Oil and Grease EPA 1664

Solid Phase Extraction Made Easy

The patented StepSaver for solid phase extraction saves time and simplifies EPA Method 1664 for Oil and Grease.

The StepSaver streamlines the extraction process by allowing the analyst to collect the solvent with eluted oil and grease directly into a collection flask eliminating the need to disassemble or reassemble glassware. As the eluent enters the collection flask it passes through a drying cartridge to remove any excess water so it is ready to be evaporated without a separate drying step. It's easy and efficient. After activating the filter, pour your sample into the funnel and attach a vacuum source. Turn the stopcock to allow the sample waste to pour off into the waste carboy. Close the stopcock and add n-Hexane to elute off the oil and grease. Turn the stopcock the other direction to allow the n-Hexane to pass through the Na2SO4 drying cartridge and into the pre-weighed collection flask. Your sample is ready to be evaporated.

StepSavers come in several configurations. Choose the funnel type, manifold material and number of stations that best suits your lab.

Funnel Types

• Reusable 1000mL glass funnels that you use with individual UltraFlow filters
• Disposable 250mL polypropylene filter funnels that come with the UltraFlow filters already in place

Manifold Types

• PVC manifolds come in 1, 3 or 7 stations
• Stainless Steel manifolds come in 1, 3 and 6 stations
