Botanical Extraction is the process of isolating and retrieving specific or active compounds from plants for later use. Since plant materials are complex mixtures of different chemicals, the primary challenge of botanical extraction is separating the various compounds found in different parts of the plant and recovering the desired product.
Filtration is one method that can be used to meet that challenge by further separating or purifying desired compounds. The filtration products in this category are the basic components to create a small-batch vacuum filtration system that can be used to remove particulates and other contaminants to ensure the purity of the final products.
A complete, basic vacuum filtration system for herbal/botanical extracts consists of a vacuum filter holder, membrane filters, a trap bottle or flask, and a vacuum pump. Manifolds and other optional accessories can be used to modify the filtration process to best suit the project requirements and throughput volume.
In addition to the products found here, Sterlitech also offers numerous custom-made filters and filter systems for more demanding applications. Please contact us directly for more information.
