Clog free long lasting junction electrode

Clog free long lasting junction

  • The unique, free-flowing liquid-to-liquid junction offers a stable, drift-free measurement.
  • Easy-to-clean junction that avoids clogging by simply pressing the cap and flushing the junction area.  
  • Sure-Flow junction electrodes are compatible with samples containing organic compounds, proteins, heavy metals, and other compounds that react with silver such as bromides, iodides, cyanides and sulfides.
  • Silver chloride Sure-Flow electrodes can be used on tough samples that do not require a double junction electrode to prevent contact with silver.
  • ROSS Sure-Flows are also available as semi-micro pH and reference half cell electrodes.

The Sure-Flow technology has a lever that allows reference solution to be flushed from a spring-compressed junction. This enables easier clog-free maintenance when measuring difficult samples.

Sure-Flow technology junction press to release
Step 1: Press and hold top of the electrode
Sure-Flow technology spring-compressed junction to flush
Step 2: The spring-compressed junction opens to release fill solution through a ¼ inch gap
Sure-Flow technology spring-compressed junction release
Step 3: When pressure is released from the top of the electrode, the junction closes the gap to a nominal sleeve junction spacing
