• The F9-3 is used in combination with a flask for distilled water (turnip type). It is a cooler dedicated to distilled water, and since the outlet of steam is well above, water with high purity can be obtained without contamination of droplets, etc. It is also widely used in departments that are sensitive to water, such as biochemistry.
• If you cool it down enough that you can see some steam escaping at the outlet of the water, the release of carbon dioxide also works well.
