Gas Washing Bottles
Gas washing bottles are a type of laboratory glassware designed to introduce a gas to either gas or liquid. The gas washing bottle has a wide variety of chemistry applications, such as infusing one gas into another to produce a desired reaction, or to wash a byproduct from a previous reaction. Oftentimes a fritted glass disc is present to separate particles before introduction.
The key concerns when choosing a gas washing bottle are (a) the size of the reaction vessel, (b) the frit porosity needed, and (c) the joint openings required to connect to the rest of the system.
