Conical Flask
Product Code : LSK-LF-10421
Conical Flask (SKU LSK-LF-10421) is an Erlenmeyer-type flask with a ground-glass joint at the neck, supplied with a hollow glass stopper so contents can be sealed during mixing, titration or storage. It is listed from 100 mL to 2000 mL with 24/29 or 29/32 joints. School, college and research chemistry labs rely on it daily. Buyers such as schools, colleges, tender contractors and distributors obtain it through Science Lab Supplies, which supplies it from Ambala, India.
Specifications
Each size has a ground joint that takes the matching hollow glass stopper. The 100 mL and 500 mL flasks are available with either a 24/29 or a 29/32 joint, while the 250, 1000 and 2000 mL flasks carry a 29/32 joint. Dimensions per size are shown below.

Applications and Experiments for the Conical Flask
The sloping sides let a solution be swirled without splashing, and the stopper keeps volatile or air-sensitive contents closed between steps. That makes the stoppered flask a core item of school chemistry lab equipment in India and of college analytical benches.
- Class 11–12 chemistry: acid-base and redox titrations in volumetric analysis practicals.
- B.Sc. analytical chemistry: titrations where the flask must be stoppered and shaken during the determination.
- Preparing and holding standard solutions and reagents with the stopper in place to limit evaporation.
- Research and quality labs: mixing and short-term storage of samples.
Standard Scope of Supply
Each Conical Flask is supplied with its hollow glass stopper, in the capacity and joint size you order. Where two joint sizes are listed for a capacity (100 mL and 500 mL), state 24/29 or 29/32 in your enquiry so the quotation matches your existing stoppers and adapters.
Packing, MOQ and Lead Time
Orders range from a handful of flasks to a titration apparatus set for every student bench, and each quotation gives packing, delivery time and price for the quantity you name. Burettes, pipettes and other flasks can be priced on the same document.
Science Lab Supplies holds an Importer-Exporter Code as a registered exporter, which means it can ship to buyers in Qatar, Sri Lanka, Vietnam, Malaysia, Peru and Egypt. Put your list in the enquiry cart, send a note through the contact page, or use the lab tender page for tender enquiries.
Frequently Asked Questions
Does the flask come with a stopper?
Yes. Every flask is supplied with a hollow glass stopper that fits its ground joint.
What capacities and joint sizes are available?
Capacities are 100, 250, 500, 1000 and 2000 mL. The 100 and 500 mL sizes come with a 24/29 or 29/32 joint; the other sizes use 29/32.
Why choose a ground-joint conical flask over a plain one?
The ground joint and stopper give a close seal, so contents can be shaken or stored without loss, and the neck can also take other ground-joint fittings of the same size.
Who supplies the Conical Flask?
Science Lab Supplies supplies it from Ambala, India, for school orders, college laboratories and tender quantities.
