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.…

Benchmark's new IsoBlock dry bath is ideal for incubation of samples at two different temperatures, in a single compact unit. The two chambers are separated by an insulated wall and are controlled independently, allowing IsoBlock to serve as two dry baths in one. The hinged (and removable) lid is also designed with a dividing wall. When closed, this dividing wall acts as a barrier, preventing air transfer between chambers.

Even for LC columns that claim to be designed for basic compounds, adequate resolution often can not be obtained due to problems such as leading of highly polar basic compounds, peak shape deterioration of acidic compounds, or long equilibration time required for low ionic strength acidic mobile phase. All of these issues have been solved with Shim-pack Arata that was specifically designed to give unmatched peak shape for basi…
