What Makes Human Grade Different

Human Grade pieces stand out the moment you pick one up. The glass has weight to it — not the thin, fragile feel of budget imports, but the solid heft of properly made borosilicate. Every bong, rig, and pipe is handcrafted from 100% borosilicate glass, the same heat-resistant, laboratory-grade material used in scientific glassware. Borosilicate resists thermal shock, maintains clarity over time, and won't leach flavors or chemicals into your smoke. For grinders and metal accessories, Human Grade uses premium aluminum with precision-machined teeth and magnetic closures for consistent, reliable performance.

The design philosophy is clean and functional — no unnecessary gimmicks, just thoughtful engineering that makes every session smoother. Pieces feature detachable parts for easy cleaning, smooth interior surfaces that don't trap residue, and bold color accents that give each piece personality without sacrificing performance. Human Grade also follows sustainable glassblowing practices, reducing waste and energy use in production.

The result is a brand that sits in a sweet spot most companies miss: genuinely premium build quality at prices that won't make you hesitate to use your glass every day.

Human Grade Beaker Bongs

Human Grade's beaker bongs are the backbone of their flower lineup — classic designs with the durability and attention to detail that separates them from generic glass. Every beaker features a 14mm female joint with a removable 18mm to 14mm downstem included, an integrated ice catcher for cooler draws, a wide beaker base for stability, and a 14mm flower bowl ready to use out of the box. The clear borosilicate construction showcases your smoke paths while resisting heat and daily wear.

12" Beaker Bong — The full-size flagship. Standing 12 inches tall with a 5.5" downstem, this piece delivers massive, smooth rips with excellent water filtration and ice-cooling capability. The classic beaker shape provides maximum stability and generous water capacity, making it the ideal daily driver for flower smokers who want a desktop piece that performs.

9" Beaker Bong — The midsize option that balances portability with performance. At 9 inches tall with a 5" downstem, it delivers the same smooth, ice-cooled hits as the 12" in a more compact, travel-friendly package. A great choice for smokers who want a versatile piece that works equally well at home or on the go.

6" Mini Beaker Bong — Compact, durable, and budget-friendly. The 6" beaker packs a 4.5" downstem and an ice catcher into the smallest form factor in the lineup, delivering reliable filtration and cool hits in a piece you can take anywhere. Ideal for first-time bong users, travel sessions, or anyone who appreciates a small piece that punches above its weight.

All Human Grade beaker bongs are available in multiple color options and come securely bubble-wrapped and boxed with a unique barcode and color identifier sticker for authenticity.

Human Grade Dab Rigs

Human Grade's dab rig collection is built around recycler technology — designs that continuously cycle water and vapor through multiple chambers for cooler, smoother, more flavorful hits. Every rig is handcrafted from 100% borosilicate glass, features a 14mm female joint, and ships with a quartz bucket banger and matching carb cap included so you're ready to dab straight out of the box.

Stubby Klein Recycler — A compact 7.5" powerhouse featuring a Klein upcycler design and built-in oil catch. The Klein recycler continuously drains and spins water for ice-cold, flavorful hits with zero splashback. Despite its pocket-friendly size, this rig delivers performance that rivals pieces twice its size. Available in multiple color accents.

Dualing Recycler — An 8.5" rig with dual uptake arms, a built-in oil catch, and smooth recycling action. The dual uptakes provide enhanced airflow for richer flavor and smoother hits, while the recycler design keeps vapor circulating for optimal cooling. Bold color accents and a compact footprint make it both a performer and a looker.

Straight Recycler — Standing at 10.25" tall, this vertical recycler is built for serious concentrate enthusiasts who appreciate seamless airflow and smooth pulls. The precision-engineered recycler system continuously cycles water, cooling vapor efficiently while minimizing splashback. The tallest rig in the Human Grade lineup, it offers maximum filtration in a sleek, minimalist frame.

8.5" Swiss Incycler — An internal recycler (incycler) featuring Swiss-style percolation holes that break vapor into fine streams for maximum cooling and flavor extraction. The incycler design keeps all the action inside a single chamber for a cleaner look and easier cleaning.

NEO Dab Rig — A compact, uniquely styled rig that delivers smooth function in a distinctive silhouette. The NEO stands out in the lineup for its modern design language while maintaining Human Grade's commitment to thick glass and reliable performance.

Human Grade Bubblers

For smokers who want water filtration in a handheld format, Human Grade offers bubblers that bridge the gap between pipes and bongs.

