How to test SN using strips?

[jisatsu88]

I got these strips and confused on how to test them.

Test it the way Vizzy did, but with this adjustment. If you go with the method where you add 3.75 grams of SN to the first cup, I recommend first transferring 0.5 ml to the second cup (ideally using a 100-unit insulin syringe, where 1 unit = 0.01 ml), dipping the test strip, then transferring another 0.5 ml and dipping a second test strip. This way, you can make sure you didn't overdo it with the concentration

Who has a 100-unit insulin syringe lying around? Is there anything else that can be used

In my country, I can easily buy regular, insulin, and tuberculin syringes over the counter at pharmacies. To be honest, I don't know what to suggest as an alternative, since syringes seem like the most reliable option to me

I ordered mine from Amazon when I ordered the test strips & other testing supplies.
