Questions & Answers

What is the shelf life on these membranes?
5775 DO membranes have an essentially unlimited shelf life as long as they are not stretched, scratched or otherwise damaged. Once they are installed on the probe, YSI recommends replacing them every 2-8 weeks depending on usage. The electrolyte solution arrives as a dry powder with an unlimited shelf life. Once mixed however, it has an expiration date of approximately two years.
