Germinating Seed Respiration Demonstration Kit
Product Code : SCL-BLE-12403
The Germinating Seed Respiration Demonstration Kit (SKU SCL-BLE-12403) shows that germinating seeds take in oxygen as they respire. It consists of glass tubes with capillaries, a stand, potassium hydroxide (KOH) and two bottles of dye: the KOH absorbs the carbon dioxide given off, and a dye drop in the capillary moves as oxygen is used. This seed respiration kit suits school and college biology practicals, and JaincoLab manufactures it.
Specifications
The kit contains glass tubes with capillaries, a stand, potassium hydroxide (KOH) and two bottles of dye; the tube sizes, the amount of KOH and the dye colours are confirmed on the quotation.

Applications of the seed respiration kit
Germinating seeds are sealed in a tube with KOH to absorb carbon dioxide, and the movement of a coloured drop along the capillary shows the volume of oxygen taken up, which pupils can time and compare with dry or boiled seeds.
- Showing oxygen uptake by germinating seeds
- Measuring the rate of respiration
- Comparing germinating, dry and boiled seeds
- Understanding the role of KOH in absorbing carbon dioxide
- Respiration practicals in biology

Frequently asked questions
What does the kit show?
That germinating seeds use oxygen during respiration.
Why is KOH included?
Potassium hydroxide absorbs the carbon dioxide released, so the dye movement reflects oxygen uptake.
