Standing at 7" tall it is made on a 44mm tubing. it has a showerhead down stem which can be removed easily for cleaning. the base comes with a 14mm funnel bowl to work with any STAX percolator or mouthpiece. this product works best with only about 2" of water.
It's pretty straightforward, what you'll need is some ISO, water, rubber bungs, and a wire brush. Remove the down stem and bowl so that you can scrub around it and get the hard to reach areas. then let the water and ISO soak in the beaker base for a few minutes. After that you can empty the solution and use it for the bowl and down stem. After, let everything dry and you are left with a nice clean glass piece.
