Thanks to its size, speedwave Entry is particularly well suited to flexible laboratory use. The combination of space-saving design and ease of use makes it particularly attractive for use in routine analysis, training or study. Especially in routine analysis, where large amounts of samples must be cost-effectively digested within tight time frames, there is a demand for microwave digestion systems that don’t need a lot of a…

Synthetic chemistry is seen by some students as a complicated issue. How about changing the perspective? What about simplifying the work of students, teachers and chemists in general?

Solvent extraction with the SER 158 can be performed for extractable matter determination on a wide range of sample matrices either in food and non-food industries (such as pulp, paper, textile, chemical) and for sample preparation. The solid-liquid extraction process removes the soluble components from solids using a liquid solvent. The SER 158 works in accordance to international standards such as AOAC, ISO, EPA, APHA, UNI.…
