It combines filtration and storage into one simple device that can be integrated with the PAL. They currently come with 2 pore sizes and many different [http://www.whatman.com/MiniUniPrep.aspx#UN203NPUNYL filter media]. They are designed for manual operation but are not conducive to large batch sizes - repeated pressing by hand being very fatiguing. <br> Mini UniPrep Syringeless Filters are specifically designed to remove particulates from smaller sample volumes. Mini-UniPrep consists of a 0.4 ml capacity chamber and a plunger. The plunger contains a filtration membrane at one end and a pre-attached cap/septum at the other. The plunger is pressed through the sample in the outer chamber and positive pressure forces the filtrate into the reservoir of the plunger. Air escapes through the vent hole until the locking ring is engaged providing an air-tight seal. ''(see Diagram)'' |

| + | LEAP has developed a "Press" accessory,'''LEAP X-Press''', for the PAL which allows samples to be filtered reliably and repeatably. It does not require external pneumatics, but compress the filter chambers. Samples can be processes in batch mode or "just in time" before direct injection to the LC valve. The LEAP X-Press can be used for stand-alone operation with an optional foot. | ||

The LEAP X-Press can be used for stand-alone operation with an optional foot.
The PAL offers precise control of the down force on the sample. The user can specify the speed of compression in the method, allowing even very heavy suspensions to be filtered successfully.
The complete system can provide automated online filtration, including sample preparation, sample transport and injection into the chromatographic system.
