## TL;DR

This paper introduces a water-saving condenser for chemical synthesis that performs as well as traditional water-jacketed condensers.

## Contribution

A novel waterless condenser design that is efficient and suitable for various solvents, including water.

## Key findings

- The condenser performs comparably to conventional water-jacketed glass condensers across many organic solvents.
- A Teflon cap with a safety valve enhances the condenser's effectiveness.
- The smallest condenser is well-suited for reactions using water as a solvent.

## Abstract

We describe the design of an efficient waterless condenser
for
use in chemical synthesis, which exists in two different sizes. This
laboratory equipment displays performances comparable to those of
conventional water-jacketed glass condensers across a broad range
of organic solvents. It is most effective when fitted with a Teflon
cap containing a safety valve. The condenser with the smallest cross-section
is particularly suitable for reactions using water as a solvent, despite
its lower vapor density than air.
