Sep.Funnel or what ?


Because I'm emigrating from UK I thought I'd 'stock up' on used Quickfit via eBay when suitable (cheap),
I just won this item that is described as 'Vintage Pyrex Separating Funnel Double Tap Laboratory Glassware'
but looks more like a gas sampling tube with 3-way valves.
Anyone know of a specific use for this configuration ?

some kind of oil/water separator?

Second one looks like a dean stark trap, but i think the first one has a gas liquid separation (or maybe addition) function, but I'm no expert!

i thought dean starks had a tap on one arm(left arm as shown above) letting you drain the lower phase.

I agree that the second photo is of a separator.
Some have taps and some, like this one, have graduated receivers,
e.g. determine water (or heavier fraction ) content of liquids.

I think that I could configure the first piece as a partial takeoff head. e.g.

oops! ... "downjere" = "down here" ... finger trouble and not checking properly :(

Found this in the glass shop at UC Berkeley. I believe it lived on the dean's desk for a while before it was broken. It has uranium glass connections and a strange green orb at the bottom.

Some kind of old fashioned sensor maybe? Density, viscosity.....?

It looks like some gas drying maybe generation and a I'll call it a gravity separator....a sort of decanter? The first one looks like some sort of separator also?

The first is some kind of specialist volumetric flask. Note the little lines between each of the three bulbs. I guess the idea is to measure three immiscible liquids in one hit for a batch process. Actually, they would not need to be immiscible on second thoiughts.

To me they look like the flasks are just balanced on top of each other.




i am wg48 but not on my usual pc hence the temp handle.

I swear, it's one flask :)

That's a good guess, but I'm wondering if it wasn't made using volumetric flasks simply b/c that is what was on hand. Who knows if this was even meant to be functional and not some goofy science glass blowing project that used old flasks that had gone out of calibration over time (can happen from heating vol flasks too hot or even drying them too hot).

it wouldn't be very precise as the volume of the sum of two miscible liquids is rarely the sum of each volume, so they should be measured separately (not an ideal solution)

Which is why I originally thought immiscible. But even if the liquids were miscible, you would not get that much mixing with that design. And it might be for an application where density changes are negligible -- such as combining three dilute aqueous solutions in a known ratio.
If my idea is correct then it is for a repeated batch process. Repeatability and uniformity of outcome might well be more important than measurement precision.

The bottom flask looks like a volumetric flask. The volumes of each part all look similar, so maybe it was for a process that was done at 1/3, 2/3 or 100% scale, and they could use one flask for any of them without having to do up to three measurements. That seems pointless, but I have seen dumber things.

The second and third look like drying tubes of various designs. I have seen these types before over the years, but not widely used now.

I can't believe the 3 volume flask was ever part of a practical process - can you imagine the difficulty in emptying it (plug flow) not to mention cleaning it, and all without any benefits in terms of accuracy or handling. My guess is that it's either a piece of artwork/glass blowing practice or that it was made to be the yard of ale from hell!

There was a version with 2 bulbs and lines called a Giles flask.

I have used something similar to the first one for a Kugelrohr, but in that case it was just two bulbs, one to distill from and one to collect, maybe this could be some sort of fractionation with that sort of setup.

Wow, I did not expect them to be so hard to identify. They originate from a high school maybe 40 years ago. I'll see if I can find someone there who knows what are they

Have you determined the liquid volume to whatever lines are present?

Top one is 40ml and then 100ml and 100ml.

The equipment comes from around 1960 from one technical highschool. I've asked them if they could answer what it is, but since it's holiday here, I think it'll take a while :)

two and three are drying towers, useful when the dessicant becomes dissolved in water , as it drips down and is removed from the stream of gas being dried. i think Vogel 3rd has an illustration of one when explaining how to produce dry ammonia gas from the solution.

The custom volumetric was likely designed to make a certain solution, like 1/6th X in 50:50 ethanolic water. Many tinctures were made that way. Even vanilla flavor is often made from concentrated ethanolic vanilla which is diluted with water and more alcohol to make a "standard" solution.
