SPE Columns<br />

• Open top tubes with male luer bottom<br />

• Process multiple samples with vacuum manifold or automated SPE instruments<br />

• Process individual samples manually with use of adapter and syringe<br />

Traditionally, differing nomenclature has been used to<br />

describe SPE column size. Sometimes columns are<br />

described in terms of full volume. Alternatively, the volume<br />

above the bed weight may also be used. Below is a crossreference<br />

for your convenience.<br />
