Round Bottom Flask Short Neck - 250ml Manufacturer,Supplier and Exporter in India

Product Code : EL-CA-11595

The Round Bottom Flask Short Neck 250ml is chemistry laboratory glassware used for heating, boiling, reflux, reaction, evaporation, and distillation-related experiments. It is suitable for schools, colleges, universities, chemistry laboratories, science practical rooms, laboratory suppliers, distributors, and educational procurement buyers.

Product Description

The Round Bottom Flask Short Neck - 250ml from School Equipments India is intended for laboratory procedures where uniform heating and stable liquid circulation are required. The supplied product name confirms a round-bottom flask with short neck and 250 ml capacity; glass grade, neck type, joint size, dimensions, and heat rating must be confirmed before final publication.

A 250 ml round bottom flask is commonly used in chemistry teaching setups for boiling liquids, reflux work, solution preparation, reaction observation, and distillation assemblies. The rounded base helps distribute heat more evenly than flat-bottom vessels when supported correctly with a clamp, ring support, heating mantle, or suitable bath.

Key Features

• 250 ml capacity: suitable for medium-volume school and college chemistry experiments.
• Round-bottom profile: supports uniform heating when used with proper laboratory support.
• Short neck design: useful for compact reaction, boiling, and distillation-related assemblies.
• Chemistry practical use: supports heating, reflux, evaporation, preparation, and reaction work.
• Educational glassware: appropriate for supervised school, college, and STEM laboratory practicals.
• Material to verify: glass grade must be confirmed before claiming borosilicate or heat resistance.
• Specification-dependent compatibility: stopper size, joint type, and heating method must be verified before use.

How to Use the Round Bottom Flask Short Neck 250ml

1. Confirm the glass grade, neck type, stopper size, and experiment compatibility.
2. Inspect the flask for cracks, chips, scratches, or stress marks before use.
3. Add the required liquid without exceeding the 250 ml capacity.
4. Support the flask securely with a clamp, ring support, heating mantle, or suitable bath.
5. Attach only compatible stoppers, condensers, adapters, or receiving apparatus.
6. Heat gradually only if the material and thermal suitability are verified.
7. Allow the flask to cool before handling, cleaning, or dismantling the setup.
8. Wash, rinse, dry, and store the flask after the experiment.

Safety note: Wear goggles, gloves, and a lab coat when using chemical glassware. Do not heat closed glassware, place a filled round bottom flask directly on a flat bench, force incompatible joints, or use chipped or cracked glassware.

Care & Maintenance

• Rinse immediately after use to prevent chemical residue from drying inside.
• Clean with suitable laboratory detergent and non-abrasive brushes.
• Store in padded or compartmentalized storage to protect the neck and round body.
• Remove from use if cracks, chips, joint damage, clouding, or chemical etching appears.
