Where do you guys get your pyrocat HD. I see photographers formulary has a powder kit but it doesn't specify if it is part A and B or if its both together.
Are there any sources for pyrocat HD in premixed liquid form?

Any commercial product will always be a and b separately. Combined it lasts half an hour or an hour or so; it oxidizes very rapidly (which, of course, is its essence!)
Likewise the PF Pyrocat HD in glycol 50 litre kit 01-5093 $36.95 one bottle @ of A & B
If you only process a few negatives per month there is also a smaller 10 liter kit. If you get any cross contamination in part A it will go bad quickly. I had a batch go bad when I mixed up the bottle lids and it would not fully develop using my normal times.
This year, I bought a 10 liter kit and a 50 liter kit. I use the 10 liter kit with dedicated syringes until about half full and then top up from the 50 liter kit. If I somehow cross contaminate the smaller kit the loss is not as much.
You could do the same by using smaller bottles if you have them on hand.
Label your bottles and lids, syringes, and any other labware you use with PyrocatHD and use them the same way every time. You can get label maker tape that is chemical resistant (if you are nerd like me).
Store in a stable temperature controlled environment for best long term use.
The magic you are looking for is in the work you are avoiding.

Good point about cross contamination, I also used a labeled everything with big A’s and B’s to keep things straight and I also decant into smaller bottles from a 50ml kit.

I used to use syringes for PMK pyro but have been using pipettes (bought from a member here) and find them easier to use, of course, ymmv
not sure how they'll work for Pyrocat in glycol though
notch codes ? I only use one film...
Since I mix my own, I only mix 250ml at a time (in glycol) and store in brown glass bottles. I use separate A and B syringes to measure out for development.
