There are TWO 12 inch extraction tubes in this multi pack. These Thick, Heavy Duty Concentrate Extraction Tubes, are made of German Duran Schott glass. They are shipped in a tube that will protect your glass when you are not using it. This 12 inch extraction tube is 32 mm (about 1 1/4 inches) in diameter with a 4 mm wall thickness. The 12 inch holds about 24 grams of unpacked or 32 grams of packed flower.
We also sell 10 and 16 inch tubes in the same diameter and 12 and 16 tubes in the 44 mm (about 1 3/4 inch) diameter. Our sandblasted Hott Glass tubes are the newest in our line. Check our listings!
I know what you need! The small hole is exactly the right size for extraction. No “adapters” necessary. The conical nose gives these tubes extra strength. The other end is flared slightly to hold your filters. All tubes are properly annealed and made of the highest quality laboratory borosilicate glass. Our big 21 inch tubes are perfect for making large batches of concentrates and oils.
This device is intended for extracting oils and concentrates from herbs, spices, and flowers. Glass is the best material to use for oil extraction. The purchasers of my products assume all responsibility, liability and risk.
Screens and clamps for multi packs are available on separate listings.
