stonylab Glazen Poedertrechter met Korte Steel en 100 mm Buitendiameter aan de Bovenzijde en 14/20 Binnenste Gezamenlijke Filtertrechter Glazen Trechter

I was looking for a funnel that was made of glass because I transfer cosmetic mixes into bottles. I wanted something that I could sterilize and would not react with the chemicals I use. Excellent item and prompt service. Will order from StonyLab if the chance arises again.

Primarily used to fill 2&3 necked boiling flasks with powder liquid or prills. It works well.

Schön und gut.

Conforme à la description et arrivé rapidement, c'est une habitude les produits Stony lab sont de très bonne qualité, rien n'y adhère, facile à nettoyer à l'eau distillée, convient parfaitement à des synthèses de solvants. C'est un très bon produit.

Feels solid and of good quality no imperfections in the glass work. Haven't used yet but will be exposed to cold and hot temps. So as for how shock resistant it is I don't know.
