I do love Stony Lab glass, fine grit is excellent. Forgot my filter papers and will never forgive myself for trying to use it anyway.... 😔

I love this! It's Stonylab so you know its going to be good. I wondered if it would have issues with suction as there was no rubber collet to make the seal, but a touch of any liquid (preferably one that will not alter or react with your works, in case it drips), and it created a great seal. No issues at all, and works with any 24/40 device.

Great vacuum filter. Glass is very well made. The ground glass joint fits snug with other pieces. Corresponding filter papers fit (mine is 94mm). If you are looking for one of these, this is a good one.

This funnel has proven to be an essential tool in my lab, allowing me to filter chemicals that cannot be effectively filtered by traditional filter paper or diaphragms.It can be easily used with various lab equipment, such as filter Erlenmeyer flasks and filter adapter cones. This makes it incredibly convenient for multiple applications, including chemical analysis, petroleum industry tasks, and pharmaceutical industry processes.The G3 15~40 μm Nominal Max. Pore size ensures efficient filtration, providing reliable results every time. Additionally, this funnel is compatible with StonyLab Qualitative/Quantitative Filter Paper Circles in a 94 mm diameter, making it even more convenient for lab work.However, it is essential to note that this funnel is unsuitable for filtering hydrofluoric acid, hot concentrated phosphoric acid, concentrated alkaline solutions, and similar substances. Following the manufacturer's instructions and guidelines is crucial to ensure safe and effective use.Maintenance of this funnel is relatively easy. It is recommended to clean the funnel immediately after use and keep it clean and dry when stored. The high-quality borosilicate glass construction ensures durability and longevity, making it a reliable investment for any laboratory.

When I got this funnel from the seller, I was displeased to see that it was cracked and scratch.However, after contacting the seller, they fixed my problem by sending me a brand new one. The new one is flawless!! It's thick and sturdy, and it filters precipitate/particles out of solvent well!The Seller was prompt and willing to listen to all of my concerns.10/10 would buy from them again.

Good solid product has been through many bumps and bangs and is still in one piece do yourself a favor though and go ahead and get yourself an Erlenmeyer with identical ground glass joints and a lab vac

These frit filters are sweet, and as a glassblower(non scientific) these things truly blow my mind. It’s a filter made of finely crushed glass particles formed into a disc. Besides for being an outstanding example of engineering, the fine filters are outstanding, and saves a few bucks on buying filter paper ya really don’t need it as long as ya wash it well, but make sure ya got a pump to pull a vacuum, water will barely go through the fine filter without negative pressure, and my suggestion don’t waste your money on the trigger style pumps all I’ve ever gotten were junk.
