AppliSens DO Sensor Membrane Kit Z110000425--for replacing sensor membrane

Description

AppliSens DO Sensor Membrane Kit Z110000425.  This kit is complete and unused.  It has all 4 membranes, 4 o-rings, and an unopened bottle of electrolyte.  I have no way of knowing if the electrolyte is still good, however. Sale is "As-Is."  Product as shown in photograph.
From the manufacturer's website:
The AppliSens DO
2
-sensor is specifically designed for long-term, stable and accurate measurements in bioprocesses.
The DO
2
-sensor has a titanium membrane module to minimize the measurement drift. The autoclavable polarization module allows polarizing of your DO
2
-sensor while autoclaving your bioreactor system, resulting in a reduced start-up time of your cultivation.