Human Grade FAQ

What is Human Grade?

Human Grade is a smoking accessories brand focused on delivering premium-quality glass and accessories at accessible price points. Their product lineup includes beaker bongs, recycler dab rigs, bubblers, hand pipes, quartz bangers, ash catchers, aluminum grinders, and dugouts. All glass products are handcrafted from 100% borosilicate glass, and their grinders are precision-machined from premium aluminum.

What material are Human Grade products made from?

Human Grade glass products — including bongs, dab rigs, bubblers, hand pipes, ash catchers, and downstems — are all handcrafted from 100% borosilicate glass. Borosilicate is laboratory-grade glass known for its heat resistance, durability, clarity, and chemical inertness, meaning it won't leach flavors or contaminants into your smoke. Their grinders are made from premium aluminum with precision-machined teeth and magnetic closures.

Do Human Grade dab rigs come with a banger?

Yes. Every Human Grade dab rig ships with a 14mm quartz bucket banger and a matching carb cap included, so you're ready to dab right out of the box. You'll just need a dab torch, a dab tool, and your concentrates to complete the setup. Human Grade also offers upgraded bangers like the Terp Bubble Slurper and Full Weld Terp Slurper Set for enhanced performance.

What joint size do Human Grade pieces use?

Human Grade dab rigs use 14mm female joints. Human Grade beaker bongs also use 14mm female joints and come with removable 18mm to 14mm downstems, which gives you flexibility to use different downstem sizes or upgrade to aftermarket options. Their ash catchers are available in both 10mm and 14mm sizes with 45° or 90° joint angle options.

Are Human Grade products good for beginners?

Human Grade products are excellent for beginners. Their beaker bongs come ready to use with a bowl and downstem included, and their dab rigs come with a quartz banger and carb cap. The designs are straightforward and user-friendly, and the affordable pricing means you can get into quality glass without a major investment. The 6" Mini Beaker Bong and the Stubby Klein Recycler are particularly good starting points for flower and concentrate smokers respectively.

What is a recycler dab rig?

A recycler dab rig continuously cycles water and vapor through multiple chambers or pathways rather than letting it sit in a single static chamber. This constant recycling action cools the vapor more efficiently, preserves terpene flavor, and minimizes splashback. Human Grade offers several recycler styles including the Stubby Klein Recycler, Dualing Recycler (with dual uptakes), Straight Recycler (vertical design), and Swiss Incycler (internal recycler with Swiss-style percolation holes).

What is the difference between Human Grade's Klein, Dualing, and Straight recycler rigs?

The Stubby Klein Recycler (7.5") uses a Klein upcycler design where water drains through external tubes back to the base, creating a spinning effect for maximum cooling in a compact package. The Dualing Recycler (8.5") features two separate uptake arms for enhanced airflow and richer flavor. The Straight Recycler (10.25") uses a vertical recycler design for seamless, uninterrupted airflow in the tallest rig in the lineup. All three include built-in oil catches, 14mm joints, and come with quartz bangers and carb caps.

Can I use a Human Grade beaker bong for concentrates?

Human Grade beaker bongs are designed primarily for dry herb, but you can convert them for concentrate use by replacing the flower bowl with a compatible 14mm quartz banger. However, for the best concentrate experience, Human Grade's dedicated recycler dab rigs are purpose-built for concentrates with features like oil catches, recycler function, and smaller chambers that preserve terpene flavor better than a larger beaker bong would.

What is a Human Grade ash catcher and do I need one?

A Human Grade ash catcher is a glass attachment that sits between your bowl and your bong's joint. It intercepts ash and debris before they enter your bong's water chamber, keeping your main piece cleaner for longer and adding an extra layer of filtration for smoother hits. If you find yourself cleaning your bong frequently or want slightly smoother draws, an ash catcher is a worthwhile addition. Human Grade offers a Tube Ash Catcher and a Recycler Ash Catcher, both available in 45° and 90° angles to match your bong's joint configuration.

How do I clean Human Grade glass?

Human Grade products are designed with easy cleaning in mind thanks to smooth interior surfaces and detachable parts. For a thorough clean, disassemble all removable pieces (bowl, downstem, ash catcher), place each in a zip-lock bag with isopropyl alcohol and coarse salt, let soak, shake gently, and rinse with warm water. For dab rigs, Q-tip your banger after every session while it's still warm to prevent buildup. Change your water regularly and do a full deep clean weekly for the best flavor and performance. You can also use a dedicated bong cleaner for faster results.
