These Extra Large, 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.The 16 inch extraction tube is 44 mm (about 1 3/4 inches) in diameter with a 4 mm wall thickness. The 16″ holds about 140 grams of unpacked or 280 grams of packed flower. Stickers may vary. The tube kit is shipped with two stainless steel screens and a tool free clamp.
I also sell 10″ and 21″ tubes in the same diameter and 32 mm diameter tubes. 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. The conical nose gives these tubes extra strength. No “adapters” necessary. The big 21” tubes I sell are perfect for making large batches of concentrates and oils. The other end is flared slightly to hold your filters.
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.
