Round Bottom Pot (Spherical Balloons) 250 ml
Round Bottom Pot (Spherical Balloons) 250 ml (Product Code: SCI-687/074) is a long-necked borosilicate glass round bottom flask used as the boiling vessel in reflux, distillation and synthesis set-ups in chemistry laboratories. With a 250 ml capacity, it gives higher-secondary and undergraduate students a practical working volume for organic preparations while staying easy to clamp and heat evenly. This round bottom flask is manufactured in India by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala.

What Is the 250 ml Round Bottom Flask Used For?
Colleges and senior-secondary schools use the 250 ml round bottom flask for refluxing reaction mixtures, simple and fractional distillation, and preparing organic compounds such as esters in practical syllabi. The spherical shape spreads heat around the liquid, which reduces hot spots when the flask sits in a heating mantle or water bath.
Set-up tips: clamp the flask at the neck, never around the bulb, and fill it to no more than about half its volume for distillation. Add boiling chips before heating. After the experiment, let the glass cool on a cork ring before washing so it is not exposed to sudden temperature changes.
OEM Manufacturer
This flask is an original ScienceLab product. Jain Scientific Equipments Private Limited, the company behind the ScienceLab name, is its OEM (original equipment manufacturer) and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Quotations, supply and after-sales questions therefore come straight from the manufacturer.
Laboratories that lose flasks to breakage during the term can reorder the same code directly — ask us about replacement flasks. See the company profile for more about ScienceLab.
Related Laboratory Equipment
For a complete reflux or distillation assembly around this flask, buyers usually add:
- Heating Mantle 250ml — heats a flask of this capacity evenly
- Straight Coolant (Condenser) — sits above the flask to return or collect condensed vapour
- Universal Clamp — grips the flask neck on a retort stand
- Distillation Pot with Side Tube — an alternative when the distillate must leave through a side arm
