keeping the whizzinator kit at correct temp

[Burnt Toast]

Question for burnt toast. How long do u think they would keep a bottle b.? Synthetic wont grow bacteria and reg would in a storage type enviroment right?

Mosts synthetics carry a 18-24 month shelf life at room temp.
Synthetics wont grow bacteria. Instead, when the synthetic has reached the end of its shelf life, the urine constituent "buffers" (creatinine, pH, S/G, etc) break down to zero, resulting in a "not consistent with human urine" ruling.
