Laboratory Glass Round Bottom Flask Manufacturer,Supplier and Exporter in India

Product Code : SCL-B-12583

The Laboratory Glass Round Bottom Flask is a 100 mL narrow-neck glass flask used for heating, boiling, mixing, and holding compatible laboratory liquids during supervised chemistry practicals. It is suitable for schools, colleges, science departments, laboratory technicians, distributors, and institutional procurement buyers.

Product Description

Laboratory Glass Round Bottom Flask from School Equipments India is based on the verified official listing for Glass Round Bottom, Narrow Neck Flask 100ml. The listed flask has a round-bottom body, narrow neck, and beaded rim, and is also described as a boiling flask.

The verified listing specifies 100 mL capacity, 65 mm body diameter, 115 mm height, 18 mm neck diameter, and bung size 17. It also states that the flask offers high resistance to thermal shock and excellent chemical durability. Exact glass grade, tolerance, heat-use limit, stopper inclusion, and certification should be confirmed before tender submission.

Key Features

• 100 mL verified capacity: suitable for small-scale chemistry practicals and laboratory demonstrations.
• Round-bottom design: supports uniform heating and boiling where the laboratory method permits.
• Narrow neck: helps reduce splashing during swirling, boiling, and reagent handling.
• Beaded rim: supports practical pouring, handling, and stopper use.
• High thermal-shock resistance: stated on the verified School Equipments India listing.
• Excellent chemical durability: suitable for compatible laboratory liquids under supervised conditions.
• Bung size 17: supports use with compatible stoppers where the practical requires closure.

• Teaching boiling, vapour formation, thermal transfer, and reaction setup handling
• Supporting tender-based procurement for laboratory flasks and glassware

How to Use the Laboratory Glass Round Bottom Flask

1. Inspect the flask for cracks, chips, scratches, residue, or rim damage.
2. Confirm that 100 mL capacity and bung size 17 match the practical method.
3. Support the round-bottom flask with a clamp, flask holder, cork ring, or heating mantle.
4. Add compatible liquid below the safe working level; do not fill to the rim.
5. Heat only if the laboratory SOP permits the method and setup.
6. Never seal the flask during heating, boiling, distillation, or gas-producing reactions.
7. Allow the flask to cool gradually before washing or storage.
8. Clean, rinse, dry, and store the flask in a protected glassware cabinet.

Safety note: Use only under trained supervision. Do not heat sealed glassware, expose the flask to sudden temperature change, or use damaged glassware with hazardous chemicals.

Care & Maintenance

• Clean immediately after use to prevent residue, staining, and chemical build-up.
• Avoid abrasive brushes or hard tools that may scratch the glass surface.
• Store with neck and rim protected from impact.
• Use a cork ring or suitable rack when placing the round-bottom flask on the bench.
