Focustronic bulk replacement parts thread (Mastertronic / Alkatronic / Dosetronic)

I have one and am looking for the same. Needles are still not easy to find. I bought the punch and sheet from the earlier pages but am still waiting on the silicone mat.. that's actually not the easiest to find either. Looks like it ships from china.

This is what I ordered last year, has worked out great for me. I changed the silicone seal every time I refill the reagents.

Anyone have a source for the correct PTFE-lined silicon sheets for making septas?

Or maybe this is easier... can someone confirm these would work?

I have a pack of these that I've been using. https://www.aliexpress.us/item/2255800016203486.html

Vent Needles seem to be clogging more often than when I used the plain silicone ones. But the silicone also seemed to break down on a couple of the reagents. Also, I put mine in with the ptfe side facing the reagent, maybe it needs to be the other way around?

Thinking about pulling the trigger. Tagging along.
