**PDMS is the most widely used silicon-based organic polymer, and is particularly known for its unusual rheological (or flow) properties. PDMS is a rubber like elastomer, optically clear, and, in general, inert, non-toxic, and non-flammable. PDMS chips are the most used platforms in Microfluidics.

**Since PDMS parts have rubber-like mechanical properties, they are not stiff enough for handling especially when the parts are less than 1 mm (0.04”) thick. Therefore, these PDMS parts are often bonded to glass microscope slide or thin glass cover slide, or even custom size glass substrates. Sufficient bonding strength between PDMS and glass is needed for continuous flow applications, otherwise the fluid would leak out of the microfluidic device. uFluidix has special expertise in bonding and sealing PDMS parts to glass and variety of other substrates for the manufacture of microfluidic chips.
