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. It suits pressure practicals in physics and chemistry at secondary school, junior college and first-year science level. Quotations for one unit or a full set of benches come from Science Lab Supplies in Ambala, India, for institutions, tender contractors and distributors.

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 can be used to compare gas pressure with the atmosphere, to check the pressure of a gas source, 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, after showing that pressure rises with depth on the Fluid Pressure Apparatus (Spouting Cylinder).
- Chemistry practicals: checking the pressure of gas produced in a Kipps Apparatus or from a 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: reading small pressure differences produced with a Hand Vacuum Pump and comparing readings taken with different manometer liquids.
Standard Scope of Supply
Each unit is the glass U-tube with its built-in reservoir chamber and glass stopcock, fixed to the 400 x 80 mm white plastic rear panel carrying the 80–0–80 scale. A filling liquid and connecting tubing can be added to the same quotation if your practical needs them.
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. To price the manometer, write to the team from the contact page, collect it with other pressure items in the enquiry cart, or open the lab tender page if your institution buys through tenders.
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.
Which liquid goes in the manometer?
The laboratory chooses the filling liquid, for example coloured water. The density of the liquid sets the pressure represented by each millimetre of level difference, so record which liquid was used with every reading.
Who supplies the U-Tube Manometer?
This manometer is quoted, packed and dispatched by Science Lab Supplies of Ambala, India, whether the request is one classroom unit, a set for a whole laboratory or a line in a tender.
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.
