Single-Pass Cooling
Single-pass cooling is the term used to describe a process that uses water to cool something once. This is in contrast to closed-loop or recirculating systems, which reuse water continuously. Single-pass cooling can be found in equipment such as autoclaves and ice makers. It is also commonly used to cool reactions in chemistry.
Single-pass cooling is not only wasteful, but, as many labs know, it can be a safety hazard as well. Eliminating this from your workflow can save hundreds of thousands of gallons of water each year and prevent the risk of flooding. Instead of running water continuously to cool a reaction try one of these ideas instead:
The first two work great for reactions that are less than 1L; the third is typically the best choice for larger reactions.

Instead of running water continuously to cool a reaction try one of these ideas instead:
- An ice bucket + a fish pump to create a recirculating water bath
- An air-cooled condenser
