Cellular Respiration
Product Code : LSK-BL-10177
Cellular Respiration (SKU LSK-BL-10177) is a class kit in which students build microrespirometers to observe respiration in germinating peas and describe how temperature affects its rate. It also shows how the gas laws explain the movement of fluid in the microrespirometer. The kit suits Class 11 biology, B.Sc. botany and zoology practicals for 10 groups. Science Lab Supplies sends it out from Ambala, India, on quotation to schools, colleges, tender contractors and distributors.

Applications and Experiments for the Cellular Respiration Kit
Students use the kit to measure oxygen uptake by germinating peas. Potassium hydroxide absorbs the carbon dioxide released, so the gas volume in each vial falls and a marker drop moves along the pipet. Glass-bead controls and water baths at different temperatures let groups compare respiration rates from their own readings.
- Class 11 biology: respiration in plants and the effect of temperature on metabolic rate.
- Water baths at two or more temperatures, each checked with a Glass Thermometer, for a temperature-versus-rate graph.
- Germinating versus non-germinating seed comparisons, supported by a Stages of Seed Germination Chart.
- Physics links: pressure, volume and temperature of a trapped gas, explained through the gas laws.
Potassium hydroxide solution is corrosive to skin and eyes. Students should wear goggles and gloves, and a teacher should dispense it onto the cotton.
Standard Scope of Supply
Each kit contains instructions, 1 ml pipets, glass beads, peas, potassium hydroxide solution, cork stoppers, absorbent and non-absorbent cotton, plastic vials and parafilm for 10 groups. Thermometers, long trays, silicone glue, a cork borer, tape and timers are not included. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Packing, MOQ and Lead Time
Pricing is available for a single kit or for a quantity matched to several biology sections. Every quotation from Science Lab Supplies gives the packing, the delivery time and the price for that order, and thermometers or timers can be quoted next to the kits.
Holding an Importer-Exporter Code, Science Lab Supplies is able to ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia. Reach the team through the contact page, save the kit to the enquiry cart for a combined quote, or use the lab tender page for bid documents.
Frequently Asked Questions
What does the Cellular Respiration kit measure?
It measures the rate of cell respiration in germinating peas through oxygen uptake in a microrespirometer, and shows how that rate changes when the temperature of the surrounding water is changed.
Why are glass beads included?
Glass beads fill a control vial to the same volume as the peas without respiring. Any movement in the control shows changes caused by temperature or pressure alone, which students subtract from the pea readings.
Is the potassium hydroxide hazardous?
Yes. Potassium hydroxide solution is corrosive and can burn skin and eyes. Use it under teacher supervision, wear goggles and gloves, and rinse any splash with plenty of water at once.
Who is the supplier?
Science Lab Supplies prepares quotations and dispatch for this kit from Ambala, India, for single schools as well as distributors and tender contractors.
