I guess they figured that the patent had expired or that nobody would care.<\/em><\/li>\n<\/ol>\n\n\n\n<p><em>I really don\u2019t know if they actually made any machines or not.&nbsp;&nbsp;When I first saw the website a few years back, the machines were listed as \u201cout of stock\u201d when an order is placed, as is the case today.&nbsp;&nbsp;Maybe they just took pictures of an ISO2 and put

alt=\"\"\/><\/figure>\n\n\n\n<p><strong>Central components<\/strong>&nbsp;<\/p>\n\n\n\n<p>The ISO-1 through ISO-4 are all reflux boilers and work basically the same way.&nbsp; The heat from light bulbs in the lower chamber boils off the solvent in the pot above it, allowing the vapors to rise and contact the chilled head, where they re-condense and rainfall back through basket.&nbsp;&nbsp;<\/p>\n\n\n\n<p>If the basket contains plant material, the system acts as a soxhlet and the solvent dripping through the material, dissolves the essential oils and carries it with it.&nbsp; If the basket contains a 500 ml beaker, the refluxed alcohol dripping from the chilled head is captured, leaving the essential oils behind in the lower pot.<\/p>\n\n\n\n<p>That allows you to both extract the essential oils and recover the solvent in the same machine.&nbsp; It also allows you to recover ethanol after either a QWET extraction or after winterizing BHO.<\/p>\n\n\n\n<p>That means it can do whole plant extractions start to finish, or be used to recover the ethanol from a QWET extraction, or BHO winterizing.&nbsp; It can therefore be used for both full plant extracts, as well as vaporization concentrates.<\/p>\n\n\n\n<p>For our first test we recovered about a quart of winterized BHO, and began by filtering it.&nbsp; Since it was such a small amount, we didn&#8217;t bother with vacuum and just let gravity have its way with it, while Carla&nbsp; wiped down all the contact surfaces with Clear Springs 190 proof.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img

solution.<\/p>\n\n\n\n<p>The ISO-3 can clearly do ethanol recovery from either a QWET or BHO winterizing, but because of changes in local regulations, we were unable to test the soxhlet feature in our current lab.<\/p>\n\n\n\n<p>Since the alcohol recovery system clearly does work well, ostensibly the soxhlet extraction portion also does.&nbsp; More test to verify that later.<\/p>\n\n\n\n<p>Ostensibly the best feature about D Gold&#8217;s Isomizers, is that because of the low heat, they can be turned on and mostly ignored as you conduct other business.&nbsp; They are highly forgiving, with danger of wrecking a batch low, and the size is about perfect for ma and pa, with maybe a small circle of friends.&nbsp;<\/p>\n\n\n\n<p>SN0001 was of course a beta test unit, so even as we ran our tests, D Gold was continuing to refine his design, one of which was to upgrade the inner basket and the other was to move the light bulb into its closest proximity setting, and add a dimmer switch to control heat.<\/p>\n\n\n\n<p>Carla and I both applaud the basket upgrade, but Carla is ambivalent about moving the light bulb closer, because it reduces the forgiveness of the process.&nbsp; One of the features she most admired about the original design and setting, is that you could be forgetful with minimal exposure, and with the new design full on, some of that margin has been taken away.<\/p>\n\n\n\n<p>Of course you can still adjust the light bulb further away so that full on, it still doesn&#8217;t burn the concentrate, if you prefer forgiveness.<\/p>\n\n\n\n<p>Hee, hee, hee, for those of yall who covet a larger unit, D Gold recently added the ISO-4 Kilomaster, which we will be testing next.&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>For perspective, let&#8217;s start with a trip down memory lane for ya&#8217;ll brothers and sisters who became aware of the cannabis
