Our pumps have undergone and passed the third party peer review process through Pressure Safety Inspectors (PSI) as part of the Anion Rev. 5 review. They have been certified as safe for use in a C1D1 extraction lab environment for use with butane, propane, or any mixture thereof.
*Please note that many jurisdictions may still require certification of the pump integrated with the extraction systems as a complete unit.
