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. Biology teachers use it for photosynthesis and limiting-factor practicals in senior school and college. Science Lab Supplies offers the apparatus from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.

Specifications

The apparatus works on a simple observation principle: gas evolved by a submerged aquatic plant rises as bubbles, and the bubble count per interval serves as a comparative indicator of photosynthetic activity. The listing does not give capacity, material, dimensions or the exact vessel and tube layout, so these 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.
• Data-handling work: 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 listing covers one Wilmott’s Bubbler apparatus, with the exact vessel and tube configuration confirmed on the quotation. Aquatic plants, water, reagents, a timer, a thermometer and a light source are not confirmed as included and can be sourced locally or quoted separately.

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). Price requests can be sent through the contact page or the enquiry cart; for tenders, visit the lab tender page.

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. Measuring absolute gas volume needs calibrated collection equipment.

Who supplies Wilmott’s Bubbler?
Science Lab Supplies supplies it, dispatching from Ambala, India and confirming the configuration and packing on each quotation for schools, colleges and tender contractors.

Is an aquatic plant included?
No plant is confirmed as included. Use a suitable fresh aquatic plant available locally, chosen according to your teaching protocol.

Related Plant Physiology Apparatus

Photosynthesis is usually taught alongside respiration, fermentation and transpiration. These four glass apparatus from the same range cover those practicals, so a biology department can equip its plant-physiology bench on one quotation.

• Kuhne’s Fermentation Tube — carbon dioxide from yeast fermentation.
• Respirometer with Stand — respiration in germinating seeds.
• Student Potometer ‘H’ type — water uptake by a leafy shoot.
• Ganong’s Potometer — transpiration rate with a reservoir reset.
