Round Bottom Flask, Wide Neck (Product Code: SLE/GFL/14) combines the even-heating spherical body of a round bottom flask with a broad opening that makes it easy to add solids, drop in a stirring bar and reach inside for cleaning. Made in graduated borosilicate glass, it is used for heating reaction mixtures, dissolving solids and recrystallising products in college and research chemistry laboratories. The flask is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of the laboratory glassware it supplies to institutions in India and international markets.

The wide mouth is chosen when a procedure involves solids or thick mixtures — weighing a powdered reagent straight into the flask, scraping out crystals after recrystallisation, or working with viscous liquids that would cling to a narrow neck. Placed in a heating mantle with a built-in magnetic stirrer, the flask keeps its contents moving while they are heated, and the broad opening leaves room for a stopper that carries both a thermometer and a condenser adapter.
Support the curved base in the mantle or with a clamp on the neck, since the flask cannot stand unaided. Choose a mantle that matches the flask capacity so the glass is in full contact with the heating surface. After use, the wide neck lets a brush reach the whole interior, which makes this flask easier to return to a clean state than its narrow-neck counterpart.

Heating, stirring and support items that suit a wide-neck round bottom flask:
All flask types are grouped in the Glassware Flasks category.
When should I choose the wide neck over the narrow neck?
Choose it when you add or remove solids, use a stirring bar, or need thorough cleaning between runs. For distillation where a small stopper and minimal evaporation matter, the narrow-neck flask is usually preferred.
Can I use a magnetic stirring bar in it?
Yes. The wide opening makes it easy to drop a stirring bar in and retrieve it afterwards with a magnetic retriever.
Which capacities are available?
50 ml, 100 ml, 250 ml, 500 ml and 1000 ml.
Is the neck fitted with a ground-glass joint?
A joint is not specified for this flask. Contact us if your set-up needs a particular joint size.
What warranty is offered?
Warranty terms are given with each quotation; ask us for the current terms when you enquire.
What should I include in an enquiry?
The capacities, quantity per size, delivery location and whether you need matching mantles or stoppers, so we can quote everything together.
