Product Code : SCL-CL-11504
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. It suits senior secondary chemistry practicals and college organic chemistry. Schools, colleges, training centres, tender firms and dealers can order it with other laboratory glassware from Science Lab Supplies, which ships from Ambala, India.
Specifications
The 100 ml round-bottom flask's details are laid out row by row. In short, the vessel has a spherical body and round bottom with a long mouth (neck), and it is made of transparent glass that is chemical resistant and heat resistant; the rounded shape spreads heat evenly, and the 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 through a Water bath, 7 L.
- B.Sc. organic chemistry: refluxing reaction mixtures with a Straight Cooler (Condenser) fitted to the neck.
- 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 with a clamp on a Laboratory Stand 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 transparent glass flask with a spherical body, round bottom and long neck. 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.

Flask quantities and any matching fittings can be sent through the contact page, saved together in the enquiry cart, or prepared for a bid using the lab tender page.
Frequently Asked Questions
Is this the same as a round-bottom flask?
Yes. Its product name uses "round bottom jar" and "spherical balloon", but the item is a 100 ml round-bottom flask with a spherical body and a long neck, made of transparent glass.
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 prepares the quotation and ships from Ambala, India; single flasks, class sets or full laboratory quantities can be priced with matching stoppers, condensers and clamps.
