Syringeless filter device compressor

A syringeless filter device compressor comprising:

• a support structure;
• a compression means connected to said support structure and capable of moving with respect thereto from a first position to a second position;
• an actuation means for actuating said compression means to move from said first position to said second position;
• a syringeless filter device holder configured to hold a plurality of syringeless filter devices in a corresponding plurality of predefined positions forming a two-dimensional array, wherein said syringeless filter device holder comprises a plurality of gaps in a side wall and a top surface having a plurality of recesses capable of holding said plurality of syringeless filter devices, each said gap extending from said side wall to a said recess, whereby at least a part of an interior surface of said plurality of recesses is visible through said plurality of gaps;
• and
• a transparent seal locatable in said plurality of gaps, wherein said transparent seal is configured to inhibit fluid passing from said plurality of recesses to an exterior surface of said syringeless filter device holder,
• wherein, when one or more syringeless filter devices are held in said syringeless filter device holder, actuation of said actuation means results in a first part of said one or more syringeless filter devices moving towards a corresponding second part of said one or more syringeless filter devices.
