Sodalime with indicator 500gm

Original price was: KSh1,500.00.Current price is: KSh1,200.00.

Sodalime with an indicator is a substance often used in medical and laboratory settings, primarily for the absorption of carbon dioxide (COā‚‚) and certain other acidic gases. The indicator in sodalime serves a crucial function by visually signaling when the sodalime has been exhausted and can no longer effectively absorb COā‚‚. Here’s a detailed look at its components, functionality, and use:

Components of Sodalime

  1. Sodium Hydroxide (NaOH) and Potassium Hydroxide (KOH): These strong bases are the active components that react with COā‚‚ to form carbonates and water.
  2. Calcium Hydroxide (Ca(OH)ā‚‚): This provides a medium in which the reaction takes place and also participates in the COā‚‚ absorption process.
  3. Water (Hā‚‚O): Necessary for the chemical reaction.
  4. Indicator Dye: Changes color based on the pH level, signaling when the sodalime is no longer effective.

Chemical Reaction

Uses ofĀ  Sodalime with indicator

Gas Absorption in Experiments

Sodalime is frequently used to remove COā‚‚ from gas streams in laboratory experiments. This is important in studies where COā‚‚ could interfere with the results or where its removal is necessary to simulate certain environmental conditions.

2. Respiratory Metabolism Studies

In studies involving animal or human respiratory metabolism, sodalime can be used to absorb the COā‚‚ exhaled by subjects. This allows researchers to measure oxygen consumption and other metabolic parameters accurately.

3. Chemical Synthesis and Reactions

Certain chemical reactions and syntheses are sensitive to the presence of COā‚‚. Sodalime is used to maintain a COā‚‚-free environment, ensuring that these reactions proceed correctly without interference from COā‚‚.

4. Incubators for Cell Culture

In cell culture incubators, maintaining the correct gas composition is crucial for cell growth and development. Sodalime is used to control COā‚‚ levels within these incubators, ensuring an optimal environment for cell cultures.

5. Anaerobic Chambers

Anaerobic chambers are used for growing and handling anaerobic microorganisms, which thrive in environments devoid of oxygen and COā‚‚. Sodalime helps to scrub COā‚‚ from the chamber, creating a suitable atmosphere for these microorganisms.

6. Respiratory Equipment Calibration

Calibration of respiratory equipment, such as spirometers and gas analyzers, often requires precise control of gas concentrations. Sodalime can be used to absorb COā‚‚ during the calibration process to ensure accurate measurements.

7. Environmental Simulation Chambers

In studies simulating various environmental conditions, such as climate change experiments, sodalime can be used to control and maintain specific COā‚‚ levels, allowing researchers to study the effects of different COā‚‚ concentrations on plants, animals, and materials.

8. Respiratory Physiology Research

In respiratory physiology research, sodalime is used to remove COā‚‚ from exhaled air, enabling the study of lung function and gas exchange processes in isolation from the effects of COā‚‚.
