What Is Laboratory Rubber Tubing Used For?
Rubber tubing is the flexible link in many set-ups: it joins a glass delivery tube to a second piece of glassware, carries cooling water to and from a condenser, connects a burner to the gas tap, and lets a gas generator feed a trough or gas jar without rigid glass bends. With a pinch or screw clamp fitted, it also works as a simple valve to stop or regulate flow.
To fit it, moisten the end of the glass tube with water or a little glycerol and ease the rubber on with a twisting motion, protecting your hand with a cloth; never force it. Keep the tube within its −25 °C to +70 °C rating, away from flames and hot plates, and check the suitability of natural rubber before using it with oils or organic solvents. Replace any length that has become hard, sticky or cracked, particularly on gas lines.
What to Specify When Ordering
- The total length or number of pieces needed; ask us how the tubing is supplied.
- The outer diameter of the glass tubes or nozzles it must fit, to check against the 6 mm bore.
- Any use outside −25 °C to +70 °C, or with vacuum or solvents, so that a different tubing can be considered.
- Clamps for closing or regulating the tube.

What temperatures can the tube handle?
The Rubber Tube (Laboratory) is listed for use from −25 °C to +70 °C. It should not carry steam or boiling liquids, and it must be kept away from flames and hot surfaces during experiments.
Can it connect a Bunsen burner to the gas tap?
The Rubber Tube (Laboratory) can link a burner to the gas tap where both nozzles suit its 6 mm bore. Route it clear of the flame, secure both ends and replace the tube as soon as it hardens or cracks.
Is it suitable for vacuum filtration?
The Rubber Tube (Laboratory) is not described as vacuum tubing, so it may flatten under suction. For vacuum filtration with a Büchner funnel and filter flask, choose thick-walled vacuum tubing instead.
