You need to buy a drop test and only for sodium nitrite. I bought the Nilpa test - in my country there is not such a large selection of tests. When I bought this test, I was very surprised by the measuring cup - it turns out that 50 milliliters is only twice the size of this measuring cup! 50 milliliters of SN will be very easy to swallow - no matter how bad the sodium nitrite taste is - it is a very small volume. It's a good news.
