7th Floor Elev8R

The Elev8R by 7th Floor uses ruby balls inside a glass tube as thermal mass. A butane torch heats the balls to operating temperature in about 30-45 seconds. When you draw through the device, air passes over the hot balls and reaches vaporization temperature. The thermal mass holds temperature steady across multiple draws. Compared to electronic ball vapes like the Qaroma, there's no controller warm-up time, but you need a decent torch.

The Elev8R's glass tube is made from borosilicate — the same material used in lab equipment. It handles thermal shock that would shatter regular glass. The balls sit loose inside and can be poured out for cleaning. It fits any 18mm bong or dry piece. With no moving parts or electronics, there's essentially nothing that can break.
