Nice, thanks for the link. The McMaster filter is identical to the Neptune other than Barb size. If it’s easy enough open I’ll try it on the Neptune. But now that I think about it surely if Hanna makes the discs they make the filter?

Or, you take a pair of scissors and cut the tip at an angle.
Then you can slide the 1/16" ID tube over the 1/8" OD barb.

Looks like a good solution there. Just a pro-tip regarding filters since I have quite a bit of experience validating filters just like these for use in pharmaceutical manufacturing - since that replacement is probably a larger membrane and with potentially different materials of construction than the original, it would be a good idea to flush the filter out with 10-20 mL of RODI and then prime with saltwater before use. Filters like this have quite an extensive leachables profile, which may or may not contain compounds that could interfere with the test results. A good pre-use flush will remove them to be safe.
And there it is folks! Many thanks!Or, you take a pair of scissors and cut the tip at an angle.

Did this end up working well once you started taking measurements? I’m going to order some unless you’ve experienced any issues since the original fitment.Or, you take a pair of scissors and cut the tip at an angle.

I did end up using it. It's too soon to know if it's better/worse than the original, but it works fine so far.
