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 16 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/
