1-Well static confiner – CSOW 110
The static confiner is a portable device that confines cells between two surfaces with nanometer precision. The space between the two surfaces is controlled by using micro PDMS pillars. The micropillars are fabricated on a glass slide, which is attached to a PDMS piston.
The CSOW 110 is the device that controls the piston
> User friendly and convenient
It is easy to assemble and is portable
> Enables high resolution imaging
It fits with glass bottom petri dishes (35 mm) and the observation area is made of optically transparent materials
> Adaptable with your microscope
It was designed to fit in your microscope
> HOW TO USE THE CSOW110
> THE STATIC CELL CONFINER CSOW 110 IS COMPOSED OF:
1 x CSOW 110
2 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 µm (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
If this device does not meet your needs, get in touch with us! We can personalize it for you.

Overall dimensions of the CSOW 110
The lid enables access to the petri dish, allowing cell media to be exchanged while cells are confined.
