1900 – Used Speedisk 48 Pressure Processor

This used Speedisk 48 Pressure Processor was acquired from a apothecary from the Netherlands who had no need for the system anymore. The system is tested on functionality and everything seems to work with the exception of the manifold pressure gauge, this problem is solved by using an extern pressure gauge which is delivered with the system (see the pictures).

The Speedisk 48 pressure processor is designed to process 1, 3 and 6 ml SPE columns in batches of 1 to 48 samples. The columns are placed under the pressure processor manifold where an inert, dry gas simultaniously and uniformly displaces the liquid that was pipetted down each column.

Advantages Pressure processing over traditional vacuum processing

• Higher pressure differentionals are achievable to overcome resistances to flow caused by high viscosity.
• Gas distribution through the manifolds ensures uniform pressure and uniform liquid flow at each SPE tube. That enables reproducible SPE runs column to column.
• Liquid flow rate changes quickly and proportionatly when gas pressure is changed.
• Blow-down and drying with N2 can be performed in place. An dry, inert gas can be used for processing.
