The SPE-Express system is specifically designed for the extraction and evaporation required by EPA Method 1664 for Oil and
Grease Analysis.
SPE-Express is the ONLY system that:
• Both extracts your sample and evaporates the n-Hexane eliminating the transfer step
• Uses a fluid sensor to verify that the sample vessel is empty improving accuracy
• Runs multiple samples simultaneously on up to 6-stations improving analyst efficiency
Simply load the 3-station SPE-Express with standard one-liter sampling jars and walk away. The system flushes itself clean,
preps the extraction disk, then filters and extracts the sample through sodium sulfate with n-Hexane. In the final stage the
SPE-Express automatically transfers the extract to a pre-weighed aluminum pan where it is evaporated to dryness. Remove
the pan for final weighing and the process is complete. User-friendly PC software controls the functionality while recording
data for downloading to LIMS.
SPE-Express is the only system that both extracts your sample and evaporates the n-Hexane. And the only one that utilizes a
fluid sensor to verify that the sample vessel is empty. It will reduce time and labor in your lab, improve accuracy plus
minimize analyst contact with hazardous chemicals.
