How to easily interface peristaltic and rigid microfluidic tubing
- 21 May, 2019
During your microfluidic experiments, and more particularly when working with peristaltic pump, you may face an issue when trying to connect a peristaltic/soft-walled tubing (for example in silicone) and a rigid tubing (in PTFE, PEEK...).
To ease the interfacing between these two types of tubes, we are using the Peristaltic Tubing Adapter for 1/16" OD PTFE Tubing.
Compatible with soft-walled tubing from 1.20 mm to 3.80 mm, it ensures a leak-free connection with the minimal internal volume possible.
The standard rigid tubing connection is for 1/16" OD tubing, but you can use any 1/4"-28 fitting for other tubing sizes.
Interfacing soft-walled and rigid tubing
To interface your peristaltic/soft-walled tubing with PTFE or any other rigid tubing, just select the "small" or "large" adapter based on the inner diameter (ID) size of the soft-walled tubing (more informations on the product page).
Just connect the soft-walled tubing to the main conical connector (see below, middle). In the meantime, connect the rigid tubing to the fitting and ferrule (left of the image below).

Once done, just screw each part: that's it!
Final adapter assembly
Are you working with other rigid tubing sizes? You can replace the 1/4"-28 to 1/16" OD fitting and ferrule for rigid tubing by any other 1/4"-28 connector. Check our Fittings & Connectors collection to find the suitable adapters for your tubing!
