Thank you! I’m an idiot for not thinking of the MSDS. Sent from my iPhone, pls excuse typos On Jan 11, 2025, at 3:30 AM, Michał Taube <michalta...@gmail.com> wrote:
Hi Patric, it seems that this is water solution of 0-2% chloramine-T , trihydrate. Happy New Year, Everyone,
I have a question about the “cleaning syringe” that is sold for DI water systems such as the Barnstead Nanopure (when one replaces the cartridge, one injects the contents of this 60-mL syringe into the cartridge and the system then goes through a pre-programmed cleaning cycling).
Does anyone know what’s in this syringe, or have a DIY version?
I’ve always suspected it was something simple like dilute NaOH, but I never bothered to check. However, now they’re becoming hard to get, and so replacing the cartridge is delayed for months while the cleaning syringe is on back-order. They’re also absurdly expensive (70 USD for 50 mL of solution), so it would be great to be able to do a home-brew.
Thanks for any insights.
Pat
