Just bought a Ritchie's Acid Test Kit, the same type as Bob demonstrates in post #4 here: http://www.winesathome.co.uk/forum/showthread.php?t=886
Instead of the 5ml syringe they describe in the instructions, they have packed a 2.5ml syringe. I realise that this just means filling the thing with sodium hydroxide more often than with a bigger syringe, but:
- should I be annoyed and ask for the correct syringe?
- should I be be happy that with 1/10ml graduations I can now estimate to 1/10th ppt?
----
Otherwise, the instructions say to use distilled water - I guess I'll have to go and buy some, or, does boiled and cooled water suffice?
(I remember boiled and cooled water was an acceptable alternative to distilled back in the day when it was possible to maintain your own car battery rather than just chucking it and buying a new one).
