APERA LabSen®223 pH/Temperature Electrode for Viscous and Low Ionic Strength Samples

Fiyat Sorunuz

Combined glass pH/Temperature electrode with moving sleeve junction for viscous samples and low ion concentration solutions; includes built-in temperature sensor and long-life reference system.

  • Moving Sleeve Junction — easily cleanable, especially suitable for low ionic strength solutions and non-aqueous solutions. Electrolyte infiltration rate is determined by sleeve tightness during assembly.
  • Long-Life Reference System — consists of glass tube, silver chloride (AgCl), and reference silver wire. The upper end of the thin-walled glass tube is filled with cotton to prevent reaction between AgCl and electrolyte during temperature fluctuations. Enhances reference electrode stability and extends electrode service life.
  • Specialized Glass Membrane — the cylindrical glass membrane offers excellent impact resistance compared to traditional glass bulb membranes and enables testing at elevated sample temperatures (up to 176°F).
  • Built-in Temperature Sensor — enables automatic temperature compensation for accurate pH readings across varying sample conditions.

Frequently Asked Questions

What makes the moving sleeve junction advantageous for low ionic strength samples?
The moving sleeve junction is easily cleanable and allows precise control of electrolyte infiltration rate by adjusting sleeve tightness during assembly. This feature is particularly beneficial for low ionic strength and non-aqueous solutions where minimal electrolyte leakage is critical.
How does the long-life reference system extend electrode service life?
The design incorporates a thin-walled glass tube filled with cotton at the upper end, which prevents unwanted reactions between AgCl and the electrolyte during temperature fluctuations. This significantly enhances reference electrode stability and prolongs the overall service life of the electrode.
What is the maximum temperature for sample testing?
The LabSen®223 can be used with samples up to 80°C (176°F) without compromise to the cylindrical glass membrane's integrity, which offers superior impact resistance compared to traditional glass bulb designs.
Is automatic temperature compensation included?
Yes, the electrode includes a built-in 30kΩ thermistor temperature sensor that enables automatic temperature compensation for accurate pH readings across varying sample conditions.
