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 evenly, which suits distillation and reflux set-ups in school and college chemistry. These flasks reach schools, colleges, distributors and contractors through Science Lab Supplies, which quotes and dispatches them from Ambala, India.
Specifications
Every specification of the 500 ml long-neck spherical flask is laid out row by row below. In short, it is a transparent glass sphere with a round bottom and a long mouth, or neck, that takes a stopper, adapter or thermometer, and the glass is heat resistant and chemical resistant for heating over a mantle or gauze.

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 a teaching distillation or reflux assembly, from simple water purification to organic preparations.
- NCERT Class 9 science: separating miscible liquids or purifying water by distillation, with the flask held on a Laboratory Stand.
- CBSE Class 11 and 12 chemistry: simple distillation and the preparation of organic compounds, using Rubber Stoppers of Various Diameters with Holes for the thermometer and delivery tube.
- B.Sc. organic chemistry: heating reaction mixtures under reflux with a condenser, joined where needed by an Adapter (Alunge).
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 can be quoted with the flasks to complete an assembly.
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. To cost a distillation bench, describe it on the contact page, place flasks and condensers in the enquiry cart, or see how bids work 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?
Science Lab Supplies in Ambala, India prices them per flask or in class quantities, and the same quotation can add condensers and heaters. Schools, colleges, resellers and tender contractors can all request one.
Can the flask be heated directly?
The glass is 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.
