Inline filter

The nano pump is equipped with a filter in front of the EMPV.
The standard filter has a volume of typically 100 µl. If the application needs a
reduced volume (e.g. for fast gradient) the 20 µl low volume filter
(01090-68703) is recommended. Be aware that the filter efficiency and
capacity is significantly reduced compared to the standard one.
Never run the nano pump without an inline filter.
