Manual BHO Extraction Tube 80g – 304/316 Stainless Steel Closed Column System

The Manual BHO Extraction Tube 80g is a professional-grade, stainless steel closed-column system designed to transform your dry herb into pure, golden concentrates with maximum yield and zero hassle.

Before upgrading your setup, making butane hash oil usually means wrestling with basic open blast glass or plastic tubes that freeze your hands and waste your precious gas.

You end up losing yield because the butane rushes through too fast without properly soaking the material. Plus, holding a freezing cold tube is not just uncomfortable—it's sketchy, and trying to keep the temperatures low enough to avoid pulling unwanted chlorophyll feels like a constant, frustrating battle.

This manual extraction tube completely flips the script by giving you a controlled, hands-free environment. Thanks to its inlet and outlet valves, the gas fully soaks your buds, while the included tripod and dry ice sheath keep everything stable and freezing cold, ensuring a flawless, high-yield run every single time.

Before running your BHO extraction

Getting ready for a blast requires a bit of prep to ensure safety and top-tier quality. You need to pack your tube correctly and set up your workspace in a highly ventilated area—ideally outdoors. Since this tube holds around 80 grams of dry plant material, you'll want to make sure your buds are properly dried and stored in odor-proof bags before grinding to maximize the surface area for the butane to do its magic.

• Pack it tight, but not too tight: Ensure the plant material is evenly distributed to avoid air pockets.
• Chill your material: Freeze your buds and your butane beforehand to keep unwanted waxes out of your final product.
• Set up the tripod: Secure the tube on its stand so you don't have to hold it during the freezing extraction process.
• Prepare the dry ice sheath: Load the sleeve with dry ice to maintain ultra-low temperatures throughout the run.

During the extraction process

Once you open the valves and introduce the gas, you'll immediately notice the difference from a classic open blast system. Because this is a closed system with valves, the butane doesn't just shoot through; it bathes and soaks the cannabis completely. This soaking phase is crucial because it dissolves a much higher percentage of trichomes, giving you a significantly richer and more concentrated yield.

While the magic happens, the dry ice sheath works overtime to keep the internal temperature plummeting. This prevents the solvent from pulling chlorophyll and plant lipids, keeping your extract golden and shatter-clear. And because the tube is resting safely on its tripod, your hands stay warm and safely away from the freezing steel.

If you are looking to upgrade your entire setup, checking out our BHO extraction gear will give you all the extra tools you need to perfect this phase.

After the blast: results and maintenance

When the run is over, you are left with a massive puddle of premium resin ready to be collected with your favorite dabbers and purged. Thanks to the included vacuum pump, you can easily purge the remaining resin stuck inside the tube, ensuring absolutely nothing goes to waste. The yield is noticeably larger and cleaner than what you'd get from standard tubes.

Cleaning this 316 and 304 food-grade stainless steel beast is a breeze. Just flush it with a bit of alcohol, wipe down the valves, and let it dry. It's built like a tank, so with minimal maintenance, it will last you a lifetime of extractions.

Short and long-term advantages of this BHO tube

• Because it features inlet and outlet valves, you can soak the material completely, which means you get a much higher yield and don't waste any butane.
• Because it includes a dry ice sheath, it maintains sub-zero temperatures during the run, which means your final concentrate will be pure, golden, and free of dark chlorophyll.
• Because it comes with a sturdy tripod, the tube stands on its own, which means you keep your hands safe from frostbite and can work comfortably.
• Because it is made of 316 and 304 stainless steel, it withstands extreme pressure and temperatures, which means you have a safe, professional-grade tool that will last forever.
• Because it includes a vacuum pump, you can extract every last drop of resin from the tube, which means you maximize your profits and never waste a single gram of your harvest.
• Because it holds up to 80 grams of material, you can process large batches at once, which means you save hours of work compared to running multiple small tubes.

Frequently Asked Questions

Is this tube safe for beginners?

While the tripod and valves make it much safer and easier to use than open blast tubes, BHO extraction involves highly flammable gases. It should only be operated by users with specialized training or a deep understanding of safety protocols, always outdoors.

Do I need to buy filters separately?

No, this manual extraction tube includes its own filters, so you are ready to start packing and blasting right out of the box.

Can I use regular ice in the cooling sheath?

You can, but dry ice is highly recommended. Dry ice reaches much lower temperatures, which is the secret to keeping plant waxes and chlorophyll out of your final BHO extract.

How do I clean the stainless steel tube?

Simply disassemble the parts, remove the spent plant material, and clean the stainless steel components with isopropyl alcohol. Ensure all valves are clear of sticky residue before your next run.

Personal Experience of Pevgrow’s CEO (Alan)

When I first got my hands on this 80g closed-column tube, it completely changed my extraction Sundays. Before this, I was freezing my fingers off with basic glass tubes, rushing the process, and getting mediocre yields. Now, I prep my material by freezing it overnight. I set up the tripod in my backyard, pack the 80 grams tightly but with enough breathing room, and load the sheath with dry ice.

During the run, the difference is night and day. Being able to close the bottom valve and let the butane actually soak the buds for a few minutes before releasing it makes the yield explode. I usually let it soak for about 3 to 5 minutes depending on the strain. After purging the remaining resin with the included pump, the clarity of the shatter I get is dispensary-level. Maintenance is just a quick iso-wash, and it's ready for the next round. If you're serious about your concentrates, this is the upgrade you need.
