PTFE tubings are standard tubings to connect pumps with the microfluidic chips, so that you can either fill the chip with liquid or remove it from your device. You can connect these tubings with the microfluidic chip via a silicone sleeve in which you insert the PTFE tubing. This silicone sleeve you can either mount on the olive of a Mini Luer fluid connector or directly on olives integrated in your chip.
You use silicone tubes to connect hard plastic tubes like PTFE tubings with pumps or your microfluidic chips and the respective interfaces. You can mount the silicone tubes we offer on the olives integrated in your chips and on the olives of the Mini Luer fluid connectors.
