Extraction kits with optional ceramic homogenizers feature salts for buffering of samples.

• The buffered extraction salts are amenable to more labile pesticides
• Choose the extraction salt type based on your method of analysis: AOAC or EN
• Ceramic homogenizers break up salt agglomerates, promoting consistent sample extraction and increasing product recovery during extraction and dispersion

QuEChERS salts and buffers are prepackaged in anhydrous packages. This allows you to add them to the sample after the solvent, based on your method of analysis (AOAC or EN). Extraction kits include: 50 polypropylene centrifuge tubes (50 ml) with caps, MgSO₄, NaCl, or other salts for buffering. Extraction kits can also be purchased with ceramic homogenizers. These provide consistent grinding of the material being homogenized and can minimize variation. Kits featuring ceramic homogenizers are marked with a CH.
