Some views oven pumping today. Usually the tubes are cleaned by electrically bombarding (scrubbing) the walls clean however the coils in the back are prone to self destructing on the bombarder so they need to get heated in an oven. This time I came prepared with the manifold and the #kiln on wheels. The front two rainbow doodles are filled with #helium and the back coils are Argon Hg. The green flexible #viton rubber vacuum hose is so convenient!
