Morphology
The constituents 'gas' and 'bottle' clearly signal a container related to gas, but the use of 'washing' here is specialized (meaning scrubbing or bubbling gas through a liquid) rather than the everyday sense of cleaning. A B1 learner who knows the words might guess it is a bottle used with gas, but would likely not predict the exact laboratory procedure or purpose without prior exposure, so the phrase is only partially transparent.
Etymology
Gas washing bottle comes from the idea of 'washing' a gas. In the lab, the gas is bubbled through a liquid in the washing bottle so the liquid takes out dirt or unwanted parts, or adds something to the gas, like water washing clothes. That's why the name means 'a bottle used to clean or treat a gas by bubbling it through a liquid'.
