3S is an intelligent packaging solution protected with an originality seal. The cap provides information via Radio-frequency identification or RFID, enabling automated data transfer between the reagent and titration instrument. Intelligent communication for improved performance.

Titration on a new level—wet chemical analysis is made safer and more reliable by 3S Adapter Technology:

  • Safe chemical handling: minimized risk of contamination through contact-free reagent exchange
  • Smart connection of chemical consumables: communication between the 3S cap and instrument software via RFID with a visual status indicator on the system
  • Secure information transfer: Direct RFID-based transfer of reagent data to instrument software for elimination of human error.

3S Reagents are compatible with Metrohm’s OMNIS titration platform through 3S Adapter Technology.

What is 3S?

  • Safe, Smart, and Secure
  • Ready-to-use volumetric solutions sealed with 3S caps
  • RFID-chip on the cap with complete information about the content of the bottle
  • Absorber cartridge integrated in the cap

Benefits for You

  • RFID-based identification of reagent—automated and error-free
  • Complete traceability of the analyses provided
  • Aspiration tube already integrated into the bottle
  • Unique opening procedure minimizes risk of contamination
