Top 5 Positive Customer Reviews for flask funnel
It’s a bit crooked. I had to turn it to to one special point where it is nearly straight, but anyway, the finish of the Glas connection is top and seal. The glass is stable and the frit is great and works. Best price for high quality. Top seller - very fast delivery!
Faster shipping. Very nice funnel. No bubbles visible. Good, clean workmanship. I like buying from this seller, he always has good merchandise at reasonable prices. So good price / performance ratio. I'm very happy with the funnel. Only the hose is there is a bit too thin. But my vacuum pump has a hose thick enough that it does not contract. Gladly again . A satisfied customer.
