Germinating Seed Respiration Demonstration Kit
Product Code : SCL-BLE-11619
Germinating Seed Respiration Demonstration Kit (SKU SCL-BLE-11619) is a set for showing that germinating seeds respire, consisting of glass tubes with capillaries, a stand, potassium hydroxide (KOH) and two bottles of dye. It serves NCERT Class 10 and Class 11 biology practicals on respiration and B.Sc. plant physiology. This seed respiration set ships from Science Lab Supplies in Ambala, India, to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The seed respiration kit has four elements, each listed in its own row below. In short, glass tubes fitted with capillaries hold the seeds and show gas movement, the stand supports them upright, KOH absorbs carbon dioxide, and the two bottles of dye colour the liquid so its movement in the capillary is easy to follow.

Applications and Experiments for the Germinating Seed Respiration Kit
Germinating seeds take in oxygen and release carbon dioxide; when the KOH absorbs that carbon dioxide, the gas volume in the tube falls and the dyed liquid moves along the capillary. The kit is used for respiration practicals in Class 10 and Class 11 biology and in B.Sc. plant physiology.
- Class 10 biology: showing that seeds respire and use oxygen, with soaked seeds compared against dry or boiled ones.
- Class 11 biology: the NCERT practical demonstrating carbon dioxide release during respiration, with spare absorbent from Potassium Hydroxide Flakes.
- Revision and project work: linking the experiment to the growth stages shown on the Stages of Seed Germination Chart.
KOH is corrosive: handle it only under teacher supervision, with gloves and eye protection, and keep it away from skin and seeds. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Standard Scope of Supply
The kit is supplied with glass tubes with capillaries, a stand, a quantity of KOH and two bottles of dye. Seeds are not included; the laboratory soaks and germinates its own seeds a few days before the practical, and extra KOH can be quoted separately.
Packing, MOQ and Lead Time
You can ask for a price on one kit or on a set for each practical group. The quotation gives the price, packing method and delivery time for the number requested, and extra KOH, dyes or related respiration apparatus can be added for a single delivery.
Under its Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman.

Frequently Asked Questions
What does the KOH do in this experiment?
Potassium hydroxide absorbs the carbon dioxide given off by the germinating seeds. As the gas is removed, pressure inside the tube drops and the dyed liquid moves along the capillary, showing that oxygen is being used.
Are seeds supplied with the kit?
No. Seeds such as gram, pea or wheat are soaked and germinated by the laboratory before the lesson. The kit supplies the glass tubes with capillaries, stand, KOH and two bottles of dye.
Who supplies the Germinating Seed Respiration Demonstration Kit?
Science Lab Supplies, based in Ambala, India, supplies this kit to schools, colleges and distributors, and can include extra KOH, dyes and respiration apparatus in the same shipment.
