Closed loop butane extractors are becoming more and more popular as more people learn about the benefits of essential oils. Butane is the most effective solvent for extraction because it is non-polar. Our closed loop machines are able to work with a variety of different solvent solutions including: N-Butane, Iso-Butane and N-Propane, or any combination of the three. Terpp Extractors wants you to be happy with your extractor, so we will walk you through the process from start to finish. Once your order is placed, your closed loop extractor will be built, tested and shipped within about 1 week. After that, we will provide you with comprehensive training and helpful reference materials so that you will have all the information you need to get started with your first batch of materials. As you become more familiar and efficient with your butane extractors, we will be happy to help you pick out accessories that will add to the efficiency of your process and improve the quality, as well as giving you more information about the latest techniques and practices for high yield closed loop extraction.
