The usalab kegs come with two 1.5ā ports with sight glasses on top, a six inch top port with dual dip tubes and a 2ā connection ā¦ and a 1.5ā drain portā¦ pretty tricked out

should i use Ping pong balls with the dome?
I used to make coffee in my buchner lol
Itās just a fancy chemex
@Siosis Unless youāre doing the work yourself, that price seems comparable or better than having a fabricator modify a single keg for you (in the US). If they do a lot of them, they (should) have tricks that make it easier, but that seems like fair amount of keg mod for $419.
I like the dual 1/2" dip-tubes and angled ports. I might have to steal the dual dip-tubes 
I recall poly-carbonate requiring special coatings to be resistant to ethanol, and question the longevity of the OEM sight glasses.

Dual keg receivers on a 50l. 
Going to plumb the vac feed in just like on the glass onesā¦and chances are Iāll only run one keg here. The other one goes on the feed line.

How can I get the one of those stainless fittings for my re-501? Dm with quote?
@GroovyOctopusLabs, just start digging through your spare tri-clamp parts. If I remember right, this is just a 2" concentric reducer with a 1.5" barbed cap with the appropriate sized silicone tube to connect to the kegs. No need for specialty parts. We didnāt order any special new parts. It was just what was on hand

Where did you get the clamp to hold it into place? The clamp looks speacial made.
Itās the stock clamp that came with the unit. I was really surprised myself! It helps to have a gasket that is flat on one side. Using the flat side against the glass helps when trying to pull vac.

Has anyone tried doing this adaptation to the actual condenser? Thinking about using a 6x36 shotgun condenser on top of the main condenser on a 20L rotovap. Shopping for the rotovap now so I donāt know the dimensions of the glass port on the primary condenser. Trying to keep as much solvent out of our cold trap as possible.

I actually have everything on the way to do this but on a reactor not a roto. Seems a lot cheaper and more modular than glass roto condensors

Iāll race you! Just ordered some stuff to throw a 3x18 on our 30L. Iāll throw some pics/specs up on what it does for our recovery rate.

Lol i got a head start already but hell yea Lmk what it does for recovery rate. Iām pairing it with a polyscience chiller. Iām adding a 3 way valve and another bellow hose between the bottom of the condenser and the keg but they havenāt come in yet.

Thatās a pretty slick setup. It would probably be pretty sweet for catching terps during decarb depending on how low the chiller goes, especially if youāre pulling vac on the top of the condenser. Iām probably being dense but what purpose is the 3 way valve going to serve?
I donāt have a fancy cryo chiller but I do have a near endless (215 Rton) supply of 6C water from our building chiller. Iām running a grundfos UP43 which should push some pretty serious flow so Iām excited to see what she can do.

Thanks i got that reactor cheap af so i tried to come up with a way to use it for ethanol recovery because i hit a bottleneck on my 5L roto. Yea Iām pulling vac from the top of the condenser and just pumping hot water through the jacket until i get silicone heat transfer fluid. The 3 way valve will have the bellow coming from the reactor to it then the condenser on top and a bellow connected to the bottom which connects to the keg so it has a flexible connection and i can shut the valve and remove the keg. This same setup could be added to a rotovap but with a 2ā tri clamp connecting where the condenser usually connects then connect that to a 2ā 3 way valve.
I like your chiller idea that seems way more cost effective than buying a 10k chiller, youād just need a good pump and more surface area on the condenser. What size shotgun condenser did you order?
Iām going to hook up a 3x18" that I have on hand and make sure the concept works and then probably order a 6x24.
We already use the chilled water for the glass condensers and itās awesome. we have a 5kw bath with 6 immersion circulators in it and heat is still our limitation (running at 46C usually). Iām afraid to hook that big a pump up to a glass coil though.
The best part is that that monster literally cost less than $10k off Craigslist ($9500 baby!). It was kind of a bitch to get running because it was decommissioned like 10 years ago and weāre in for probably $50k with the cooling tower (also Craigslist) and associated pumps/piping but it handles 15k sqft of grow with ease and loads like this are a rounding error on its capacity.
Next up is running a drop from the 4.5M btu boiler to fix that heating restriction.
