Separates the oil and hydrosol by gravity. Hand drilled. This has been tested and it works great. You would collect and you could walk away and not worry if the flow changes. More info and videos coming soon. This is handmade. This is not mass produced cheaply. With any purchase we are available to help over a phone or email. The customer at the bottom photo, got our oil still and separator and that weekend he got it, made 177 ounces of Lavender oil and Rosemary Oil, you can see below. So it is not hard to distill at all.
