StepSaver streamlines the extraction process by allowing the analyst to collect the solvent with eluted oil and grease directly into a collection flask. As fluid enters the collection flask, it passes through a drying cartridge to remove excess water. It is ready to be evaporated without a separate drying step.

UltraFlow disposable polypropylene filter funnels come with preinserted SPE filter disks. Filter disks are constructed of two layers of glass fiber filter material. The top layer acts as a prefilter while the bottom layer is bound to a high carbon C-18 adsorbent. This laminar construction results in a product with a high flow rate and higher dirt holding capacity than other SPE products.
