Optimize Technologies Opti-pak 5.0 Ml C18 Pk5 10-03233-TF FREE S&H . Optimize Technologies High pressure liquid chromatography HPLC columns.

The Opti-Pak is specially designed for use in today's low volume applications The unique hardware design integrates a PEEK holder with an auto-adjusting stem which provides a fluid interface with any 10-32 standard or microinjector port, and guarantees a zero-dead-volume connection despite variances in tubestop depth. Installing an Opti-Pak into the outlet of a switching valve will facilitate the trapping, desalting, and pre-concentration of an analyte mixture. With Opti-Pak's versatility, a second trap can be added downstream in the loop of an injection valve and effectively perform a 2D separation. The elegant, flexible design of Opti-Pak makes it amenable to virtually any trapping application. Opti-Pak can be installed directly into the fitting port of an injection valve. Two or more Opti-Paks can also be installed side by side in the same valve stator without interference. With bed volumes ranging from 0.12 L to 5.0 L, you can find the perfect balance between sample capacity and trap volume. A proprietary method of frit placement allows the packed stem to be positioned directly into the flow path, which eliminates all excess swept volume. Less swept volume translates to absolute minimum sample dilution and dispersion.
