• User friendly and convenient

    It is easy to assemble and was engineered to fit with several brands of 6-well plates

  • Multiple confinement experiments simultaneously

    Enables the study of different cells or to apply different confinement conditions at the same time

  • Adaptable with your microscope

    It was designed to fit in your microscope

The CSOW 610 – static confiner is a portable device that allows confining cells within two surfaces with nanometer precision. The space between the two surfaces is controlled by using micro PDMS pillars. The micro pillars are fabricated in a glass slide, which is attached to a PDMS piston. The CSOW 610 is the device that controls the position of the pistons and it is compatible with several brands of 6-well plates.  In the end of the confinement experiments, the cells can be retrieved enabling further biochemical studies. The user decides when and where to confine the cells as it is not necessary to plug it to any other device.

Scheme of the CSOW 610:


The CSWO is compatible with different brands of 6-well plates (Cellvis, Falcon (glass and plastic bottom), Nunc, TPP).


The static cell confiner CSOW 610 kit is composed by:

  • 1 x CSOW 610
  • 12 x Confinement Piston in PDMS
  • 12 x Confinement Slides – 16 mm (diameter) glass slides/cover slips with micro-structures in PDMS (pillars) that enable the confinement

Available confinement heights – from 1, 2, 3, … up to 20 um (you can choose up to 3 heights to integrate your kit)

If you want to make your slides adhesive to your cells or not (optional):

  • Aliquots of extracellular matrix protein for cell adhesion (for example, fibronectin) in the right buffer solution
  • Aliquots of anti-adhesive molecule (poly-ethylene glycol) ready to bind on the slides
