Round Bottom Jars (Spherical Balloons) 100ml (SKU SCL-CL-11504) is a 100 ml round-bottom flask: a spherical transparent glass body with a long neck, made for heating liquids evenly and for assembling reflux and distillation set-ups. Chemistry students meet it in senior secondary practicals and in college organic chemistry. It is supplied by Science Lab Supplies from Ambala, India, to schools, colleges, training institutes, tender contractors and distributors, together with other laboratory glassware.
Specifications
The vessel has a spherical body and round bottom with a long mouth (neck) and a 100 ml capacity. It is made of transparent glass listed as chemical resistant and heat resistant. The rounded shape spreads heat evenly, and the long neck takes a stopper, condenser or adapter.

Applications and Experiments for the Round Bottom Flask 100 ml
A 100 ml round-bottom flask holds small reaction mixtures that must be boiled, refluxed or distilled without hot spots. It is used in Class 11–12 chemistry demonstrations, B.Sc. organic chemistry preparations, and in pharmacy and chemical laboratory courses where small-scale synthesis is taught.
- Class 11–12 chemistry: simple distillation and heating of small liquid volumes.
- B.Sc. organic chemistry: refluxing small reaction mixtures with a condenser.
- Pharmacy and chemistry diplomas: small-scale preparations and solvent recovery.
- Demonstrations: gas solubility experiments such as the fountain experiment.
A round-bottom flask cannot stand on its own; hold it in a clamp or rest it on a cork ring, and never heat it when it is sealed.
Standard Scope of Supply
The Round Bottom Jars (Spherical Balloons) 100ml is supplied as a single glass flask as described above. Stoppers, condensers, clamps and heating sources are separate items and can be added to the same quotation.
Packing, MOQ and Lead Time
You may request prices for one flask, a class set or a full laboratory quantity; every quotation lists the packing, delivery time and price for the number you specify. Condensers, adapters and stoppers can be included to make up complete distillation kits.

Frequently Asked Questions
Is this the same as a round-bottom flask?
Yes. The listing name uses "round bottom jar" and "spherical balloon", but the item is a 100 ml round-bottom flask with a spherical body and long neck.
What is a 100 ml round-bottom flask used for?
It is used to boil, reflux or distil small volumes of liquid evenly, especially in organic preparations where the flask is joined to a condenser.
How should the flask be supported while heating?
Clamp it by the neck to a stand or rest it on a cork ring, heat it through a water bath or gauze, and keep the system open to the air.
Who supplies the Round Bottom Jars (Spherical Balloons) 100ml?
Science Lab Supplies supplies it from Ambala, India, quoting schools, colleges and tender contractors for single flasks or laboratory quantities with matching accessories.
Related Distillation and Heating Glassware
A round-bottom flask is normally used as part of an assembly with a condenser and a stopper, or swapped for a larger flask as volumes grow. These four Chemistry Lab items build on the 100 ml flask for distillation and reflux work and can all be quoted together.
- Round Bottom Jars (Spherical Balloons) 250ml — larger round-bottom flask for bigger batches.
- Distillation Pot with Side Funnel 250ml — flask with side pipe for simple distillation.
- Straight Cooler (Condenser) — condenses vapour during distillation or reflux.
