Lung Volume Bags, Plastic Transperent

Quick answer: Lung Volume Bags are graduated, transparent plastic bags used in physiology practicals to measure a person’s vital capacity — the volume of air exhaled in a single forced breath — up to 6 litres. Lung Volume Bags, Plastic Transparent is priced at approximately ₹175 (indicative market benchmark, incl. GST, August 2026).

Lung Volume Bags provide a simple, non-invasive way to measure vital capacity in a physiology or biology teaching lab. A student exhales in a single forced breath into the transparent, graduated bag through a mouthpiece, and the volume of air collected can be read directly off the bag’s markings, up to a stated capacity of 6 litres. Because the bag is transparent and graduated, results are visible immediately without needing separate calculation equipment, making it a straightforward tool for comparative respiratory experiments — comparing vital capacity across individuals, or before and after exercise — as part of standard physiology and human biology coursework.

Technical Specifications

Applications

• Measuring vital capacity (single-breath exhaled lung volume) in physiology practicals
• Comparative respiratory experiments across students or before/after physical activity
• Classroom demonstration of lung-volume concepts in human biology coursework
• General non-invasive respiratory-measurement teaching tool for schools and colleges

Care & Maintenance

• Use a fresh or sanitised mouthpiece for each student to maintain hygiene in shared classroom use
• Handle the bag gently to avoid tears or punctures that would affect the volume reading
• Store flat and away from sharp objects or heat sources that could damage the plastic

Frequently Asked Questions

What does a Lung Volume Bag measure?

It measures vital capacity — the volume of air a person can forcibly exhale in a single breath — read directly from the bag’s graduated markings, up to 6 litres.

Is this test invasive or does it require special training?

No — it is a simple, non-invasive single-breath test suitable for classroom use with basic instruction on correct exhalation technique into the mouthpiece.

Can this be reused across multiple students?

Yes, with a fresh or sanitised mouthpiece used for each student to maintain hygiene; the bag itself is reusable across sessions when handled and stored carefully.

What kind of experiments is this used for?

Common uses include comparing vital capacity across individuals, tracking changes before and after exercise, and general lung-volume demonstrations in physiology coursework.

Are exact bag dimensions and material specifications available for tender documentation?

Exact bag dimensions and plastic-grade specifications have not been independently verified for this listing. Institutions preparing tender documents should confirm precise specifications directly with STEMAids before finalising procurement paperwork.

Is STEMAids a registered manufacturer of this product?

Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
