This package includes one Extra Large 20 inch extraction tube, a tool free clamp and two filters.
These Extra Large, Thick, Heavy Duty Concentrate Extraction Tubes, are made of German Duran Schott glass. The 20 inch extraction tube is 44 mm (about 1 3/4 inches) in diameter with a 4 mm wall thickness. The tube kit is shipped with two stainless steel 50 micron screens and a tool free clamp.
We also sell 12 and 16 inch tubes in the same diameter and 10, 12, 16 and 20 inch tubes in the 32 mm (about 1 1/4 inch) diameter. Check our listings!
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.
Multi Packs are available on a separate listing. https://www.theglassunderground.com/
