Absorption Tube with Side Arms Manufacturer,Supplier and Exporter in India

Absorption Tube with Side Arms (Product Code: SLE/CH/182) is a heavy walled, clear borosilicate glass U-tube fitted with side arms of approximately 6mm diameter, so it can be plugged straight into a gas train with flexible tubing. It is used by chemistry departments and analytical teaching labs to dry a gas or absorb a component such as water vapour or carbon dioxide while the gas flows continuously through the packing. This piece of borosilicate laboratory glassware in India is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

With side arms, the gas connections and the filling openings are separate. The absorbent is poured in through the top of each limb, held with a small plug of glass wool and sealed with solid stoppers, while the incoming and outgoing gas lines slide onto the side arms. When the packing is spent, the stoppers come out for refilling without disturbing the tubing, which saves time when a gas train has several stages such as washing, drying and absorption in sequence.

This layout suits combustion and absorption experiments, where one tube collects water and a second collects carbon dioxide, and each is weighed before and after to find the mass absorbed. The heavy walls stand up to repeated handling, and the transparent glass lets the operator watch the absorbent change as it works through the tube. Support the tube with a clamp rather than letting it hang on the tubing, and slide tubing onto the side arms gently with a little water as a lubricant to avoid strain on the glass.

Frequently Asked Questions

What size are the side arms?
They are approximately 6mm in diameter. Choose flexible tubing whose bore grips that size snugly.

What is the overall length of the tube?
An overall length is not stated in our product details. Please ask through our contact page if the tube must fit a particular set-up.

Why choose side arms instead of a plain U-tube?
Side arms keep the gas connections separate from the filling openings, so the absorbent can be changed without dismantling the tubing.

Is the glass suitable for warm gases and reactive absorbents?
Yes. It is heavy walled borosilicate glass that is heat resistant and chemical resistant; still avoid sudden temperature shocks.

Are stoppers included?
Stoppers are not listed with this tube. We can quote suitable ones on request.

What should a laboratory include in a quotation request?
The quantity, any accessories wanted and the delivery address. We supply institutions in India and international markets.
