Round Bottom Flask, Wide Neck
Product Code : LSK-LF-10429
Round Bottom Flask, Wide Neck (SKU LSK-LF-10429) is a spherical glass flask with a broad 50 mm neck and a beaded rim, used in laboratories for mixing, heating and boiling chemicals. Chemistry teachers and lab technicians choose the wide-neck form when solids or a thermometer must pass through the mouth easily. Science Lab Supplies sends it out from Ambala, India, quoting schools, colleges, training institutes, tender contractors and distributors directly as a laboratory glassware supplier in India.
Specifications
The round body spreads heat evenly over its surface, which is why this shape is preferred for boiling and prolonged heating. The 50 mm neck makes filling and cleaning simple, and the beaded rim reinforces the mouth against chipping. The listed body diameter is 105 mm and the overall height 168 mm.

Applications and Experiments for the Wide Neck Round Bottom Flask
A round bottom flask is the standard vessel for heating liquids evenly, and the wide neck makes it easier to add solids, fit a bored stopper with a thermometer and clean the inside after a reaction. It suits senior-school chemistry practicals, B.Sc. chemistry laboratories and pharmacy or polytechnic labs that boil solutions routinely.
- Class 11–12 chemistry: heating and boiling solutions in preparation experiments.
- B.Sc. chemistry practicals: warming reaction mixtures on a heating mantle or water bath.
- Dissolving solids and mixing reagents where a wide opening makes charging easier.
The rounded base cannot stand alone, so hold the flask in a clamp or on a cork ring, heat gradually and add anti-bumping granules before boiling.
Standard Scope of Supply
The Round Bottom Flask, Wide Neck is supplied as a single unit as described above; any optional accessories are listed on the quotation. Clamps, cork rings, stoppers and heating equipment are separate items that can be quoted alongside the flask if your laboratory needs them.
Packing, MOQ and Lead Time
Quotations can be prepared for a single flask or for a full chemistry laboratory glassware order, and each one sets out the packing, delivery time and price for the quantity you request. Other flasks and glassware can be added to the same quotation when you are equipping a whole bench.
Holding an Importer-Exporter Code as a registered exporter, Science Lab Supplies can ship to buyers in Kenya, Ghana, Ethiopia, Tanzania, Uganda and the UAE. To enquire, add the flask to the enquiry cart, write in through the contact page, or see the lab tender page for institutional purchases.
