Quick answer: A Reflux Assembly combines a round-bottom flask with a condenser via a vacuum-tight ground glass joint, allowing a reaction to be heated and boiled continuously while the condenser returns evaporated solvent back into the flask — a standard setup for organic synthesis experiments. This listing does not currently show a published price on stemaids.com — contact STEMAids directly for an indicative quotation.
The Reflux Assembly is built around ground glass joints and a condenser designed to return evaporating vapour back into the reaction flask as liquid, allowing a mixture to be boiled continuously for an extended period without losing solvent. This reflux technique is a foundational method taught in organic chemistry practical courses for reactions that need sustained heating to reach completion. The ground glass joints provide a tight, reusable seal appropriate for repeated classroom and research use, and the modular design allows the assembly to be paired with different flask sizes depending on the scale of the experiment.

Applications
- Organic synthesis reactions requiring continuous reflux heating
- Teaching standard reflux technique in college organic chemistry laboratories
- Research-level reactions with volatile or flammable solvents requiring vapour return
- Extraction and reaction procedures that run over extended heating periods
Care & Maintenance
- Apply a thin film of appropriate joint grease to ground glass joints to prevent sticking, unless using PTFE sleeves
- Inspect joints for chips before each use, since a damaged joint can compromise the vacuum-tight seal
- Clean promptly after use to prevent residue from bonding to the ground glass surface

Frequently Asked Questions
What is a reflux assembly used for?
It allows a reaction mixture to be boiled continuously for an extended time without losing solvent, since the condenser returns evaporated vapour back into the flask as liquid — commonly used for organic synthesis reactions that need sustained heating.
What size ground glass joint does this assembly use?
Exact joint size has not been independently verified for this listing — confirm compatibility with your existing glassware with STEMAids before ordering.
Is this suitable for a college organic chemistry lab?
Yes — reflux setups are a standard part of organic chemistry practical coursework, and this assembly is designed for that kind of teaching and research use.
Does the price include the flask, or just the condenser and joint?
This listing does not currently show a published price on stemaids.com — contact STEMAids directly for an indicative quotation covering the full assembly.
Can this be used with different flask sizes?
The modular ground glass joint design is intended to allow pairing with different flask sizes; confirm exact compatible sizes with STEMAids before ordering.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
