Hanna Checker Vial Thread Size

[Bradyhall805]

I was trying to make a drying rack for my Hanna Checker vials and was having a hard time finding the thread size for them. I tried calling Hanna and spoke to their tech department and they didn't know what the thread size was either. Any help would be much appreciated and thank you for your time!

Probably 22-400 as this is a standard size for such vials. 22 is the distance from the outside of one thread to the opposite one. 400 refers to the thread type. See below for explanation.

Thank you for that information. That helps a lot and was exactly what I was looking for. Didn’t even know they made different threads for glass and thought it would be a standard or metric thread.

Thank you,
Brady

Good luck - I hope this works for you.

Thank you! I was able to find the specs for the threads from the diagram you sent and what you said. Unfortunately CAD does not have API threads in their system, but after a lot of messing around I was able to create a custom thread in a couple different CAD programs and load it into Fusion 360. Just did a test print and it looks like they are holding great with those threads. Thank you again for the help!

Is this the new Hanna test vials or the old ones used in the individual kits? My wife put them in the dishwasher and now I need all new caps.
