The Red Eye Tek 12-inch Synth Series Harmony is a beaker built in thick 7mm borosilicate glass, so it has real weight and stands up to daily use. The classic beaker base holds plenty of water for good filtration and keeps the piece stable. It comes with a matching downstem and bowl, ready to use, and the clean Synth Series lines give it a modern look. At 12 inches it's an easy everyday size. A sturdy, well-built daily beaker for someone who wants thicker glass and a simple, reliable design.
