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 comes in 100 mL to 2000 mL with 24/29 or 29/32 joints and suits school, college and research chemistry practicals. Science Lab Supplies quotes the flask from Ambala, India, and can deliver class sets or tender lots to schools, colleges, tender contractors and distributors.
Specifications
Joint sizes and dimensions for every capacity of the stoppered conical flask are set out in the table. In short, each size has a ground joint that takes its hollow glass stopper; the 100 mL and 500 mL flasks come with either a 24/29 or a 29/32 joint, while the 250, 1000 and 2000 mL flasks carry 29/32.

Applications and Experiments for the Conical Flask
The sloping sides let a solution be swirled without splashing, and the stopper keeps volatile contents closed between steps. That makes the stoppered flask core school chemistry lab equipment in India, and it suits college analytical benches and research labs just as well.
- Class 11–12 chemistry: acid-base and redox titrations in volumetric analysis, with the burette held in a Burette Stand With Fisher Clamp.
- B.Sc. analytical chemistry: titrations where the flask must be stoppered and shaken, with titrant delivered drop by drop from a Borosilicate Burette with Rota Stopcock.
- Preparing standard solutions with the stopper in place to limit evaporation, before transfer to Reagent Bottles Narrow-Mouth for storage.
- Research and quality labs: mixing and short-term holding 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 joints exist for one 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. Mention the capacity and joint of each flask when you write through the contact page; alternatively, build the order in the enquiry cart or check the lab tender page for tender procedures.
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, so the contents can be shaken, swirled or left standing without spilling or losing volatile components.
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, while the 250, 1000 and 2000 mL sizes use the 29/32 joint only.
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?
It is supplied by Science Lab Supplies in Ambala, which can quote this conical flask for schools in India as well as for colleges, in quantities from a few replacement flasks to complete titration benches and tender schedules.
