Applications and Experiments for the Erlenmeyer Flask
The Erlenmeyer flask holds a solution while it is swirled or titrated, and its narrow neck reduces splashing. With the stopper in place it can also keep a prepared solution closed between lessons. It suits CBSE/NCERT Class 11–12 volumetric analysis and B.Sc. chemistry practicals.
- Class 11–12 titrations: acid–base and redox titrations with a Burette for Acids clamped above the flask.
- Measuring the aliquot: transferring a fixed volume of solution into the flask with Graduated Pipettes.
- Rinsing the walls during a titration with distilled water from a Plastic Washing Bottle (Pisetta).
- B.Sc. practicals: preparing and keeping reagents under a ground glass stopper.
Standard Scope of Supply
Each unit is one glass conical flask with its ground glass stopper, in the capacity you choose from 25 ml to 500 ml. Tell us how many of each size you need; burettes, funnels and other titration glassware can be added to the same quotation as separate lines.
Packing, MOQ and Lead Time
Quotations can be prepared for a handful of flasks or for a mixed set of sizes for every bench in a titration lab. Each one gives the packing, delivery time and price for the sizes and quantities requested, and a burette and funnel can be added to build a titration apparatus set.
Because it holds an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Malaysia, Peru, Egypt, Iraq, Nigeria and Kenya. For a size-by-size price, list the capacities on the contact page, drop the flasks into the enquiry cart with other glassware, or check the lab tender page for a school or college tender.
Frequently Asked Questions
Which capacities are available?
The flask is offered in 25 ml, 50 ml, 100 ml, 250 ml and 500 ml. The middle sizes suit routine titrations, while the 25 ml and 50 ml flasks can serve small-volume or micro-scale work.
Are the graduations accurate enough for measuring?
They give an approximate volume only. For exact volumes, measure with a pipette, burette or volumetric flask and use the conical flask for mixing and titrating.
What type of stopper does it have?
A fixed ground glass stopper, which seals the neck so a prepared solution can be kept closed between practicals, while the beaded rim helps when the contents are poured out.
Who supplies the Conical Flask (Erlenmeyer) with Stopper?
Quotations for this flask are issued by Science Lab Supplies in Ambala, India, together with the rest of its laboratory glassware, and can cover one capacity or a full titration-lab quantity in several sizes.
