Today I’m selling my JM Flow Sci mini beaker tube. It has a 38mm neck with a flared mouthpiece which I like. It has a gridded stem to gridded ball Perc that has incredible function. This is one of my favorite pieces in my collection. It stands just over 8” and has a 14mm male joint. Has a small water mark in the neck but a good soak should take care of that. I can include a 14mm female joint slide for free if you decide to purchase.
