Hollow Glass Tubes Ordinary Manufacturer,Supplier and Exporter in India

Hollow Glass Tubes Ordinary (Product Code: SCL-691/091) are plain hollow tubes of clear borosilicate glass that students and lab assistants cut, bend and shape into the connecting pieces a chemistry set-up needs: delivery tubes, right-angle bends, jets and short links between flasks and rubber tubing. The glass is heat resistant and chemical resistant, so a finished piece can carry hot gases and vapours or sit in contact with acids and alkalis during an experiment. Schools buying from a lab glassware supplier in India often keep a stock of these tubes for the glass-working practical and for repairs to existing apparatus. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

In the classic glass-working exercise, students score a tube with a cutter, snap it cleanly, round the sharp ends in a flame, then soften a section and bend it to a right angle or draw it out into a fine jet. The finished pieces become delivery tubes for gas preparation, links in a simple distillation apparatus, or inlet and outlet tubes pushed through bored corks in flasks and boiling tubes. Because borosilicate softens at a higher temperature than soft soda glass, use the hottest part of a well-adjusted Bunsen flame, rotate the tube steadily while it heats, and let each piece cool slowly on a heat-proof mat rather than on a cold bench.

Most glass injuries in school labs happen while pushing tubing into a cork or rubber stopper. Wet the end of the tube or add a drop of glycerine, wrap your hand in a cloth, hold the tube close to the cork and ease it in with a gentle twist, never by pressing on a bend. Store unused lengths flat in a rack or box so they do not roll off the bench.

Related Chemistry Lab Equipment

Working with glass tubing needs a few tools and fittings:

• Glass Tubing Cutter — scores the tube so it snaps cleanly.
• Bunsen Burner — the flame for bending, drawing jets and rounding ends.
• Corks — bored to hold the finished tube in a flask or boiling tube.
• Rubber Tubing — flexible joins between glass sections.
• Delivery Tube — a ready-made alternative when there is no time to bend your own.

Frequently Asked Questions

What diameters and lengths are available?
Tube diameter, wall thickness and length are not specified in this listing. Share the sizes you need through the contact page and we will confirm availability.

Can the tubes be bent over an ordinary Bunsen burner?
Yes, with care. Borosilicate needs the hottest part of the flame and steady rotation; cool the bent piece slowly to avoid strain cracks.

How do I cut a tube safely?
Make one firm score with a cutter, wrap the tube in cloth, snap it away from your body and fire-polish both ends before use.

Are the tubes suitable for hot gases and chemicals?
They are made of heat-resistant and chemical-resistant borosilicate glass, suitable for routine gas delivery and connection work in school and college labs.

What details does an institutional quotation need?
The quantity, preferred sizes, delivery address and any vendor-registration or tender format your institution requires.

Do you supply larger quantities or export?
Yes. ScienceLab supplies schools, colleges and dealers in India and international markets.
