High-precision, non-contact picoliter and nanoliter dispensing has never been easier than with the iFOUR from M2-Instruments. The microdispensing instrument for diagnostic and pharmaceutical research dispenses small volumes on a freely configurable workspace. Numerous applications can be supported with a range of dispensers and tips, including filling of Microcavities; Multiplex Immunoassays; Protein, Aptamer and DNA microarrays, Cell dispensing and more. A world first is the integrated "Puls Shaper" module, which quadruples the single-drop volume range without affecting the frequency. This allows the iFOUR to dispense a wider range of liquid viscosities.
