TrueRef MilliRef Reference Electrode

Description

Quality Reference Microelectrode

Ag/AgCl reference electrodes, also known as silver/silver chloride reference electrodes, are widely used in electrochemistry to provide a stable reference potential. TrueRef Systems offers miniature 1.5 mm reference electrodes with 3 M KCl for laboratory and small-volume electrochemical setups. Designed for durability, stability, and ease of use, they are well-suited for electrochemical experiments in laboratory setups – especially where space is limited. Their main benefits include:

• Small dimensions (OD 1.5 mm) making them ideal for microfluidic and confined experimental setups.
• Durability and flexibility, ensuring reliable operation even under demanding conditions.
• Low resistance and stable potential, providing accurate and reproducible electrochemical measurements.

Construction

• 5 mm long measuring tip made of chemically resistant PTFE
• 10 cm flexible copper cable with stranded wire core
• Durable plastic handle for easy and safe manipulation
• 2 mm pin banana receptacle for convenient connection

Materials

As the core reference element, we use a high-quality silver wire coated with a uniform AgCl layer, immersed in 3 M KCl solution. The measuring tip of each electrode is made from high-quality, chemically resistant PTFE, providing excellent durability and stability in demanding electrochemical environments. A flexible copper cable provides reliable conductivity and ease of use, while the plastic handle and 2 mm pin ensure a secure grip and connection.
