Boiling Tubes Manufacturer,Supplier and Exporter in India

Boiling Tubes (Product Code: SCL-667/081) are wide, round-bottomed tubes of clear borosilicate glass, 150 x 25 mm with a rim, used when a reaction or a solution needs more room than an ordinary test tube provides. Their wider bore lets liquids boil more steadily with less risk of spurting, which is why chemistry teachers choose them for dissolving salts, preparing extracts and heating mixtures with reagents. The glass is heat resistant and chemical resistant, fitting the standard expected of borosilicate glassware in India's school and college labs. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

In salt analysis practicals a boiling tube is the natural vessel for making the original solution of a salt, boiling a mixture with sodium carbonate to prepare an extract, or warming a sample with dilute acid while watching for gas. Biology and chemistry teachers also use them to heat liquids in a water bath, to carry out tests that need a larger sample, and as the reaction vessel in simple gas-collection set-ups closed with a bored cork and a delivery tube. The round bottom spreads heat evenly, and the rim gives the holder a secure grip and helps when pouring the contents out.

Fill a tube only to about a third of its height before heating over a flame, hold it at a slant with a test tube holder and point the mouth away from everyone nearby. Warm the tube gently near the surface of the liquid while shaking slightly to prevent bumping, and never heat an empty tube. Between steps the tubes can rest upright in a test tube rack or stand; once cool, clean them with a brush and detergent and rinse with distilled water.

Boiling tubes are handled, held and cleaned with a few everyday accessories:

• Test Tube Holder — holds the tube at a safe angle over the flame.
• Test Tube Stand Poly Lab — keeps tubes upright between steps; check that the holes suit wider tubes.
• Test Tube Brush Nylon — reaches the round bottom when cleaning.
• Corks — close the tube or hold a delivery tube in gas experiments.
• Ignition Tubes — smaller tubes for strongly heating solid samples.

Frequently Asked Questions

What are the dimensions of these boiling tubes?
Each tube is 150 x 25 mm, with a rim at the mouth and a round bottom.

How is a boiling tube different from a test tube?
It is wider, so it holds a larger sample and lets liquids boil more steadily. Use it when a test tube would be too narrow or too full.

Can they be heated directly over a burner?
Yes. They are made of heat-resistant borosilicate glass. Heat gradually, keep the tube moving and never heat it dry.

How many tubes come in a pack?
Pack quantity is not specified in this listing. Tell us how many tubes you need through the contact page and we will quote accordingly.

How should they be cleaned?
Let them cool, scrub with a tube brush and detergent, rinse with tap water and then distilled water, and dry upside down.

Do you supply boiling tubes in bulk or for export?
Yes. ScienceLab supplies schools, colleges and dealers in India and international markets; include the quantity and destination in your enquiry.
