Product Code : SCL-CL-11541
Rubber Tube (Laboratory) (SKU SCL-CL-11541) is a natural rubber laboratory hose with a 6 mm inner and 9 mm outer diameter, used to connect Bunsen burners to gas taps, carry cooling water to condensers and link glass tubing in gas-preparation set-ups. It is rated for use from −25 °C to +70 °C. Science Lab Supplies ships this tubing from Ambala, India to schools, colleges, laboratories, tender contractors and distributors.
Specifications
The tube is made from natural rubber, which keeps it flexible enough to push over glass and metal nozzles. Its bore is 6 mm and its outside diameter 9 mm, giving a 1.5 mm wall. The listing describes it as heat resistant within a working range of −25 °C to +70 °C.

Applications and Experiments for the Laboratory Rubber Tube
Rubber tubing is a basic connector in almost every practical that moves 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 condensers during distillation.
- B.Sc. chemistry: vacuum filtration and general apparatus connections.
Keep the tubing away from direct flame and hot surfaces above its listed range, and replace any length that has become cracked or sticky before connecting it to a gas supply.

Related Tubing Accessories
Rubber tubing is rarely used alone. The four items below are the usual partners on the bench: two clamps for controlling flow through the tube, bored stoppers that hold glass tubing, and glass tubes in different diameters to join with the hose.
- Screw Pipe Clamp (Hoffman Clamp) — adjusts flow through the tube.
- Elastic Clamp for Rubber Pipes (Mohr Clamp) — pinches the tube shut quickly.
- Rubber Stoppers of Various Diameters with Holes — hold glass tubing in flasks.
- Glass Tubes of Different Diameters — rigid sections joined by the hose.
