Wilmott’s Bubbler

Product Code : SCL-LG-11976

Wilmott’s Bubbler (SKU SCL-LG-11976) is a plant-physiology apparatus that makes photosynthesis visible: an aquatic plant releases gas as bubbles, and students count them over a fixed time to compare the rate under different conditions. It suits photosynthesis and limiting-factor practicals in senior school and college biology. Enquiries for the bubbler are answered by Science Lab Supplies in Ambala, India, for schools, colleges, tender contractors and distributors.

Specifications

Wilmott’s Bubbler is summarised fact by fact in the table that follows. In short, gas evolved by a submerged aquatic plant rises as bubbles, and the bubble count per interval serves as a comparative indicator of photosynthetic activity; capacity, material, dimensions and the exact vessel and tube layout are confirmed on the quotation.

Applications and Experiments for Wilmott’s Bubbler

The bubbler lets a class test how one factor at a time changes the rate of photosynthesis. Students keep everything else constant, vary light intensity or another factor, count bubbles over equal intervals and plot the results, which leads naturally to the idea of limiting factors.

• NCERT Class 10 biology (life processes): showing that green plants release oxygen in light.
• NCERT Class 11 biology (photosynthesis in higher plants): Blackman's law of limiting factors.
• B.Sc. botany plant-physiology practicals: effect of light intensity or distance on bubble rate, with an adjustable Miniature Lamps on Clamp Stands unit as the light source and water temperature checked on Laboratory Thermometers.
• Data-handling work: timing equal counting intervals with a Digital Stopwatch, then tabulating bubble counts and drawing rate graphs.

Keep lamps and cables away from water, and give the plant time to settle before counting.

Standard Scope of Supply

The supply is one Wilmott’s Bubbler apparatus, with the exact vessel and tube configuration confirmed on the quotation. The aquatic plant is obtained separately; water, reagents, a timer, a thermometer and a light source can be sourced locally or added to the same quotation.

Packing, MOQ and Lead Time

Request one bubbler for teacher demonstrations or a set for student groups, and the quotation will show packing, delivery time and price for that number. Potometers, respirometers and fermentation tubes can join the same quotation for a complete plant-physiology bench from one laboratory glassware supplier in India.

Science Lab Supplies, a registered exporter with an Importer-Exporter Code, can ship to buyers in Oman, the Philippines, Nepal, Bangladesh, Zambia and Rwanda. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Ask about group quantities through the contact page, assemble a plant-physiology list in the enquiry cart, or use the lab tender page when your school buys by tender.

Frequently Asked Questions

What do the bubbles in Wilmott’s Bubbler show?
They are gas released by the aquatic plant during photosynthesis, treated as oxygen in the standard experiment. More bubbles per minute indicate faster photosynthesis under those conditions.

Does bubble counting give an exact rate?
No. Bubbles vary in size, so the count is a comparative indicator of photosynthetic activity. An experiment that needs the absolute gas volume requires suitable calibrated collection equipment instead.

Who supplies Wilmott’s Bubbler?
From Ambala in India, Science Lab Supplies prepares the quotation for this bubbler, confirms its configuration and packing, and arranges dispatch for schools, colleges and tender contractors.

Is an aquatic plant included?
No. The specimen is obtained separately: use a suitable fresh aquatic plant available locally, chosen according to your teaching protocol, and let it settle before counting begins.
