High functioning science glass beaker from Zob Glass out of California. “Instrumentum Percolatus” is their moniker as they make science glass with insane function through elaborate percolation. This is their micro straight tube with UFO perc – which is a tuned dome perc. Up top you have a splash guard perc and a small ice chamber. At 15.5 inches this is a light, slender, easy to handle beaker bong that shreds with big function in a smaller piece! Filling the top with crushed or snowcone ice really cools things down, and with this level of percolation it’s a really smooth pull. 14mm high quality snap bowl comes with. 5mm tubing makes for a solid piece. This bong has green and black Zob labels. Zob Glass is proud to be American glass made in California, and here at Columbia River Glass we only support American glass!
