Bicarbonate Indicator

Bicarbonate Indicator – CO₂ & pH Indicator Solution for Biology Labs | GLASSWORLD South Africa

Bicarbonate Indicator (hydrogencarbonate indicator, bicarbonate indicator solution) is a sensitive pH and CO₂ indicator solution widely used in biology, ecology, and environmental science education and research. Based on cresol red and thymol blue dyes in a sodium bicarbonate buffer, this indicator changes colour in response to dissolved CO₂ levels and pH shifts, making it an essential reagent for photosynthesis and respiration experiments. GLASSWORLD supplies bicarbonate indicator solution to schools, universities, and research laboratories across South Africa and sub-Saharan Africa.

Key Features

• Highly sensitive CO₂ indicator – Detects small changes in dissolved carbon dioxide concentration
• Clear colour change response – Purple (high pH/low CO₂) → Red (neutral) → Yellow (low pH/high CO₂)
• Ready-to-use solution – No preparation required; supplied as a stable working solution
• Ideal for photosynthesis and respiration experiments – Widely used in school and university biology practicals
• Available in various pack sizes – Suitable for classroom and research laboratory use

Applications

• Photosynthesis rate experiments (CO₂ uptake detection)
• Cellular respiration experiments (CO₂ production detection)
• Aquatic ecology and water CO₂ monitoring
• Environmental science and climate change education
• School and university biology laboratory practicals
• Research into plant physiology and gas exchange

Available in laboratory quantities. Supplied to schools, universities, and research laboratories across South Africa and sub-Saharan Africa. Request a quote for pricing, pack sizes, or bulk orders.
