The Dolomite Centre LtdDesign GuidelinesIn order to design a compatible PDMS device for use with the PDMS Chip Interface, it isnecessary to follow 5 simple steps:1. Decide if you require 4 fluidic connections or 8 fluidic connections.a. 4 connections can be made with one PDMS Chip Interface and one LinearConnector 4-way. Two chips can be mounted to each slide.b. 8 connections can be made with two PDMS Chip Interfaces and two LinearConnectors 4-way. One chip can be mounted to each slide.2. Decide if your device length fits onto the standard 50 x 25 mm slide or if yourequire the longer 75 x 25 mm slide.3. Design pad features in PDMS (recommended Ø1 mm) at a pitch of 3 mm to alignwith Ø0.5 holes in glass slide. These are the inlet and outlet ports.4. Design outer dimensions of PDMS device ensuring that the boundaries are withinthe maximum width and length specified.a. Maximum width is 15 mm. The maximum distance from outside port toPDMS side edges is 3 mm.b. Maximum length depends on the number of fluidic connections (step 1)and the slide size selected (step 2). The maximum distance from inlet andoutlet ports to PDMS back edge is 3 mm.5. Design channel features in PDMS ensuring that all features to be viewed arepositioned at least 3 mm from the inlet and outlet ports. Visible features should beoutside of the red box in the diagram below.PDMS_chip_interface_product_datasheet Page 8 of 12
