The thick-oil glass cartridge.

The QBD-g1 glass body cartridge specializing in easy capping, quick priming, and amazing performance with high viscosity oils. It’s clog resistant by design, and boasts the first cotton free coil in an all glass cartridge.

The first cotton-free cartridge


The innovative coil of the QBD-g1, utilizes ceramic to wick oils, instead of traditional cotton. This leads to better flavor over the lifetime of the cartridge, and less of a chance of burnt coils. Due to silicone high heat conductivity, the chances of dry coils are even lower. This cartridge is also low waste, with it’s oversized gaskets to channel oil into it’s large 2x3mm  intakes.

Clog resistant all glass cartridge

Finally, the QBD-g1 delivers some of the best reliability of any of the glass cartridges. The larger diameter air stem combined with a raised air inlet allows for clog resistant performance. The ceramic element (manufactured by Cerall) is the first to be utilized sans cotton, enclosed in a high temperature silicone gasket. This cartridge is designed to run flooded, and delivers walloping hits with thick materials, like Δ8. Due to the high amounts of silicone in this design, please limit terpene concentration to 6%

The simplest design

Glass body cartridges are the easiest cart on the market to fill and cap. This is due to the all glass cartridges’ unique vial style design. First, filling is as simple as shooting one’s extract against the sidewall.The operator only needs to avoid the center posts. Second, capping speed is unimportant, because there is no space for leaks in the all glass cartridge body.

    I love these carts. They hit hard and seem to work best in the 2.4v-2.8v range. If you’re using a stiff, clear D8 that is only 5% terps, you’re going to be doing a lot of preheating or manually pulsing the firing button in between drags. At 7% terps and/or with a softer D8 these chug along with no problem.

    They’re comparable to metal SPRK carts in performance. They have a much higher capacity and look sexier, but they’re also fragile. (Do not drop them, the center tube will snap.)

    These things rip at only 2.00 volts out of my Yocan UNi pro, and the flavor is great. Larger cloud production than SPRK carts and I don’t have to worry about burning the cotton which means it’s easier to hit for long periods of time, and I can start hitting it before it has had the regular 12-24 hours for the fluid to soak in. The expanded airflow channel and changed coil design also seem to have entirely eliminated the clogging issue seen in the previous version of this cart. Definitely would recommend giving this cartridge a try!
