Wilmott’s Bubbler

Product Code : SCL-LG-11976

The Wilmott’s Bubbler apparatus is a plant physiology device used for demonstrating and comparing oxygen-bubble evolution by an aquatic plant during photosynthesis. It is intended for biology students, teachers and laboratory demonstrators who need a visible method for studying how light or other controlled variables influence photosynthetic activity.

Product Description

Wilmott’s Bubbler provides an observable way to investigate the rate of photosynthesis. Gas released by an aquatic plant appears as bubbles, which can be counted over a fixed period. The bubble rate acts as a comparative indicator of photosynthetic activity under controlled experimental conditions.

The apparatus supports lessons on oxygen evolution, limiting factors and experimental variables. Its capacity, material, dimensions and exact glassware configuration were not supplied and must be confirmed before publication or procurement. Related teaching apparatus can be found in the biology laboratory equipment range.

Key Features

• Visible photosynthesis demonstration: Makes gas-bubble evolution from an aquatic plant directly observable.
• Comparative rate investigation: Allows bubbles to be counted over equal time intervals under different conditions.
• Plant physiology teaching: Supports practical study of photosynthesis, oxygen release and limiting factors.
• Controlled-variable experiments: Can be used to compare one selected factor while other conditions remain consistent.
• Data-recording activity: Enables students to tabulate bubble counts and present results graphically.
• Suitable for demonstrations: Provides teachers with a clear practical method for explaining photosynthetic activity.
• Reusable configuration: Reuse is subject to proper cleaning and the confirmed construction material.

How to Use Wilmott’s Bubbler

1. Clean the apparatus and inspect every vessel, tube and seal for damage.
2. Fill the apparatus with the liquid specified by the approved laboratory procedure.
3. Insert a suitable freshly prepared aquatic plant in the correct orientation.
4. Assemble the apparatus carefully and remove unintended trapped air.
5. Place the setup at a controlled distance from the selected light source.
6. Allow the plant to acclimatise before beginning the observation period.
7. Count the bubbles released during a fixed time interval.
8. Change only one experimental variable, repeat the measurement and compare the results.

Safety note: Wear suitable laboratory PPE. Keep electrical lamps and cables away from water, handle glass components carefully and avoid overheating the plant or apparatus. Follow an approved laboratory method when using any reagent.

Care & Maintenance

• Rinse the apparatus promptly after use to remove plant matter and experimental solution.
• Use a cleaning agent compatible with the confirmed construction material.
• Do not force tubes, stoppers or connectors during assembly or disassembly.
• Store the clean, dry apparatus in a protected cabinet to reduce impact damage.

Frequently Asked Questions

What is Wilmott’s Bubbler used for?

Wilmott’s Bubbler is used to observe and compare gas-bubble evolution by an aquatic plant during photosynthesis.

What do the bubbles represent?

The bubbles indicate gas released by the plant during photosynthetic activity. In the standard experiment, the evolved gas is treated as oxygen.

Does bubble counting measure the exact photosynthesis rate?

No. Bubble counting provides a comparative indicator because individual bubbles may differ in volume. An experiment requiring absolute gas volume needs suitable calibrated measurement equipment.

Which plant can be used with the apparatus?

A suitable aquatic plant should be selected according to the approved teaching protocol and local availability. The specimen is not confirmed as included.

Can students investigate the effect of light?

Yes. Students can compare bubble rates at controlled light levels or distances, provided they change only one variable and keep other conditions consistent.

Is Wilmott’s Bubbler suitable for school laboratories?

It is suitable for supervised plant-physiology demonstrations and biology practical work when used with an age-appropriate method and laboratory safety controls.
