ISOLABMeasuring Cylinder 25ml - Class A - Tall Form - Borosilicate 3.3 Glass - Conformity Batch Certified - Blue Scale - Pack of 2

The media could not be loaded. I am really liking the ISO Lab glassware that I have recently acquired. This graduated cylinder set is no exception. Despite liking the quality overall, however, I do have one problem with them, and that is the roughness of the glass on the bottom. Please see the accompanying video.The problem is that there is glass flashing that projects from some of the corners on the base. These areas project enough and are rough and sharp enough to cut. This can be taken care of with a bit of very fine sandpaper, but one should not have to do that with new glassware.The glass of the cylinder itself, the graduations, and the finish of the top is excellent.Recommended, but with caution concerning the base. These would be an easy five star rating were it not for the egregious quality control issue with the base.

Laborqualität besser geht es nicht

Prodotto ben fatto, ottimo per dosare i liquidi!

Son de enorme calidad. Vidrio de borosilicato muy grueso. Da sensación de robustez y durabilidad. Es buena compra el conjunto de dos por ese precio. Vienen bien embaladas para protegerlas en el viaje

Het glaswerk zelf is nogal gebrekkig. Met name de beschadiging aan de binnenkant van de tuit maakt het praktisch onmogelijk om deze meetcilinder grondig schoon te maken.
