Simple Glass Manometer
Product Code : LSK-BL-10143
Simple Glass Manometer (SKU LSK-BL-10143) is a plain glass manometer with a 2 mm bore tube held to a clear acrylic base by a locking bar; the whole unit measures 140 x 70 mm. Graph paper can be mounted behind the tube, so students draw or choose their own scale and read small changes in liquid level directly. It suits respiration, gas-exchange and simple pressure practicals. It is available as school and college biology lab equipment in India and abroad through Science Lab Supplies, Ambala, which quotes for institutions, tender contractors and distributors.
Specifications
Each feature of the 2 mm bore manometer has its own row in the table. In short, it is a simple glass tube with a 2 mm bore, clamped by a locking bar to a clear acrylic base of 140 x 70 mm, designed so that graph paper can be placed behind it as a reading scale.

Applications and Experiments for the Simple Glass Manometer
Connected by tubing to a sealed chamber, the manometer shows small pressure changes as a shift in its liquid column, which is how respirometers measure oxygen uptake by germinating seeds or small animals. It fits Class 11 biology respiration practicals, B.Sc. physiology and basic physics pressure demonstrations.
- Class 11 biology: measuring the rate of respiration of germinating seeds or small invertebrates in a home-made respirometer.
- B.Sc. plant and animal physiology: comparing gas exchange at different temperatures against a control tube.
- Physics: showing that a liquid column responds to small pressure differences.
- Filling the tube: adding coloured liquid with a glass Dropper and measuring volumes with Graduated Pipettes of 10 ml capacity.
Handle the glass tube with care, keep the locking bar tight before connecting tubing, and replace the graph paper scale whenever it becomes wet or marked.
Standard Scope of Supply
You receive the Simple Glass Manometer as one unit: the 2 mm bore glass tube clamped to its clear acrylic base with the locking bar. Graph paper, manometer liquid, connecting tubing and respirometer chambers are not included, and any of these can be quoted separately.

Frequently Asked Questions
What size is the Simple Glass Manometer?
The unit measures 140 x 70 mm. Its glass tube has a 2 mm bore and is held to a clear acrylic base by a locking bar, with space behind it for graph paper.
Why mount graph paper behind it?
Graph paper behind the clear base acts as a scale, so students can read the movement of the liquid column in small, even steps and record it during timed readings.
How does it differ from a respirometer?
The Respirometer is a complete unit with two stoppered boiling tubes connected by three-way taps to a graduated manometer. This item is the manometer alone, for building or repairing a set-up.
Who supplies this manometer?
Science Lab Supplies, operating from Ambala, India, quotes and ships the manometer and can include respirometers, potometers and other biology lab equipment in the same order.
