Circle H Institute

Circle H Institute is dedicated to furthering the research, education and promotion of hydrosols. Members pay a fee to become a part of Circle H Institute, which helps support research and gives access to all the analysis, abstracts and education materials that founder Ann Harman has access to. As research continues to grow, the body of work will grow and you will be a part of it!

Donation: One year membership as a Hydrosol Supporter, which includes access to the members-only website, free submission of 1 hydrosol sample for GC-MS analysis or 5 free microbiology tests during membership year.
