Applications and Experiments for the Laboratory Rubber Tube
Rubber tubing is a basic connector in practicals that move gas or water between pieces of apparatus. In schools it links Bunsen burners and delivery tubes; in colleges it carries cooling water through condensers and connects filter flasks. It suits CBSE/NCERT Class 8–12 practicals and B.Sc. chemistry laboratories.
- Class 8–10 science: connecting Bunsen burners and gas delivery tubes in preparation of gases.
- Class 11–12 chemistry: water lines for a Straight Cooler (Condenser) during distillation.
- B.Sc. chemistry: vacuum filtration with the Equipment for Vacuum Filtration set and general apparatus connections.
Keep the tubing away from direct flame and hot surfaces above its rated range, and replace any length that has become cracked or sticky before connecting it to a gas supply.
