Capillary Tubes Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12522
Jlab Export is a leading Capillary Tubes Manufacturer,and suppliers in India
Capillary Tubes (code EL-PL-12522) are clear borosilicate glass tubes of 1 mm diameter for capillary rise practicals, in which water climbs a narrow bore because of surface tension. The glass is heat and chemical resistant. JLab, in Ambala, India, is the maker of these tubes.

Measuring Surface Tension by Capillary Rise
Clamp a clean tube upright with its lower end in water. Water wets glass and rises to a height h = 2T cos θ / (rρg), where T is the surface tension, θ the contact angle (close to zero for clean glass and water), r the bore radius and ρ the density. Read h with a travelling microscope from the flat water surface to the bottom of the meniscus, then measure the bore. Because h varies inversely with r, halving the radius doubles the rise. Grease cuts the rise, so clean the tube thoroughly and rinse it before use.
