It fits a 24/40 flask and you'll need a rubber stopper, dear customer. br>Thank you for taking the time to read this, J. D Tech
It was a 60mm filter, not a 100mm, that I bought. The funnel's outside diameter is measured in millimeters (mm). I'm using a fine screen with a resolution of 1. 875 inch (47.75 cm) Rather than using standard filter paper (which has a diameter of 6mm), you can make your own. You could probably use a 90mm diameter filter paper if the wall thickness of the 100mm filter is similar to that of the 60mm filter. If you're going to filter with vacuum (which I'm not), the filter paper only needs to cover the holes in the bed of the filter, not the entire inner diameter, so an 80mm diameter paper would suffice.
Whatever diameter fits snugly inside the funnel (that is, the same diameter as the funnel's interior surface)
Selected User Reviews For StonyLab Porcelain Buchner Funnel 60 mm, Porcelain Buchner Filter Funnel OD 6 cm ID 5.7 cm for Laboratory
Several holes in the funnel are not drilled/formed properly, as you can see at a glance. The sticker was applied incorrectly, leaving one edge lifted, causing the entire sticker to fall off over time.
according to the description As suggested in other reviews, I went with 90mm filters, which worked perfectly. The only flaw with this porcelain funnel is that the very top lip is unglazed and a little rough, which was most likely caused by the manufacturing process. However, it isn't a serious problem. I would gladly purchase more funnels from this company because they are easy to clean.
This is a great fix if you, like me, screwed up in Chem lab. It's not the kind of quality you'd expect from a multi-billion dollar corporation. The college uses $100 funnels, but this one gets the job done without a hitch. br>br>It does the job, is ceramic, and is reasonably priced.
Poor quality product that appears to be a reject or a generic filter with a label slapped on it. The measurements are also incorrect; as you can see, the stony lab filter paper will not fit!.
It works great because it's just a regular filtration funnel with some filter paper. It's a little rough around the edges, but for the price, it's perfectly adequate for your home chemist.
It works well as a filter holder for our goat milk, as amusing as that may sound. It's a lot faster than the previous method.
Prompt delivery, excellent performance, and no problems after a few uses. This was a good buy.
I'm a graduate student, and I purchased this for our research lab. At first, I was hesitant because we always have to buy equipment from "big providers" to ensure quality and effectiveness. The Buchner funnel, on the other hand, was ideal. I was blown away by it. It is recommended by it is recommended by it.
