properly.

Environmental Control Systems
Useful in systems that require precise control of air quality, such as in greenhouses or industrial applications. By absorbing CO₂, it helps to maintain safe and breathable environments in these controlled spaces.

Breathing Systems in Animals and Research
In research involving animals or veterinary applications, it is used to manage CO₂ levels in inhaled air. The visual indicator helps ensure that the soda lime is replaced when necessary, contributing to safer respiratory conditions.

Safety Applications
Plays a crucial role in controlling CO₂ levels in various environments, especially in confined spaces or during long-term use. The self-indicating feature is particularly useful in alerting users when the absorbent is no longer effective, preventing harmful CO₂ buildup and ensuring a safe atmosphere.

Scuba Diving
Used in scuba rebreathers to remove carbon dioxide (CO₂) from exhaled air, allowing for the recycling of oxygen. As the diver exhales, the CO₂ reacts with the soda lime, forming calcium carbonate and water, thus cleaning the air. This process helps maintain a safe breathing environment by preventing the diver from re-breathing CO₂, and the soda lime must be replaced after it becomes saturated.
