The Multiflux-2 range is optimised for microfluidic experimentation offering a multi-way tubing connection with excellent alignment, low dead volume and high density. Top Interfaces enable connection to ports in the top surface of microfluidic chips and are available for 2mm and 4mm chip heights. H Interfaces enable connection to the edge of microfluidic chips providing a straight fluidic path from tubing to microchannel and are available for 4mm chip heights with 11.5mm, 22.5mm and 45 mm chip lengths. The Triple Top H interface combines surface and edge connections.
