Vingerzuiger

Vingerzuiger is the article on this page. Luminix Health distributes Kummer for laboratory use. It sits in Beaker & flask accessories, inside Beakers & flasks, in Laborbedarf.

Accessories for beakers and flasks are the cork rings, the covers, the joint clips and the holders that keep a flask upright or closed. A clip is what stops a ground joint from falling apart when it is inverted.

A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.

The category is Beakers & flasks. The sub-category is Beaker & flask accessories. The catalogue is Laborbedarf.

Shelves beside this one are Round-bottom flasks, Beakers, Erlenmeyer flasks, Reaction vessels & jacketed vessels, Flat-bottom flasks and Flasks (other).
