hi,
jumped in a bit quick with the MEK extraction question, especially with it being my first post on this site, but I just thought I'd mention for what it's worth that this type of extraction, like with alcohol extractions, extracts the chlorophyl (plus tars and waxes) to and makes for a dirty tasting oil like the ones you used to get back along.. dark brown with THAT taste.
I'm currently sticking with the butane extractions as this gives the best and purest results and I use the coffee pot method I learned about through this site a little while back as it is the quickest and easiest method that I've tried.
One question, if you don't mind, what are the best filters that people have found for using as all the coffee filters I've tried have little perforations (or aroma pockets!) which let too much through. Where can you get lab grade filters, anyone know?
Cheers,
Gro.

Hello ,
Farnell or RS Components should stock lab grade filter paper . I've not had too much luck with coffee filters , even after making a 'washer' from another piece of filter paper to form a tighter seal , I'm still getting the odd particle coming through here and there . Did not have this trouble with the papers that came with my Honeybee

If I find the lab papers , I'll let you know where I found them and the order number

cheers
