U-Tube Manometer
Product Code : SCL-CL-12361
U-Tube Manometer (SKU SCL-CL-12361) is a glass U-tube mounted on a white back panel with a scale, used to measure small differences in gas pressure by the difference in liquid level between its two limbs. Physics and chemistry teachers use it for pressure practicals in secondary school, junior college and first-year science labs. Science Lab Supplies sends it out from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
The manometer is a laboratory-grade glass U-tube with a built-in reservoir chamber and a built-in glass stopcock, all fixed to a 400 x 80 mm white plastic rear panel. A centre-zero scale reads 80–0–80 in 2 mm divisions, so the rise in one limb and the fall in the other are read directly.

Applications and Experiments for the U-Tube Manometer
The manometer turns a pressure difference into a visible height difference, which students read off the centre-zero scale. It is used to compare gas pressure with the atmosphere, to show pressure in lung or gas-supply models, and to introduce the idea that pressure depends on liquid depth and density.
- Class 11 physics (mechanical properties of fluids): gauge pressure and the relation p = hρg.
- Chemistry practicals: checking the pressure of a gas generator or laboratory gas line against the atmosphere.
- Middle-school science: showing that blowing gently on one limb moves the liquid by a measurable amount.
- B.Sc. and diploma labs: comparing readings taken with different manometer liquids.
Standard Scope of Supply
Each unit is the glass U-tube with its reservoir chamber and stopcock, fixed to the scaled rear panel as described above. The listing does not include the manometer liquid, so the laboratory fills it with coloured water or its chosen liquid; connecting tubing can be added to the quotation.
Packing, MOQ and Lead Time
You may ask for a single manometer or enough for every bench in the laboratory; the quotation then sets out packing, delivery time and price for that number. Rubber tubing, a vacuum pump or a barometer can be priced alongside, which is handy when sourcing school chemistry lab equipment in India in one order.
With a registered Importer-Exporter Code, Science Lab Supplies can ship to buyers in Peru, Egypt, Iraq, Nigeria, Kenya and Ghana. Questions and orders can be sent from the contact page or collected in the enquiry cart; institutions buying through tenders can start at the lab tender page.
Frequently Asked Questions
What does the 80–0–80 scale mean?
Zero sits at the centre with 80 graduations above and below it, marked in 2 mm divisions. Reading how far each limb moves from zero gives the total level difference, which is proportional to the pressure difference.
Is the manometer liquid included?
No liquid is listed with the unit. Schools usually fill it with coloured water; the liquid chosen changes the pressure represented by each millimetre of level difference.
Who supplies the U-Tube Manometer?
It is supplied by Science Lab Supplies from Ambala, India, which quotes, packs and dispatches the manometer for single classrooms, whole laboratories and tender buyers alike.
What is the stopcock for?
The built-in glass stopcock lets you open or close the connection to the tube, so the liquid can be levelled at zero before a reading and isolated between measurements.
Related Pressure Apparatus
Pressure lessons are clearer when students measure it in more than one way. These four items from the same range pair with the manometer for gas-pressure, vacuum and atmospheric-pressure practicals, and they can be listed on a single quotation.
- Aneroid Barometer — reads the atmospheric pressure the manometer is compared with.
- Manometer Cylinder with Piston Temperature Meter — gas pressure, volume and temperature work.
- Hand Vacuum Pump with Pressure Gauge — creates reduced pressure for demonstrations.
- Rubber Tube (Laboratory) — connects the manometer to a gas source.
