Kofler bench

Any substance can be placed on a section of the strip revealing its thermal behaviour at the temperature at that point.

[2] The gradient is engineered to be approximately linear.

[3] This melting-point apparatus for use with a microscope was developed by the Austrian pharmacognosist Ludwig Kofler (30 November 1891 Dornbirn - 23 August 1951 Innsbruck) and his wife mineralogist Adelheid Kofler.

[6] Kofler, his wife Adelheid, and their colleague, Maria Kuhnert-Brandstätter, investigated numerous organic molecules, and published some 250 papers describing their work.

[7] Thermomicroscopy, incepted by Ludwig and Adelheid Kofler and developed further by Maria Kuhnert-Brandstätter (1919–2011) and Walter C. McCrone used the technique for studying the phases of solid drug substances.
