Hi We are trying to develop a microfluidics flow chamber for biological application. We require the smallest possible interfaces to the microfluidics chip. We are trying with capillary tubes but that presents several problems with leaking. We also saw microfluidics ports from upchurch but their outer diameter is too big (8mm) and doesn't allow us to do microscopy. Does anyone know about small interfaces to the microfluidic world? Thank you very much in advance Ciro Chiappini Graduate Research Assistant Biomedical Engineering - University of Texas at Austin Dr. Mauro Ferrari Nanomedicine group
