The 18" Double Tree Perc Beaker is as visually impressive as it is highly-functional. This scientific glass bong includes two stacked 10-arm, reinforced tree percs at the center of the neck creating unbeatable smoke percolation and water filtration. The design of this beaker makes it an ideal pick for those looking to achieve the biggest and smoothest hits possible. It features both a three-prong ice pinch and splash guard above the twin tree percs giving you the option to fill the top half of the chamber with ice for an even smoother smoking experience as well as preventing water from reaching you the mouthpiece.

Included for free with this item is a 14mm Round Bowl w/ Ring for cool handling as well as a 4", 18mm to 14mm Diffused Downstem for increased filtration and easy cleaning. There are also a number of additional upgrades and accessories available which can be added to your purchase using the drop-down menus. These include various styles of bowl pieces, nails for dabbing concentrates and downstems. More information about converting between "dry" and "concentrate" use can be found in our Blog and FAQ page.

Replacement items and other additional accessories can be found on our Accessories page. Information about how to clean and maintain your glass piece is located our Blog and FAQ

    Bought this about 6 months ago, and it's been everything I've wanted. Thick glass, easy to clean, smooth and milky hits. Absolutely recommend!

    18” double tree perc beaker bong

    Posted by Vivien on Jan 13th 2021

    I bought this to exactly replace the best piece I’ve ever had, and to be quite honest I’m now thinking the kid I bought it from got it from here because it’s AN EXACT copy. I am completely satisfied! And the customer service is incredible. I emailed them a week ago when this was out of stock asking when it would be back, within a few hours got a reply and well, I now have my bong. :)

    Amazing Piece

    Posted by Frosty on Jan 1st 2021

    I’ve been using this piece for my nightly smoke over the past 3 months, and it’s just great. The percs filter the smoke smoothly and it hits like a dream with a few ice cubes. The glass is incredibly thick and well done for this price point, it’s survived multiple falls from table and shoulder height with not so much as a crack / scratch.

    Worth it!

    Posted by Gab on Sep 7th 2020

    I was a little skeptical shopping here and in getting such a good deal on this piece.. but it is exactly what you wanted it to be! Hits great and may not be the thickest glass but definitely not the cheapest/thinnest ive seen before either! Treat it nicely and it'll be worth the money! Shipping was super quick as well, easy process, 10/10 recommend.

    Very nice, high quality item. Glass joints have been flame polished and are very solid. Very easy to see it is a handmade item with great attention to detail. I inspected the entire surface with a magnifier and found absolutely no flaws. I would definitely recommend Glassics. Water moves evenly with a consistent smoke diffusion. Over all, just a great piece.

    The best scientific glass

    Posted by Josh on Jul 5th 2020

    Recently had a friend break my old school PHX clear glass pipe and I was super sad. I started scouring the web for something identical. It took me about a month and finally came upon this website and this particular model which was exactly what I was looking for at an amazing price. My only alternative was a Roor at $600 so this made my day. Product arrived unharmed and in amazing packaging with some extras! I was a little worried about the product being lower quality but I can assure you that it is superior quality and will last me a long time. Now I just need to order some extras that I forgot to get!
