Drying Column
Product Code : SCL-CL-11494
Drying Column (SKU SCL-CL-11494) is a 250 ml drying column for gases with an emery (ground) nozzle. Filled with a solid drying agent, it removes water vapour from a gas stream before the gas is collected, tested or passed into another reaction, which suits senior school chemistry demonstrations, B.Sc. gas practicals and technician training. Science Lab Supplies takes enquiries for it in Ambala, India from schools, colleges, training institutes, distributors and tender contractors, and quotes each one directly.
Specifications
The table shows the drying column’s specification, one fact to a row. In short, the column holds 250 ml of drying agent and is fitted with an emery nozzle, the ground finish that gives a close fit to the connecting part; gas passes through the packed desiccant and leaves dry.

Applications and Experiments for the Drying Column
A drying column can be placed between a gas generator and the point where the gas is used. Its 250 ml charge of desiccant, such as anhydrous calcium chloride or silica gel, can dry a steady flow of gas for a longer run than a 145 mm drying tube before it needs refilling.
- Class 11–12 chemistry: drying hydrogen made with the Simple Appliances for Cooking Gas Lighter than Air, or carbon dioxide from the Simple Appliances for Cooking Gases Heavier than Air.
- Demonstrating that a gas carries moisture, by comparing the desiccant before and after use.
- B.Sc. inorganic practicals: supplying dry gas to a reaction tube.
- Technician and diploma training: building and maintaining a gas-handling train.
Choose a desiccant that does not react with the gas, and treat gas generation, especially of hydrogen, as a supervised activity away from open flames.
Standard Scope of Supply
The Drying Column is supplied as a single empty column with its emery nozzle, as described above. The drying agent, stoppers and connecting tubing are not included and can be added to your quotation as separate lines, so the whole drying stage is priced together.
Packing, MOQ and Lead Time
Request a price for a single column or for every gas bench in the department, and the quotation will show packing, delivery time and price for the quantity requested. Gas generators, tubing and other chemistry lab equipment in India can be listed together.
Operating as a registered exporter with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Nepal, Bangladesh, Zambia, Rwanda, South Africa and Qatar. A drying column, its stoppers and tubing can be requested in one go through the enquiry cart, nozzle-size questions can go to the contact page, and public-sector buyers can refer to the lab tender page.
Frequently Asked Questions
How is a drying column different from a drying tube?
Both hold a solid desiccant to dry gases. This column holds 250 ml of drying agent, so it suits longer runs and larger gas flows than the 17 x 145 mm dryer pipe.
What does “emery nozzle” mean?
Emery refers to a ground finish on the nozzle, which gives a closer fit with the part it joins. For the exact connection size, ask us through the contact page before ordering.
Who supplies the Drying Column?
The column is priced by Science Lab Supplies from Ambala, India, which answers schools, colleges, training institutes and distributors whether they want a single unit or a bulk lot.
Is the drying agent included?
No. The column is supplied empty, so the laboratory can fill it with the desiccant that suits the gas being dried and replace it when spent.
Related Gas Generation and Drying Items
A drying column sits in a line that starts at a gas generator and ends at a collecting vessel. Dryer pipes, two Kipp-type generators, a chlorine apparatus with its own drying bottle, a safety tube, stoppers and rubber tubing from the Chemistry Lab range make up that line and can be quoted with the column.
- Dryer Pipes — 17 mm clear glass drying tube, 145 mm long, for smaller set-ups.
- Kipps Apparatus — funnel-ended upper pot over two joined glass flasks, 300 to 350 mm high.
- Simple Kipps Appliances — 6 ml Kipp-type generator operated with small amounts of substances.
- Apparatus for Cooking Chlorine, Hydrogen Chloride — 250 ml flask, two-bubble safety tube, delivery tube and 250 ml gas-drying bottle.
- Safety Tubes with Bubble — 350 mm tube with one bulb and a 40 mm upper opening.
- Rubber Stoppers of Various Diameters with Holes — holed, chemical-resistant stoppers in 11, 13, 14 and 15 mm bottom diameters.
- Rubber Tube (Laboratory) — can connect the column to a gas line; a 9 x 6 mm hose of natural rubber.
