It is a nice example of a sep. I've never had another, but it is the better of the ones I've used in the past. But this one is mine for my home lab. ðŸ˜

It works but barely. For the price, I expected more. The passthrough hole in the stopcock does not line up properly with the passages from the vessel or the output tube in two of three axis. The depth that the stopcock sits into the taper in the glass, and the intersection of the vertical glass channel with the glass stopcock taper are both off.The workaround is to adjust the tension on the retaining nut so that it is very loose, which causes a leak around the stopcock. Even with this workaround, more viscous fluids do not flow well due to the misalignment of the vertical passageway.Hopefully it's just a one-off that slipped through QC. We'll see what the manufacturer says...

As described. When arrived it was not broken in box which was surprising. The stipe is actually thicker than most brands. Best sep funnel Ive ever used and I think Ill never go back. Glasco is a winner in my book.

Packaged very nicely. Extra packing around the box in a box. Spigot is a lower quality but works fine.

The first one I ordered arrived broken. I returned it and received a replacement. The stopcock valve on the second funnel has a leak. Unfortunately I waited 6 weeks to try it out and it's too late to return or exchange. Disappointed and unable to use

I have done 4 yeasts and this has been great. Saving me money by not having to purchase yeast. I can save my yeast and brew more beer. Larger than I really need till now, but worth every penny.

Stopper and valve are a precise fit. Conical Seperatory Funnel has generous volume and fairly large opening for pouring fluids into.
