Funnel Flask Cones
Adapter Set

  • These filter adapter cones are made of durable vulcanized rubber, characterized by good elasticity, a smooth surface, and resistance to wear.

  • These filter adapter cones are suitable for a temperature range from 0 to 70 degrees Celsius. Please note that exceeding this temperature range may cause the rubber cones to melt.

  • These rubber adapter cones are not suitable for contact with acids, alkalis, and corrosive agents. To ensure their lifespan and experimental safety, avoid exposing them to these chemicals.

  • Select the appropriate Buchner funnel and vacuum filtration flask based on the inner and outer diameters of the filter adapter cones to ensure a good seal before proceeding with the filtration operation.

  • When in use, avoid high temperatures and keep away from chemicals; when not in use, store the product in a dry, cool place, away from direct sunlight and excessive moisture.

Used for vacuum filtration and made the needed seal. It was nice have multiple size options to use.

This set fits many sizes. I used it to fit a 500ml Buchner into a 1000ml, heavy-walled vacuum flask. The issue I had is the material used in the adapter absorbed some of the filtered material and became discolored. Since I plan on using this setup exclusively for the same material, its not a issue for me but may be for general lab usage. If that's an issue for you, I'd suggest finding a set using a different material.

I use these for the repair of vintage camera lenses, much cheaper than actual lens cones!

Ich nutze die Adapter in meinem Minilabor zur Erstellung von pythotherapeutischen- und Mikroskoppräparaten, zB zur Vakuumfiltrierung mittels Buchner-Trichters und einer Vakuumpumpe.Fazit: machen wofür sie konzipiert wurden, guter, sicherer Verschluss und sinnvolle Abstufung innerhalb des Sets. Preis/Leistung ok. Empfehlung.

Lijkt goed, en volgens verwachting, maar nog niet getest in de praktijk. De rubber kraagjes lijken mij gelijksooortig, aan de kraagjes die ik in vroeger tijd, als student gebruikte op het chemisch lab. Dat geeft me vertrouwen in het produkt. Het lijkt me professionele kwaliteit te zijn.
