standard ground stoppers
Hollow glass stoppers, type C, borosilicate glass 3.3
The hexagonal LABSOLUTE® hollow glass stoppers with standard ground joint and pointed bottom are made of high-quality borosilicate glass 3.3 and are therefore extremely temperature-resistant up to 500 °C. The stoppers comply with DIN 12252 form C. They are resistant to cold lyes/alkaline solutions and strong acids with the exception of hydrofluoric acid and concentrated, hot phosphoric acid. The stoppers can be easily combined with all glass products that have a ground joint such as measuring flasks, Erlenmeyer flasks or round bottom flasks....
NS-Glass stoppers, hollow borosilicate glass 3.3
Hergestellt aus Borosilikatglas 3.3, das gegen Hitze und fast alle Chemikalien beständig ist. Sie entsprechen den höchsten Qualitätsnormen nach DIN 12252. Das untere geschlossene Ende des Stopfens verfügt über eine "Abtropfspitze", die dafür sorgt, dass anhaftende Flüssigkeit in den Kolben zurück gelangt. Die flache sechseckige Platte verhindert, dass der Stopfen wegrollt und lässt sich als Standfläche benutzen, um eine Verunreinigung der Arbeitsfläche zu verhindern....
