Cole-Parmer Extended-Life Conductivity Standards

Control the expiration date of your conductivity standards
  • Shelf life up to 5 years in the special storage envelope, or 1 year after opening — whichever comes first!
  • NIST-traceable calibration report from an ISO 17034 and ISO 17025 accredited laboratory included with each bottle Note: 1uS = 1Mhos
Transpiration (evaporation) often limits the shelf life of conductivity standard solutions. These solutions ship in a special metal-lined envelope to extended shelf life—up to 5 years! The envelope is clearly marked with the 5-year expiration date from the date of manufacturer. When ready to use, simply open the sealed envelope and begin the 1-year shelf life. Both the bottle and Certificate of Analysis have a convenient marking area to write the new expiration date—putting you in control.
Store at room temperature. One 17-oz (500-ml) bottle. Additional values and packaging sizes are available; call for details.
