Dryer Pipes
Product Code : SCL-CL-11487
Dryer Pipes (SKU SCL-CL-11487), also called drying tubes, are clear glass tubes 17 mm in diameter and 145 mm long. Packed with a solid drying agent, they remove moisture from a gas passing through or stop damp air reaching a reaction, which suits gas-preparation practicals in senior secondary chemistry and in college labs. Science Lab Supplies quotes them out of Ambala, India to schools, colleges, training institutes and distributors, and tender quantities can be priced on request.
Specifications
Every dimension and property of the dryer pipe appears in its own table row. In short, it is a clear glass tube of 17 mm diameter and 145 mm length that can hold a charge of granular desiccant between two plugs of cotton wool, and the glass is resistant to chemicals and to heat.

Applications and Experiments for Dryer Pipes
A drying tube can sit in a gas line or on top of a flask. Filled with a desiccant such as anhydrous calcium chloride, it takes water vapour out of a gas before the gas is collected or tested, or keeps moist air away from a reaction that must stay dry.
- Class 11–12 chemistry: drying gases prepared in the laboratory before collection, for example in a train built from the Apparatus for Cooking Chlorine, Hydrogen Chloride.
- Demonstrating that a gas contains water vapour by weighing the tube before and after.
- B.Sc. organic practicals: a guard tube on top of a Straight Cooler (Condenser) used for reflux, to exclude moisture.
- Diploma and technician training: assembling gas-handling trains.
Choose a drying agent that does not react with the gas being dried, replace it when it is spent, and handle desiccants and toxic gases with care under supervision.
Standard Scope of Supply
Dryer Pipes are supplied as empty glass tubes of the size shown above. The drying agent, cotton wool, stoppers and connecting tubing are not included; they can be quoted separately if you add them to your enquiry for the same quotation.
Packing, MOQ and Lead Time
Request a quotation for one tube or a batch for every workbench; Science Lab Supplies replies with the packing, delivery time and price for that quantity. As a chemistry lab instruments supplier it can add stoppers, tubing and drying columns to the same quotation.
As a registered exporter under an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Ethiopia, Tanzania, Uganda, the UAE, Saudi Arabia and Oman. Ask about stopper sizes or request a price for the dryer pipes on the contact page, collect a full gas-drying list in the enquiry cart, or open the lab tender page for tender purchases.
Frequently Asked Questions
What are dryer pipes used for?
They hold a solid desiccant that dries a gas flowing through the tube or protects a reaction from atmospheric moisture. In many textbooks the same item is called a drying tube.
Is a drying agent supplied with the tube?
No. The tube is supplied empty, so the laboratory fills it with the desiccant suited to its experiment, held in place between two cotton-wool plugs.
Who supplies the Dryer Pipes?
These tubes are priced and sent by Science Lab Supplies from Ambala, India, which takes enquiries from institutions and distributors for single pieces or larger lots.
How is the tube connected to apparatus?
Fit it through a bored rubber stopper or join it with rubber tubing. Our team can advise on matching stopper sizes through the contact page before you order.
Related Gas-Drying and Gas-Generating Glassware
A gas-drying train can combine a gas generator, a drying stage and fittings that join them. A larger drying column, two gas generators, a desiccator, a safety tube, stoppers and rubber tubing from the Chemistry Lab and Lab Glassware ranges complete such a set-up and can be quoted with the dryer pipes.
- Drying Column — 250 ml column for drying gases, with an emery nozzle.
- Kipps Apparatus — classic Kipp generator of 250 ml volume that produces gases without heating.
- Simple Kipps Appliances — 6 ml Kipp-type device built from a test tube with a side tube.
- Glass Desiccator — enclosed glass chamber in which a desiccant keeps samples dry.
- Safety Tubes with Bubble — safety tube with one bulb, 40 mm across at the top and 350 mm in length.
- Rubber Stoppers of Various Diameters with Holes — rubber stoppers with a hole in 11, 13, 14 and 15 mm sizes.
- Rubber Tube (Laboratory) — natural rubber hose, 9 mm outside diameter.
