Glass Tube (Open at Both Ends)
Glass Tube (Open at Both Ends) (Product Code: SCL-359/078) is a clear glass tube used for diffusion experiments in school and college science laboratories. Because it is open at both ends and offered in different diameters, gases or solutions can be introduced from each end and their meeting point observed through the glass. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer and lab glassware maker, at its own factory in Ambala, India.

What Is the Open Glass Tube Used For?
A classic demonstration clamps the tube horizontally, with cotton wool soaked in ammonia solution at one end and hydrochloric acid at the other, both inserted at the same moment. A white ring of ammonium chloride forms where the two gases meet, closer to the acid end, showing that the lighter ammonia molecules diffuse faster. Carry this out in a fume cupboard or a well-ventilated room under teacher supervision.
The clear glass lets the whole class watch the ring form, and measuring its distance from each end with a metre scale turns the demonstration into a quantitative exercise. Tubes of different diameters also suit simple liquid-diffusion set-ups and general open-tube work on physics and chemistry benches.
What to Specify When Ordering
- The diameter you need, since the tube is offered in different diameters.
- The length required, as it is not stated in the listing.
- Quantity per class, plus any stands or clamps to hold the tube.
OEM Manufacturer

Related Physics Lab Equipment
A diffusion demonstration needs the tube held steady, a way to measure distances and a timer. Items that support it:
- Iron Stand — clamps the tube horizontally during the experiment.
- Meter Scale 50 cm — measures how far each gas has travelled.
- Stop Clock — times how long the ring takes to appear.
- Visualising Osmosis & Diffusion Investigation — a related investigation for liquid diffusion.

Frequently Asked Questions
What is the Glass Tube (Open at Both Ends) used for?
The Glass Tube (Open at Both Ends) is used for diffusion experiments, such as the ammonia and hydrochloric acid demonstration in which a white ring forms where the two gases meet. Its open ends let substances be introduced from both sides at once.
What sizes is the open glass tube available in?
The Glass Tube (Open at Both Ends) is available in different diameters. The listing does not give specific diameters or lengths, so please tell us the size your experiment needs through the contact page and we will confirm what can be supplied.
Why is a clear glass tube used for diffusion demonstrations?
The Glass Tube (Open at Both Ends) is clear, so students can watch a diffusion front or white deposit form along its length and measure its position accurately. A coloured or frosted tube would hide exactly the change the experiment is meant to show.
Who manufactures the Glass Tube (Open at Both Ends)?
The Glass Tube (Open at Both Ends) is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), which is the OEM, at its own licensed factory in Saha, Ambala, Haryana, India. Schools and dealers get quotations and repeat supplies directly from the manufacturer.
How should the glass tube be handled and cleaned?
Handle the Glass Tube (Open at Both Ends) with both hands when inserting stoppers or cotton plugs, and never force a stopper in with a twisting push. After use, rinse it with water, drain it and let it dry before storage so no residue carries over to the next experiment.
Can the Glass Tube (Open at Both Ends) be ordered in class quantities?
Yes, the Glass Tube (Open at Both Ends) can be supplied in class quantities to schools, colleges, dealers and importers in India and international markets. Share the diameter, quantity and delivery location through the contact page for a quotation direct from the manufacturer.
