If you encounter any of these issues, the silicone seals might be leaking. Thus, you must replace the tubing block and/or the chip base seal. Follow the tutorial below to fix the leakage.
Open the chip cover and remove the filter chip.
Check the silicone seals on the tubing block and on the base chip under the chip cover. Make sure the seals are not torn or detached.
OPTIONAL: The µPULSE device includes a spare tubing block and a replacement seal for the base chip seal. If the seal is broken, replace them with the new ones.
A Tubing Block Spare and Replacement Seal
Reload the chip and make sure the chip position fits the inputs, and then close the chip cover.
Run the µPULSE instrument. If the problem persists, please contact support@formulatrix.com for assistance.
