Central extraction units can not only reduce cleaning-, energy- and maintenance costs but - more importantly- noticeably improve the working environment. You can optimise the working processes using a central extraction unit. Production residues such as smoke, dust and vapour are reliably removed right away.The Liquid-Liquid Extraction Unit, "UELL", is a laboratory scale unit designed to study the separation of the components of liquid mixtures by contact of the mixture with an immiscible solvent in which these components are preferentially soluble.
