Photosynthesis Kit
Product Code : LSK-BL-10176
Photosynthesis Kit (SKU LSK-BL-10176) is a class set for measuring the rate of photosynthesis indirectly with the floating leaf disk assay and testing which variables change that rate. It is written for Class 9–12 biology and first-year B.Sc. botany practicals and covers 10 lab groups. Science Lab Supplies quotes and dispatches the kit from Ambala, India, for schools, colleges, tender contractors and distributors alike.

Applications and Experiments for the Photosynthesis Kit
The kit is used to show that leaves produce oxygen in light and to compare how fast this happens under different conditions. Students punch leaf disks, draw the air out of them with a syringe in bicarbonate solution, then time how long the disks take to float as oxygen builds up inside them.
- Class 10 and Class 11 biology: photosynthesis and the need for light and carbon dioxide, a core NCERT topic.
- Investigations of light intensity, light colour or bicarbonate concentration, with each group working in a Chemical Glasses (Beaker) 250ml.
- Graphing practice: plotting the number of floating disks against time, read from a Mechanical Timer 60min or a stopwatch.
- B.Sc. botany: an introduction to measuring photosynthetic rate before gas-collection methods.
Standard Scope of Supply
The kit contains instructions, sodium bicarbonate, liquid soap, plastic syringes, transfer pipets, plastic cups and metric rulers for 10 lab groups. Leaves, a light source, a timer, a hole punch and beakers are not included and can be prepared by the school. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.

Frequently Asked Questions
What is the floating leaf disk assay?
Leaf disks are soaked in bicarbonate solution and the air in them is removed with a syringe, so they sink. In light, photosynthesis releases oxygen into the disks and they rise; the time taken shows the rate indirectly.
How long does the practical take?
The full experiment takes about 1.75 hours, which fits two lab periods. The first period can cover disk preparation and the light set-up, and the second can cover timing, results and graphs.
What does the school need to add?
Fresh leaves, a light source, a timer, a hand-held hole punch and beakers. Everything else needed for 10 groups, including syringes, pipets, cups, rulers, bicarbonate and soap, comes in the kit.
Who supplies the kit, and from where?
Orders for this kit are handled from Ambala, India, by Science Lab Supplies, which can price single kits or bulk lots for schools, colleges and contractors.
