I know II'm late to the thread but I'm new to the site.
We purchased an Apeks SCFE more than a year and a half ago. Our experience with Apeks has been fantastic. When we first ordered our machine we made some rookie assumptions about the entire process and anxiously awaited delivery. Once we received the machine, it looked great and we dug right in and produced our first extract. Then, the question was what do we do with it. So, we began experimenting. There are no videos that show you all the steps, there isn't an instruction manual that will walk you through the many different settings that are available and there are plenty of "consultants" who want to charge $10-$20k to "show you how to become an extract artist". The bottom line is this; what we are all doing is science not art. Our objective is to produce something great and then to be able to reproduce it over and over again. Artists are great at creating a one of a kind piece but it is the "scientist" who can replicate the process. Andy Joseph, Apeks CEO, was the first person to point that out to me and he's been in touch with us a number of times since we purchased his equipment. In fact, early on when we had a problem while experimenting with our system, Andy called us to walk us through the problem and solved it over the phone in 20 minutes. Over the two years we've worked with Apeks, I've found them to be top of my list when it comes to customer service...and for an old guy (I'm 65)...I've worked with every kind of vendor you could think of. From their sales engineer Craig H to their director of sales Shawn L to their newest (not so new anymore I guess) service engineer Nick Y to their real head of the company, Kristen J, Liz L and Tina H and all the team, they bend over backwards to make sure we are getting optimum performance from their equipment.
Now to performance. As with anything, you must start with good material...PERIOD!! We test everything, we know what's going in and we know what's coming out. A piece of equipment like this has a number of variables to work with...those that are easily recalled such as pressure settings (sub critical vs. super critical); temperature settings; extraction time; component pieces to use; and more. these settings are crucial in creating specific types of extract. Apeks machine does what it promises to do and if you experiment scientifically, you will be able to do a great CO2 extraction and you will be able to reproduce it time and time again.
For us, the bottom line is a) the machine is the best that I've found and we spent 10 months due diligence before ordering one and b) the customer service from Ohio and Colorado offices has been the best I've encountered.
Yes, I'm a believer and would be happy to discuss with anyone. We are in Southern California and we don't get discounts, don't take bribes and we still tell anyone who asks that Apeks is the best...wait, as a former Pittsburgh boy, Shawn did send me some Mancini's bread packed in the crate with our shiny new machine when we first got it. While I don't look back from my move to the west coast, some things I still miss and that was one of them. I guess I do have a complaint...they haven't sent anymore Mancini's bread.
