Description
Summary:The connection of tubes to a polydimethylsiloxane (PDMS) device can usually not be realised easily. Tube connectors embedded in the PDMS structure have a large foot print. Thick layers of PDMS in which the tubes or needles can hold hinders the visualisation of sample within the device. In this contribution we present microfluidic connectors for PDMS chips realized by easy-to-use elastomeric impression material polyvinylsiloxane (PVS). PVS cylinders were added to a pre-cured PDMS chip and ready to use within five minutes without the need of exposure to high temperatures or the use of additional glues. The robustness of the PVS connectors has been demonstrated through pull-tests and liquid pressure tests.
