Product Code : SCL-CL-11698
Round Bottom Pots (Spherical Flasks) (SKU SCL-CL-11698) are 500 ml round-bottom glass flasks with a long neck, used for heating, boiling and distilling liquids where even heat distribution matters. The spherical body spreads heat and stress uniformly, so these flasks are standard for distillation and reflux set-ups in school and college chemistry. Science Lab Supplies, from its base in Ambala, India, puts them on quotations for schools, colleges, laboratories, distributors and tender contractors.
Specifications
Each flask is a transparent glass sphere of 500 ml capacity with a round bottom and a long mouth, or neck, that takes a stopper, adapter or thermometer. The glass is listed as heat resistant and chemical resistant, which suits heating over a mantle or gauze and contact with common reagents.

Applications and Experiments for the Round Bottom Flasks
The 500 ml round-bottom flask holds a liquid while it is boiled, distilled or refluxed, and it can be clamped at the neck with the body resting in a heating mantle. It forms the boiling vessel of most distillation and reflux assemblies used in teaching laboratories.
- NCERT Class 9 science: separating miscible liquids or purifying water by distillation.
- CBSE Class 11 and 12 chemistry: simple distillation and the preparation of organic compounds.
- B.Sc. organic chemistry: heating reaction mixtures under reflux with a condenser.
Always clamp the flask at the neck, add anti-bumping granules before boiling, and never heat a closed system.
Standard Scope of Supply
The Round Bottom Pots (Spherical Flasks) are supplied as individual 500 ml long-neck glass flasks, as described above; any optional accessories are listed on the quotation. Condensers, stoppers, clamps and heaters are separate items and can be quoted with the flasks.
Packing, MOQ and Lead Time
Ask for one flask or a full set for a distillation practical; the quotation lists the packing, delivery time and price for the quantity you specify. Condensers and heaters for laboratory distillation apparatus in India can be priced on the same quotation to build a complete assembly.
Science Lab Supplies is a registered exporter holding an Importer-Exporter Code and can ship to buyers in Sri Lanka, Vietnam, Malaysia, Peru, Egypt and Iraq. Get in touch via the contact page, add products to the enquiry cart, or find tender guidance on the lab tender page.
Frequently Asked Questions
Why use a round-bottom flask rather than a flat-bottom one?
A round bottom heats evenly and resists the stresses of boiling and reduced pressure better than a flat base. The flask needs a clamp, ring or heating mantle to stand upright.
What is the capacity and neck style?
Each flask holds 500 ml and has a long neck. The long neck keeps the stopper or adapter away from the hot liquid and gives room for a clamp.
Who supplies the spherical flasks?
These flasks are supplied from Ambala, India by Science Lab Supplies, which quotes schools, colleges, resellers and tender contractors directly for single flasks or full class quantities.
Can the flask be heated directly?
The glass is listed as heat resistant. Heat it in a mantle, water bath or over gauze, fill it no more than about half full, and let it cool before washing.
Related Distillation Equipment
A round-bottom flask becomes a working distillation or reflux unit only with a condenser, a heat source and firm support. The four Chemistry Lab items below supply those parts and a smaller flask for lower volumes, so the whole assembly can go on one enquiry.
- Round Bottom Jars (Spherical Balloons) 250ml — smaller round-bottom flask for lower volumes.
- Straight Cooler (Condenser) — condenses vapour in distillation or reflux.
- Flask Electric Heater — heats the flask without an open flame.
- Laboratory Stand — supports the clamped flask and condenser.
