He invented the Soxhlet extractor in 1879 and in 1886 he proposed that pasteurization be applied to milk.
2.
Techniques used include atomic absorption, spectrophotometry, selective electrodes, pHmetro, conductivity, Soxhlet extractor, and the Kjeldahl method.
3.
The thimble is surrounded by hot solvent vapour and maintained at a higher temperature compared to the Soxhlet extractor, thus allowing better extraction for compounds with higher melting points such as bitumen.
4.
A minor use is in some types of Soxhlet extractor, where a concentric siphon is noted in advertising material as being more robust and having a lower volume than a U siphon.
5.
Very similar to the Soxhlet extractor, the Kumagawa extractor has a specific design where the thimble holder / chamber is directly suspended inside the solvent flask ( having a vertical large opening ) above the boiling solvent.
6.
The material produced was 35 % Cu 4 O 3, 27 % Cu 2 O, and 38 % CuO . The process consists of the leaching of copper or its oxides with concentrated aqueous ammonia in a Soxhlet extractor.
