Heathrow Scientific HD20630D pipetzuigbal, rubber, inhoud 60 ml, rood

Va me servir comme vide siphon, après adaptation.

Fein

As described perfectly

It’s good.

The description should say that the hole diameter is 4 mm and so will only fit the thinnest pipette. It certainly doesn't fit the 10 ml pipettes which generally have a 9-10 mm diameter neck.
