## Customer Reviews

### ⭐⭐⭐⭐⭐ Works well
*by J***K on March 20, 2025*

Packaged very well to prevent damage, working well, good for at home lab

### ⭐⭐⭐⭐ Have some reservations
*by G***A on August 13, 2024*

I got my PhD in organic chemistry and teach chemistry at the college level, so I have used many seperatory funnels in my time. I decided to get a set for some at home projects and was attracted to the low cost on these (ones I've purchased for lab have been over $100 a piece). Funnels arrived in good shape, no signs of cracks or breaks, in tight fitting thick Styrofoam. Filled them with water to test sealing and even with a few inversions no leaks, once I dialed in the correct tightness on the stopcock (see comment below)My reservations come from two things. First the stoppers are clearly not up to the same standard as ones I've used in lab. They are uneven and the bottoms show signs of breaks where the ground glass is not present. This doesn't impact the utility in the slightest, but most of the ones I have used are even with a slight chamfer around the base. Sloppiness like this always makes me worry where else they've cut corners. Second the gasket ring for tightening isn't as sturdy as normal. In order to tighten this to the degree needed to keep leaks from occurring at the stopcock, I needed to have it bulging out from the sides. Normally this wouldn't happen because it would be a stiffer material. I've known these to wear out but not until long use in the lab, with these I feel less certain.In the end, for the price, this is probably worth it you're not handling anything to dangerous and just need something cheap to get by with or to test out. For more involved use you might want to invest a bit more

### ⭐⭐⭐⭐⭐ nice budget sep. funnels
*by H***E on September 27, 2024*

These are pretty good separatory funnels. The glass is reasonably thick and they came without any cracks or anything like that. Having such small funnels is very useful when doing chemistry projects and you get down to using small amounts of whatever chemical you are working with. The small funnel makes it easy to not lose anything to the sides of the funnel like with a larger funnel. The stoppers are glass on glass which is nice and they fit snugly and the stopcock didn't have any leaks in my testing. For the price, I am happy with these separatory funnels, 5 stars!
