What Is a Glass U-Tube Used For?
A U-tube is one of the simplest pieces of school lab glassware for showing how liquids behave under pressure. Pour coloured water into it and the level settles at the same height in both arms, because the pressure at the bend must balance. Add a liquid that does not mix with water, such as oil, to one arm and the two columns stand at different heights; measuring each height above the interface lets students compare the densities of the two liquids. With rubber tubing pushed over one arm, the same tube becomes a simple manometer that shows the pressure of a gas supply or of air blown into it. In chemistry, a U-tube filled with potassium chloride or potassium nitrate set in agar serves as the salt bridge between the two half-cells of a zinc–copper cell in class 12 electrochemistry practicals.
Clamp the tube upright when taking readings and read each level at the bottom of the meniscus. Because the glass type is not stated, do not heat the tube over a flame unless JLab confirms it is borosilicate. Wash it out after each class and let it drain upside down.
What to Specify When Ordering
- Size — check that the listed 125 x 15 mm suits your stand, clamps and any beakers it must bridge.
- Glass type — ask whether it is soda or borosilicate glass if you plan to heat it or use hot solutions.
- Quantity — the minimum order is 10 units; allow one per bench or group plus spares for breakage.
- Accessories — add stoppers, rubber tubing or glass tubing to the same enquiry.
Frequently Asked Questions
What is a glass U-tube used for in a school lab?
It shows that a liquid finds its own level, lets students compare the densities of two liquids that do not mix, works as a simple manometer with rubber tubing on one arm, and can be filled with salt solution in agar to make a salt bridge.
What size is this U-tube?
It is listed as 125 x 15 mm. The listing does not say which measurement is the height and which is the tube diameter, so confirm both with JLab before you order stoppers or plan a set-up around it.
Is it made of borosilicate glass?
The listing states glass only. Ask JLab to confirm the glass type in the quotation if you need to heat the tube or use it with hot liquids.
Are stoppers or rubber tubing included?
No, this listing covers the U-tube. Rubber stoppers and rubber tubing are separate items, linked below, and can go on the same enquiry.
What information is needed for an export quotation?
Send the quantity, the destination country and port or city, your preferred delivery terms such as FOB or CIF, any packing or labelling needs, and the tender reference if there is one.
Who manufactures this U-tube?
Jain Laboratory Instruments Pvt Ltd (JLab) makes it at its works in Ambala, Haryana, and quotes for it directly.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a maker of school science equipment and lab glassware in India, incorporated in 2017 and based on Hargolal Road, Ambala, Haryana. The U-tube comes from JLab’s own works rather than from a trader, so schools, colleges, dealers and importers can order it factory-direct alongside the rest of their lab glassware; every tube is visually inspected before dispatch, and repeat orders are handled by the manufacturer. JLab exports worldwide and ships to buyers in every region — for example Kyrgyzstan in Central Asia, Laos in Southeast Asia, Costa Rica in Central America and the Caribbean, Slovakia in Eastern Europe and Lesotho in Southern Africa.
Tubing, Stoppers and Pressure Apparatus
- U-Tube Manometer — a U-tube mounted on a polished wooden stand with metric graduation, for measuring pressure.
- Rubber Tubing — flexible lab rubber tubing for connecting the U-tube to a gas tap or other apparatus.
- Stopper — assorted rubber stoppers in solid, one-hole and two-hole types.
- Glass Tubing — soda glass tubing and capillary for making connections and bends.
- Bent Glass Tube — clear borosilicate glass, heat and chemical resistant.
