First announced this past spring, the Botanical Extraction section of our website is now up and running! This section houses everything you need to make a complete, basic vacuum filtration system for herbal/botanical extracts including vacuum filter holders, membrane filters, trap bottles or flasks, and vacuum pumps. You can also find optional accessories, such as manifolds, that can be used to modify the filtration process to best suit the project requirements and throughput volume. If you have a need to perform any of the following applications:
- Cold-filtration to remove lipids or waxes, often called winterizing
- Clarification or plant debris removal
- Bacterial removal (using 0.2 or 0.45 micron PES filters)
- Batch processing with manifolds
- Ethanol washing
Then head to our Specialty Applications Section to find the best equipment to work with your botanical extraction process.
