<strong>SRD</strong>-<strong>3x00</strong> <strong>Solvent</strong> <strong>Racks</strong><br />
• In an <strong>UltiMate</strong> <strong>3000</strong> system, some components are made of PEEK. This polymer has<br />
superb chemical resistance to most organic solvents. However, it tends to swell when in<br />
contact with trichlormethane (CHCl3), dimethyl sulfoxide (DMSO), or tetrahydrofuran<br />
(THF). In addition, it is attacked by concentrated acids, such as, sulfuric acid and nitric<br />
acid or a mixture of hexane, ethyl acetate, and methanol. Swelling or attack by<br />
concentrated acids is not a problem with brief flushing procedures.<br />
• Before switching from buffer to organic solution, rinse the system thoroughly with<br />
deionized water.<br />
• When switching to another solvent, ensure that the new solvent is miscible with the one<br />
contained in the system. Otherwise, for example, the pump can be damaged by<br />
flocculation.<br />
• After operation, rinse out buffers and solutions that form peroxides.<br />
Important: Neither recycle the solvent nor use methanol from aluminum<br />
reservoirs. This may impair the performance of the seals.<br />
Important: Thermo Fisher Scientific déconseille de recycler les solvants. Ceci<br />
peut nuire aux performances des joints.<br />
