Am looking for a solvent check valve to fit onto a teflon line [ 1/8 th inch ] that will prevent solvents from going back to the mobile phase bottle when priming a pump that sits low compared to the mobile phase container .
All help gratefully accepted.

Apparently something like this exists in standard online fitting style housings,

though I must say, I would think any kind of flow restriction on solvent lines would be undesirable, especially with low hydraulic head.

Found a check valve that will do this admirably.
