• Define the thickness and shape of cells 

    Control the thickness of your cells with the right confinement slide

  • Multiple experiments simultaneously

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

  • Adaptable with high resolution microscopy

    Optically transparent materials and compact design enable high resolution microscopy

The CSOW 620 – 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 620 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. In particular, the CSOW 620 is characterized by its compact design and CO2 plug.

Scheme of the CSOW 620:


The static cell confiner CSOW 620 kit is composed by:

  • 1 x CSOW 620
  • 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
