Set of Capillary Tubes Manufacturer,Supplier and Exporter in India

Set of Capillary Tubes (Product Code: SCL1240/016) is a device of three interconnected tubes, each 20 cm long, with different diameters of 1 mm, 1.5 mm and 2 mm, mounted on a plastic stand. When coloured water is poured in, the liquid settles at different heights in the three tubes – highest in the narrowest – so capillarity and surface tension become visible at a glance. The set is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, for any school running a capillary tube experiment in India.

Specifications

Typical Use

Because the tubes are connected, students might expect the water to stand at one common level, as it does in ordinary communicating vessels. Instead, it climbs highest in the 1 mm tube, less in the 1.5 mm tube and least in the 2 mm tube. Measuring each height with a ruler lets the class show that the rise gets larger as the bore gets smaller, which introduces the balance between surface tension pulling the liquid up and the weight of the raised column pulling it down. The same effect explains water moving up through soil, paper towels, lamp wicks and the fine vessels of plants.

Clean tubes are essential: any trace of grease lowers the rise and makes the levels uneven, so rinse with clean water after use and let the set drain and dry upright on its stand. A drop of food colour makes the meniscus easy to see from the back of the room. Alongside other surface tension apparatus in India's school physics labs, the set gives a quick, reliable demonstration that needs no power or pump.

Manufacturer

Frequently Asked Questions

What are the tube sizes?
Three tubes, each 20 cm long, with diameters of 1 mm, 1.5 mm and 2 mm, joined together and mounted on a plastic stand.

Why does water rise highest in the narrowest tube?
Surface tension lifts the liquid around the edge of the meniscus, and in a narrower tube that lift supports a taller column relative to its weight, so the rise is greater.

Which liquid works best?
Clean water with a little colouring is ideal for class use and makes the levels easy to compare.

How should the set be cleaned?
Rinse with clean water after each use, avoid oily or greasy substances, and let it drain upright on its stand. Do not push anything into the fine tubes.

What are the tubes made of?
The tube material is not listed in the current specification. Please ask through the contact page if your order needs it confirmed.

Can you supply sets for every lab group?
Yes. We quote class sets and bulk quantities for schools, colleges and distributors in India and international markets.
