(CMTO) TAG - 20" Double Super Slit Matrix Beaker 55x5MM (18MM Female)
The 20 inch Double Super Slit Matrix Beaker pairs the stability of a beaker base with two full stages of percolation for a genuinely soft, twice-filtered draw. Air enters through a fixed stem, then hits the first Super Slit matrix, which shreds the pull across dozens of fine slits into a dense column of tiny bubbles. That column feeds a showerhead stage that diffuses again and spreads contact across the water's surface, so by the time a draw reaches the neck it has been cooled and broken up twice over. Two stages add some drag over a single open perc, which is the fair trade for this much diffusion.
The tube is 55MM in diameter with 5MM walls, heavy-wall borosilicate that handles daily use and the knocks a tall beaker invites. The wide beaker base drops the center of gravity and holds a larger water volume, so it clears well and stays steady on the table. The 18MM female joint runs the included matching glass slide, and the sandblasted logo is permanent, so it won't fade with repeated cleaning.
This is a CMTO (custom made to order) piece, not ready to ship. Lead time can run up to roughly 12 months. Expect slight height variance. Avoid thermal shock and let the glass reach room temperature before cleaning.
