Can the standard IntelliCAL™ pH probes be used with TRIS buffers?
IntelliCAL™ pH probe TRIS compatibility
No, both the gel filled (standard and rugged) and refillable IntelliCAL™ probes have a silver/silver chloride reference. These would not be TRIS compatibile and will result in inaccurate pH measurement due to precipitation of the silver. A Red Rod IntelliCAL™ probe would be required for use in TRIS samples.
