Distillation Flask
Product Code : LSK-LF-10423
Distillation Flask (SKU LSK-LF-10423) is a flask with a side arm, designed to separate liquid mixtures by distillation. Vapour rises up the neck and leaves through the side arm to a condenser. It comes in 100, 125, 250 and 500 mL sizes and suits school demonstrations and college practicals. Schools, colleges, training institutes, tender contractors and distributors can buy it from Science Lab Supplies, with quotation and dispatch handled in Ambala, India.
Specifications
Dimensions of all four distillation flask sizes, including the side arm, are given row by row below. In short, the 100 and 125 mL flasks have a 7 mm side arm and the 250 and 500 mL flasks a 9 mm side arm, with arm length rising from 100 to 130 and height from 215 mm to 240 mm.

Applications and Experiments for the Distillation Flask
Heating the mixture in the flask boils off the more volatile liquid first; its vapour passes through the side arm, condenses and is collected separately. The flask is a basic part of any laboratory distillation apparatus in India, from school demonstrations to college purification work.
- Class 9 science: separating two miscible liquids with different boiling points by simple distillation.
- Class 11–12 chemistry: purification of liquids and preparing distilled water, with the flask heated over a burner or an Electric Hot Plate.
- B.Sc. chemistry practicals: purifying organic liquids and noting the boiling range.
Clamp the neck on a Retort Stand with Boss Head and Clamp, add boiling chips before heating, never distil to dryness, and fit the thermometer through one of the Rubber Stoppers of Various Diameters with Holes, with its bulb level with the side arm.
Standard Scope of Supply
The Distillation Flask is supplied as a single flask with its side arm, in the capacity ordered. A condenser, thermometer, stopper, receiver and stand can be added to the quotation to complete the distillation set, so every part of the train is priced and packed together.
Packing, MOQ and Lead Time
One flask for a teacher demonstration or a full set for a practical batch can both be quoted, with packing, delivery time and price shown for the number you request. This school chemistry lab equipment in India can share a quotation with condensers and receivers.
Science Lab Supplies, a registered exporter with an Importer-Exporter Code, can ship to buyers in Vietnam, Malaysia, Peru, Egypt, Iraq and Nigeria. Quote requests for one size or all four can start in the enquiry cart or on the contact page, and schools buying by tender can follow the steps on the lab tender page.
Frequently Asked Questions
What is a distillation flask used for?
It holds a liquid mixture while it is heated so the more volatile part boils off, leaves through the side arm to a condenser and is collected separately as a purer liquid.
Which sizes are available?
Four capacities are offered: 100 mL and 125 mL with a 7 mm side arm, and 250 mL and 500 mL with a 9 mm side arm, each with its own height and body diameter.
Can a condenser be quoted with it?
Yes. A Liebig condenser, thermometer, stopper and receiver can be quoted together with the flask, so the complete distillation set is priced on one document and packed in one consignment.
Who supplies this distillation flask?
School and college buyers receive it through Science Lab Supplies, which quotes each of the four sizes from Ambala, India and handles orders from a single flask up to a tender lot.
