Respiration Apparatus Manufacturer,Supplier and Exporter in India

Respiration Apparatus (Product Code: SLE/BL/039) is a two-tube glass set-up used to compare inhaled and exhaled air in school biology lessons on respiration. It comprises two stoppered boiling tubes with one short and one long length of 5 mm glass tubing, joined by PVC tubing and a plastic T, and is listed for testing inhaled and exhaled air in small organisms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer of biology lab equipment in India, at its own factory in Ambala.

Specifications

What Is the Respiration Apparatus Used For?

Both tubes are part-filled with a carbon dioxide indicator such as limewater; in each stopper the long glass tube reaches below the liquid and the short one stays above it. The PVC tubing links the plastic T to the short tube of one boiling tube and the long tube of the other, so that air drawn in bubbles through the first tube on its way in and air breathed out bubbles through the second. Because exhaled air carries more carbon dioxide, the indicator in the "out" tube changes first — limewater turns milky, for example — giving a clear side-by-side comparison in a single lesson.

Before anyone breathes through the T-piece, the teacher should check which tube is which, since an assembly error can draw liquid towards the mouth. Breathe gently, use a clean mouthpiece for each person and rinse the tubes after the lesson. A standard item on any school lab instruments list, the apparatus also supports follow-on discussion of how the same comparison applies to other organisms that respire.

What to Specify When Ordering

• The number of sets — each has two stoppered boiling tubes, short and long 5 mm glass tubing, PVC tubing and a plastic T.
• Whether spare boiling tubes or bored stoppers should be quoted with the sets.
• Whether you need lime water or another carbon dioxide indicator, as none is listed with the apparatus.

Frequently Asked Questions

What parts make up the Respiration Apparatus?
The Respiration Apparatus comprises two boiling tubes, each with a stopper, and two lengths of 5 mm glass tubing, one short and one long, connected by PVC tubing and a plastic T. Together these let air be drawn in through one tube and breathed out through the other.

Is limewater or indicator supplied with the Respiration Apparatus?
No indicator is listed as part of the Respiration Apparatus. Lime Water is available separately in our range, and your syllabus may suggest another carbon dioxide indicator; mention it in your enquiry and we will add it to the quotation.

What diameter is the glass tubing of the Respiration Apparatus?
The glass tubing of the Respiration Apparatus is 5 mm. In use, the long length dips below the indicator liquid while the short length stays above it, so that air bubbles through the liquid in one direction only.

How should students breathe through the Respiration Apparatus?
Students should use the Respiration Apparatus only under teacher supervision: check the tube arrangement first, breathe gently and give each person a clean mouthpiece. Nobody should suck hard on the T-piece, because an assembly error can draw liquid towards the mouth.

Can I get spare tubes and stoppers for the Respiration Apparatus?
Boiling tubes and bored stoppers for the Respiration Apparatus are listed separately in our range, as shown above. For replacement 5 mm glass tubing, PVC tubing or plastic T-pieces, contact us and we will confirm what can be quoted.

Who manufactures the Respiration Apparatus?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM manufacturer of the Respiration Apparatus (SLE/BL/039). It is made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers.
