This package includes TWO Extra Large 20 inch extraction tubes.
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 20 inch extraction tube is 44 mm (about 1 3/4 inches) in diameter with a 4 mm wall thickness. The 20 inch holds about 180 grams of unpacked or 320 grams of packed flower. Stickers may not included.
We 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 20 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. https://www.theglassunderground.com/
