Concentrate bubblers are the same as a bubbler pipe, but are can be used for concentrate oils. They also use water and essentially work the same as any other bubbler. Instead of featuring a female joint, many concentrate bubblers have male joints, often referred to as "Direct Inject". Concentrate bubblers are often equipped with a glass nail and oil dome designed for dabbing. Most concentrate bubblers are small and have a bent neck. A small piece with little diffusion will give you the best flavors from your vapor. If this is your first time shopping for a concentrate bubbler, check out the Black Sheep Sherlock Bubbler. It comes equipped with a domeless quartz nail for only $60! If your ready to upgrade and want something heady check out the Bird Rigs by RJ Glass. There's lots to choose from, so take your time and dab on!
