SN semi-quantitative testkits

[Fakefriendhate_Maxx]

Hey community !! I need your experiences with SN testkits (aquarium nitrite kit, or maybe others too...) Which one can you recommend for testing the purity of my SN ?!

Would be nice, when you have some links and shipping is from EU c:

Thanks in advance !!

I admit that i don't think much of these test kits.
If i have bought the sn from a good source and also have the CoA from it then i don't need to test it.
Then I trust the product and the producer.

Besides, you have to open the container for the test and SN comes into contact with oxygen and light.

This could affect the quality.

Or you can do a quick blood test before you use the sn. prick your finger and put some blood in a very small amount of SN.
If it gets dark quickly, this should also be sufficient as a test.

Thxx it's a good idea with the blod drop.
