Perspective view of a Philips cup

A Philips beaker is a simple glass device for various purposes in (scientific) laboratories. It is understood to be a beaker that is conically narrowed towards the top and has a flanged edge and usually a spout. The shape of the Philips beaker lies between the beaker and the Erlenmeyer flask .

The Philips cup is mainly used for viscous liquids.

Different spellings of the name

In the literature from the 19th century the laboratory device is written like this - with reference to an even older textbook by Faraday: "Phillips cup". In more recent publications you can find the spelling "Philipps-Becher". A current chemical dictionary, however, calls the laboratory device "Philips beaker".
