How to Take CDS Wherever You Are and Not Lose Any Strength

Hi and thanks for the video  It looks a great idea but I just have 1 question  Is storing the CDS in a syringe OK as regards contamination from the syringe materials  I note that elsewhere you state thst you store CDS in glass containers  

Thanks

Glass is best for long-term storage, but for this purpose, the storage time is a few hours. 

If you buy CDS, it usually is packaged in a plastic bottle. 

For this syringe dosing idea, the component that could cause a problem is the syringe plunger piston, the black natural rubber seal. It will be damaged if in contact with 3000ppm CDS after a few hours. So, one answer is to use a syringe with a silicone O-ring seal. There are also syringes without any special piston seal. I have some on order to check them out. They might leak.
