Harvest & curing
by EHLE
The EHLE-X-trakt glass extractor is an all-glass BHO extraction tube designed for producing the cleanest possible concentrate without metallic or chemical off-flavours. Certified by Dexso — the Austrian brand known for setting the bar in extraction equipment — this 20cm borosilicate tube replaces the steel mesh screens found in standard extractors with a sintered glass frit. The result: nothing between your plant material and your collection dish except glass.
Most butane extraction tubes use stainless steel mesh or coffee-filter-style screens at the bottom. They work, but metal screens can impart a faint metallic taste to your oil, and paper filters risk leaving fibres behind. The EHLE-X-trakt sidesteps both problems by using a sintered glass frit — essentially thousands of tiny glass beads fused together into a porous disc. Butane passes through, plant oils pass through, but particulate stays behind. No coating, no steel, no paper.
Pick one up and you'll notice the weight immediately — it's heavier than the acrylic tubes you might have used before, and the walls are noticeably thick. The borosilicate glass is the same stuff used in lab equipment: resistant to thermal shock and easy to clean with isopropyl alcohol. The screw thread at the bottom seals flush against the glass frit, so there's no gap for material to bypass the filter. Two ground-glass joints keep everything airtight during the run, and a small gas inlet hole at the top accepts a standard butane canister nozzle.
One honest limitation: glass is glass. Drop this on a tile floor and it's done. The roll-away protection — a small ridge moulded into the tube — stops it rolling off your workbench, which is a smart touch. But you still need to treat it with more care than a steel or silicone extractor. If you're clumsy in the workshop, keep that in mind.
The EHLE-X-trakt ships as a complete, ready-to-use unit. Here's what's in the box:

The glass frit is the single biggest reason to choose the EHLE-X-trakt over a conventional tube. Here's how it stacks up against a typical stainless steel extractor in the same size range.
| Feature | EHLE-X-trakt (Glass) | Standard Steel-Screen Extractor |
|---|---|---|
| Body material | Borosilicate glass | Stainless steel or acrylic |
| Screen material | Sintered glass frit | Stainless steel mesh (typically 25–50 micron) |
| Taste purity | No metallic or coating residue | Possible faint metallic taste |
| Durability | Fragile — handle with care | Very durable, drop-resistant |
| Cleaning | Isopropyl soak, rinses clear | Isopropyl soak, may stain over time |
| Certification | Dexso certified | Varies — most uncertified |
| Visual inspection | Transparent — see the run in real time | Opaque — guesswork |
The transparency is an underrated advantage. With a glass tube, you can watch the butane wash through your material and see when the solvent runs clear — that's your cue to stop. With an opaque steel tube, you're estimating. We'd pick the EHLE-X-trakt every time for flavour-critical runs, but if you work outdoors on rough surfaces, a steel tube is more forgiving.
BHO extraction involves flammable gas under pressure. Always work outdoors, away from ignition sources. No smoking, no open flames, no indoor use. Read the included manual before your first run.
EHLE is a German glass brand with a solid reputation in the smoking accessories world — they've been blowing borosilicate for years, and you can feel it in the wall thickness of this tube. The glass frit is the star, though. Sintered glass screens are standard in chemistry labs but rare in consumer extraction gear because they're expensive to produce. Most manufacturers take the cheaper route with steel mesh. EHLE didn't.
The Dexso certification is worth noting. Dexso is an Austrian company that makes their own line of extraction equipment and butane gas. When they put their name on a third-party product, they're vouching for the build quality and the seal integrity. It's not a marketing badge — it means the tube has been tested to Dexso's standards for gas-tightness and filtration.
The ground-glass joints deserve a mention too. These are the same type of joints used in laboratory glassware — precision-ground surfaces that create a gas-tight seal without O-rings or rubber gaskets. Fewer consumable parts means fewer things to replace or lose. That said, if you do chip a joint edge, the seal is compromised and the tube needs replacing. Handle the joints carefully when assembling and disassembling.
We've been stocking extraction gear since the early days, and the number one complaint with cheap extractors is always the same: off-taste. People spend weeks growing and curing their material, then run it through a tube with a corroding steel screen and wonder why the oil tastes metallic. The EHLE-X-trakt solves that problem completely. Glass in, glass out, nothing else.
The 50mm diameter is generous for a "small" extractor. You can comfortably fit 8–12 grams of dried material per run, depending on how finely you break it up. For personal use, that's a solid amount. If you're running larger batches regularly, you'll want to look at bigger tubes — but for most people, this size hits the sweet spot between capacity and handling comfort.
Complete your extraction setup with a can of Dexso butane gas — it's the same brand that certified this extractor, and their gas is triple-refined for cleaner runs. A Pyrex collection dish and a silicone concentrate container round out the kit nicely.
The glass frit is built into the screw-thread base assembly. If it cracks or chips, you'd need to replace the entire base section. In practice, the frit is well-protected by the tube walls — breakage usually only happens from drops or overtightening.
Soak the entire tube in isopropyl alcohol (90%+) for 15–20 minutes. The porous glass frit traps residue, so a longer soak helps. Rinse with warm water and let it dry completely before the next run. Avoid poking the frit with sharp objects.
The gas inlet hole accepts standard butane canister nozzles — the same type used for refilling lighters. Most 300ml extraction-grade canisters fit without an adapter. One can is typically enough for a single run in this size tube.
No. The ground-glass joints and sintered frit can be damaged by the mechanical action and detergents in a dishwasher. Hand-wash only with isopropyl alcohol or warm soapy water.
With a 20cm length and 50mm diameter, expect to fit roughly 8–12 grams of dried, broken-up plant material per run. Don't grind it to powder — you need airflow through the tube for the butane to wash evenly.
Glass is chemically inert — it won't react with butane or plant oils, so you get a purer-tasting concentrate. It's also transparent, letting you see when the wash runs clear. The trade-off is fragility: glass breaks if dropped, steel doesn't.
Dexso is an Austrian extraction equipment brand. Their certification means the EHLE-X-trakt has been tested for gas-tightness, filtration quality, and build integrity to Dexso's production standards. It's a quality assurance mark, not just branding.
