What Is the Delivery Tube Used For?
The two right-angle bends let the tube rise out of a stoppered vessel, run sideways and drop into a second vessel standing beside it. Typical set-ups include passing the gas from fermenting yeast and sugar solution into lime water, which turns milky with carbon dioxide, and showing that the gas released when a metal carbonate reacts with dilute acid does the same. To fit it, wet the end with water or glycerine, hold the tube close to the stopper through a cloth and push it in with a gentle twist — never force it, as glass tubing snaps under side pressure. Lift the tube out of the lime water before any heating stops, so the liquid is not sucked back into the hot vessel.

OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, a laboratory glassware manufacturer in India, incorporated in 2017 and operating from Hargolal Road, Ambala, Haryana. The delivery tube is made in JLab’s own works, not bought from a trader, so schools, colleges, dealers and importers buy it factory-direct. JLab exports worldwide and ships to buyers in every region — for example Algeria in North Africa, Cyprus in Southern Europe, the USA in North America, Vietnam in Southeast Asia and the Dominican Republic in Central America and the Caribbean.
