Distillation Flask
Product Code : LSK-LF-10423
Distillation Flask (SKU LSK-LF-10423) is a flask with a side arm on its neck, used in chemistry labs to separate liquid mixtures by distillation. Vapour rises up the neck and leaves through the side arm to a condenser. It is listed in 100, 125, 250 and 500 mL sizes for school and college practicals. Science Lab Supplies provides it from Ambala, India to schools, colleges, training institutes, tender contractors and distributors.
Specifications
Each size has its own body diameter, overall height and side-arm dimensions. The two smaller flasks have a 7 mm side arm and the two larger ones a 9 mm side arm, with the listed arm length rising from 100 to 130 as capacity increases.

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.
- B.Sc. chemistry practicals: purifying organic liquids and noting the boiling range.
Add boiling chips before heating, never distil to dryness, and fit the thermometer bulb level with the side arm to read the vapour temperature correctly.
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 are separate items; any you need can be added to the quotation to complete the distillation set.
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. Get in touch through the contact page, save items to the enquiry cart, or use the lab tender page for tender work.
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.
Which sizes are available?
Four capacities are listed: 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 diameter.
Is a condenser included?
No. The listing covers the flask only; a condenser, thermometer and receiver can be quoted together with it.
Who supplies this distillation flask?
Science Lab Supplies supplies it from Ambala, India, for schools, colleges and tender orders of any size.
