About this item

  • Separate Liquids with Precision: Purer extractions lead to more accurate work. Precisely separate compounds using the glass separator funnel and the leak-proof PTFE stopcock. The separation flask is designed for solvent/liquid-liquid extraction and is an essential tool in any lab. We recommend you run an extraction at least 2-3 times for the best results (distillation may be needed to remove impurities).
  • Constructed To Lab and Industrial Standards: The American Fristaden Lab Separatory Funnel can handle tough, corrosive materials and high and low temperatures without breaking. The separating funnel is made with lab-quality borosilicate beaker 3.3 glass, which can handle much more stress than standard glass. The seperatory flask also features a corrosion-resistant PTFE stop cock.
  • Packed So It Won’t Break: Our glass conical separatory funnel, encased in sturdy foam packaging, will safely make the journey to your door.
  • American Company: Fristaden Lab is an American lab equipment company. We back the separatory funnel with a 1 Year Warranty. If you have any problems with or questions about the lab scale, please feel free to reach out and we would be happy to provide assistance.

I bought this for extractions. It's great, came in good packaging. I just wish they made an even bigger one

I have not used the product yet but it looks like it is going to do what I want. The shipping and the packaging were great.

Well, it works fine, though I noticed when operating the valve there was some weeping of liquid through the valve and toward the handle side. This wasn't an issue for me as I was using a very weak acid, but for stronger acids or bases this is highly unacceptable, however, this product should be avoided for such and it should state it within the description to be fair. Still it shouldn't leak at all, this a flaw. The valve and cover cap is plastic and not glass FYI.

Used it to separate water & honey. Didn’t work cause honey is water soluble but it did remove the other materials in the honey

Arrived on time but tip was broken. It is usable. Seller must ensure the product is in good condition before shipping it.

Great collector for my purposes. Picture shows a Rosemary extract that is in the finishing stages of setting.The stop cock mechanism works good as I tested it with water before using my extract.In the background there is a less quality collector that came with my distillation kit and the stop cock leaked. I sealed it with wax in an old school method but it’s not of quality that I would buy on its own.This is a great collector and the functioning stop cock is worth the little extra in price. It can take several weeks for an extract to completely settle and that stop cock is the key component to harvest your patient collection efficiently.I will be buying more collectors.
