Grav Labs - Helix Tube - Round Bottom 7mm Scientific Glass Tube
Get twice the Helix smoke cooling power in this voluminous round bottom Helix Tube from Grav Labs! Made in the USA (Austin, Texas) using 7mm-thick, laboratory-grade borosilicate glass, this set-up features the Helix funnel-shaped Venturi Chamber body on the tube and another on the included Helix Pre-Mix Chamber precooler. Micro-holes at the shoulders of the body are angled in the same direction to create a swirling vortex of cooler, smoother smoke that's fascinating to watch and easier on your throat and lungs! This tube comes with an 18.8mm > 14.5mm diffuser downstem and a 14.5mm one-hitter bowl. The acrylic joint clamp is NOT included.
A color Grav Labs decal is applied on the tube and precooler in black, blue, red, green, or etched, as available.
