Reaction Tube
Product Code : EL-TT-10181
Lab Glassware Manufacturer manufactures and exports the Reaction Tube from its production base in Ambala, Haryana, in continuous operation since 1982, supplying school and college science laboratories, university and research departments, and export buyers that have recently included institutions in Papua New Guinea, Solomon Islands and Vanuatu — part of a wider base of enquiries from across Melanesia.
Quick answer: A Reaction Tube is a glass tube fitted with a standard-taper ground-glass socket, used to run small-scale chemical reactions that need to connect to other glassware — a condenser, adapter or dropping funnel — rather than being used open like a plain test tube. Lab Glassware Manufacturer's Reaction Tube has a 25ml capacity and a 14/20 socket.

When to Use a Reaction Tube
Choose a Reaction Tube over a plain test tube when the reaction needs to be run under reflux, under an inert atmosphere, or connected to a condenser, adapter or addition funnel through a ground-glass joint — the 14/20 socket is a common small-scale taper size compatible with a wide range of standard-taper glassware. Confirm the socket gender (this tube carries the socket, or female, side of the joint) when matching to other apparatus.
