The Grav Labs Bubbler Review

The Grav Labs bubbler is a clear glass hand pipe that has proven popular for many reasons. At 32 millimeters, it is handy to take with you, slipping discreetly in a pocket or a purse. Among glass bubblers in this category, the Grav Labs bubbler is one of our all-time favorites for many reasons, not the least of which is that this is a finely crafted, truly cool device that works perfectly.

The Grav Labs Bubbler

Based in Austin, Texas, Grav Labs is a highly respected name in glass manufacturing. The company is one of the industry’s venerable names, having built its reputation on the manufacture of scientific glass supplies sold under various brands.

The Grav Labs bubbler is made of premium grade borosilicate glass, which is more resistant to thermal stress than other types of glass. For obvious reasons, bubblers should be able to withstand some heat, and on this aspect, this Grav Labs hand pipe and bubbler exceeds expectations. It has a built-in bowl that will hold the dried herb, and it features the X-cut down stem for the water. This part of the bubbler is designed with a pair of glass feet to keep the appliance stable on a flat surface when you absolutely have to put it down. The comfortable mouthpiece is made of the same clear glass.

The Grav Labs decal is available in black, red, green, blue or a sandblasted or frosted logo, giving you an opportunity to personalize your bubbler.

To use the Grav Labs bubbler, put water in the down stem through the opening in the bowl. The amount of water affects the output that you get, so it is up to you to experiment with this part. Remember that bubbling water acts as a filter, so less water means bigger and more powerful hits while more water in the down stem results in slower but smoother tokes. Pack the dried herbs into the bowl section, cover the carb hole and light up to get some action out of your bubbler. It is not necessary to dry the bowl before packing the medicinal herbs in it. To control your toke, cover or uncover the carb hole provided at the side of the bowl.

At a diameter of 32 millimeters, this bubbler is the ideal size for a single user although you could probably share a few tokes with a buddy. We found it very convenient to take this along anywhere, and preparing to use it took only a few simple steps. Indeed, we managed some hits while on the go, and each time the hits were smooth and great tasting, all proof that this water filtered bubbler is a well-engineered glass piece.

We also like that it has this really cool design that evokes fancy science lab rather than a basement contraption. The hammer-like design makes it easy to handle because the last thing you want is to fumble with an awkward apparatus when you prepare to take your medicinal herbs. The Grav Labs bubbler is lightweight, yet we can attest to its durability. Borosilicate glass is used for scientific supplies because it can take a lot of physical and chemical stress yet remain functional for a long period. Expect your Grav Labs bubbler to be around for a long time.

So in terms of functionality, classy design and ease of use, the Grav Labs bubbler is A-rated. On top of that, this bubbler falls in the highly affordable category so that you are likely to want more than one piece after you try it.

As much as we liked this bubbler, we did have some issues with it

  • The resin showed through the clear glass, affecting our enjoyment at times.

Here Are Some Tips To Clean The Grav Labs Bubbler

Resin build-up inside the bubbler can be cleaned in one of two ways: water and soap or rubbing alcohol and salt.

Put water in a pot that is large enough to hold the bubbler. Put the bubbler in the pot, making sure that it is fully submerged. Bring the water to a slow boil, making sure that the pipe step is bubble-free and filled with water. Turn off the heat when most of the resin on the pipe appears to have been washed out. Allow to cool for a few minutes before picking up the bubbler with a pair of tongs. Shake vigorously to dislodge leftover resin. Discard the heated water and refill the pot with lukewarm water. Add detergent and place the bubbler in the soapy solution. Using pipe cleaners or Q-tips, reach into the tube to scrub off remaining resin. Rinse and allow to air dry.

As an alternative to the detergent solution, fill a quart bag with rubbing alcohol and some salt. Sprinkle salt into the interior of the pipe and drop the bubbler in the plastic bag with alcohol. Swish around for a few minutes then retrieve the bubbler for drying and discard the salt and alcohol mixture. If there is any remaining resin, use pipe cleaners to reach in and clean out.


The Grav Labs bubbler is an impressive glass pipe for use with dried herbs. It is made of borosilicate glass, which is the preferred type of glass in laboratories because of its higher resistance to chemical and physical stress. This bubbler is small, measuring only 3.5 inches with its pipe diameter at 32 millimeters. As such, it is convenient and circumspect to carry around.
