Adapters (Alunge)
Adapters (Alunge) (Product Code: SCI-110/029) are clear glass adapters used to connect a condenser to the receiving flask in distillation set-ups in school and college chemistry laboratories. Students and laboratory assistants use them to guide distillate neatly into the receiver; each adapter is 150 mm long and made of fireproof glass pipe that is heat and chemical resistant. This chemistry lab glassware is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

What Is an Alunge Adapter Used For?
In a simple distillation, an alunge (also spelled allonge) adapter fits on the lower end of the condenser and carries the condensed liquid down into the receiving flask. This reduces splashing and vapour loss at the outlet, and the clear glass lets students watch the drops of distillate as they form. The same adapter is useful in fractional and steam distillation practicals wherever a condenser outlet must be led into a receiver.
When assembling distillation apparatus, support the condenser with a clamp so that the adapter carries no load, and join the parts without forcing them. Although the glass is heat resistant, let the adapter cool before washing it and avoid sudden temperature changes; rinse it after each run so that residues do not build up.
What to Specify When Ordering
- The number of adapters, including spares for breakage in student classes.
- The condenser and flask you will use it with, so we can confirm the connection suits them (only the 150 mm length is listed here).
- Whether the rest of a distillation set, such as the condenser and distillation pot, should be quoted together.
OEM Manufacturer
ScienceLab offers these adapters as their original manufacturer, not as a reseller. Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM and produces them at its own licensed factory at Saha, Ambala, Haryana, India.
Glass parts break from time to time, and buying from the maker keeps replacements simple: send the product code and the manufacturer quotes directly. Schools, colleges, dealers and importers are all supplied factory-direct — see our company profile.
Related Laboratory Equipment
The other parts of a typical distillation train:
- Straight Coolant (Condenser) — the condenser that the adapter attaches to.
- Distillation Pot with Side Tube — the boiling flask at the start of the set-up.
- Liquid Distillation Apparatus — a complete distillation set.
- Conical Flask — a convenient receiver for the distillate.
- Laboratory Thermometers 0-200 deg C — to read the vapour temperature.

Frequently Asked Questions
What are the Adapters (Alunge) used for?
The Adapters (Alunge) connect the outlet of a condenser to a receiving flask during distillation. They lead the condensed liquid into the receiver with less splashing and vapour loss, and the clear glass lets students see the distillate forming.
What size and material are the Adapters (Alunge)?
Each of the Adapters (Alunge) is 150 mm long and made of clear, fireproof glass pipe. The glass is described as both heat resistant and chemical resistant, which suits routine distillation work in teaching laboratories.
Will the alunge adapter fit my existing condenser?
Only the 150 mm length of the Adapters (Alunge) is listed here. Send us the details of your condenser and receiving flask through the contact page, and we will confirm whether the adapter suits them before you order.
How should the glass adapters be cleaned?
Allow the Adapters (Alunge) to cool after use, then rinse them with water and a suitable solvent for the residue, brushing gently if needed. Dry them on a rack and store them where they cannot roll or knock against other glassware.
Who manufactures the Adapters (Alunge)?
ScienceLab, the trading name of Jain Scientific Equipments Pvt Ltd, is the OEM manufacturer of the Adapters (Alunge). They are made at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied directly to institutions, dealers and importers.
Can the Adapters (Alunge) be ordered in bulk or for export?
Yes. ScienceLab supplies the Adapters (Alunge) in bulk to schools, colleges, dealers and importers in India and international markets. Send the product code SCI-110/029, the quantity and the delivery location through the contact page for a quotation.
