## Customer Reviews

### ⭐⭐⭐⭐⭐ Get the right size.
*by J***E on June 2, 2025*

Works great for distilling hydrosol and essential oils in small quantities. I ordered the wrong size, I needed the next size up but it works!!

### ⭐⭐⭐⭐⭐ I wasn't sure what to expect for the price and am enthusiastically impressed!
*by C***E on November 30, 2022*

If you are looking for a quality separatory funnel for the price of a mediocre one, Stony Lab wins hands down! The stopper is precision and when turned upside down for a breather, it stays on without holding it. There are clips for this purpose and wouldn't advise it with anything but blue water.Stony Lab has an extensive line of laboratory grade glass and borosilicate extraction, distillation, test tubes, funnels, sieves/filters and flasks. This is a line that I would spend a little money on for an investment. I just ordered the lab stand to go with the separatory funnel.The distributor, J & D Tech, was very professional and was genuinely concerned about my satisfaction with the funnel. I let them know that they will be seeing several more orders for more gear, now that I found a reasonable price for a stellar product! Can't wait to get the stands!Thank you J&D Tech!My reviews aren't always nice and fuzzy but at least they are honest! If you care about the product, then you care about the quality!Chad Okeefe

### ⭐⭐⭐⭐⭐ Well built

I'll still probably break it
