Water-free reflux condenser for common laboratory chemistry applications
The Findenser Air Condenser is a water-free alternative to traditional water-cooled reflux condensers. Designed for solvent volumes from 5 mL to 1 L, it replaces water-cooled condensers in more than 95% of common chemistry applications while eliminating the need for a continuous water supply.
By removing running water from the reflux process, Findenser helps reduce water consumption, lowers water purchase and disposal costs, and eliminates the risk of laboratory flooding associated with water-cooled condensers. It also supports laboratory sustainability and water reduction initiatives.
How Findenser works
The patented Findenser design combines an internal glass condenser with an external finned aluminum jacket. A small amount of water is permanently sealed between the glass condenser and the aluminum jacket, creating a sealed assembly that maximizes thermal conductivity and heat transfer.
The internal glass condenser provides a larger surface area than a conventional air condenser, while the finned aluminum jacket further increases the external cooling surface. Together, these features provide efficient air cooling without the need for running water.
Design features
The Findenser Air Condenser is designed for straightforward integration into existing laboratory setups.
Key design features include:
- Patented sealed construction with encapsulated thermofluid for efficient heat transfer
- Finned aluminum jacket for high-performance air cooling
- Chemically resistant anodized surface
- Standard ground glass joints compatible with tapered glass sockets
- Compatible with conventional laboratory clamps
- Optional clamping kits and PTFE adapters available
- Contoured anti-roll design that helps prevent rolling and protects the aluminum fins when the condenser is not in use
