Presto Accelerated SPE System
What is the Presto accelerated SPE system?
The Presto is an 8-channel automated SPE system engineered for large-volume samples at high flow rates. Newly integrated continuous pumps load a 1 L sample in about 20 minutes using SPE Mini-disks or other compatible cartridges and disks. Compact and robust, it is the most efficient SPE system for large-volume or high-particulate environmental samples.
How does the Presto handle difficult, high-particulate samples?
The Presto is built for matrices that clog conventional SPE:
- Continuous pumps for swift sample loading and strong particulate resistance
- Individual flow control for each sample line — any line can be disabled
- Pressure monitoring and flow correction that adapt to matrix variation, with cartridge pressure warnings for safety
- Empty-line detection that alerts on premature depletion from clogging, leakage or tubing placement, and stops loading on channels that have finished
Which samples and methods is the Presto used for?
The Presto targets large-volume and high-particulate environmental samples — drinking water, waste water, surface water, sea water, leachate and more. It automates extraction of 100+ SVOCs following EPA Method 525 using Mini-disks in under 80 minutes. It has been beta-tested for TCLP semi-volatiles in leachate (Merit Labs) and brevetoxins in sea water (Mote Marine Lab).

Frequently asked questions
Can the Presto process large-volume water samples quickly?
Yes. Its continuous pumps load a 1 L sample in about 20 minutes using SPE Mini-disks, and it automates extraction of 100+ SVOCs per EPA Method 525 in under 80 minutes.
What sample volumes and column sizes does the Presto support?
0.5–4000 mL per sample across 8 parallel channels, with 1/3/6 mL or 6/12/20 mL SPE columns and up to 7 solvents.
Is the Presto suitable for high-particulate or dirty samples?
Yes. Continuous pumps, pressure monitoring with flow correction, and empty-line/clog detection make it the most efficient choice for high-particulate matrices such as waste water, sea water and leachate.
Which environmental samples can the Presto extract?
Drinking water, waste water, surface water, sea water, leachate and more. It has been beta-tested for TCLP semi-volatiles in leachate (Merit Labs) and brevetoxins in sea water (Mote Marine Lab).
