pH Electrode APERA LabSen®221 for Low Ion Concentration

Fiyat Sorunuz

Routine combination pH electrode with certified Swiss sensor technology, designed for viscous and low ion concentration samples; ideal for titration applications with TRIS buffer compatibility.

  • Mobile Sleeve Junction — easily cleanable, specifically suited for low ion concentration solutions and non-aqueous samples; electrolyte infiltration rate controlled by junction sleeve tension during setup
  • Long-Life Reference System — comprises glass tube, AgCl, and reference silver wire; upper end sealed with cotton to prevent AgCl-electrolyte reaction during temperature fluctuations; enhances reference electrode stability and extends electrode service life
  • Durable Cylindrical Glass Membrane — significantly more impact-resistant than traditional glass bulb membranes; capable of testing high-temperature samples up to 176°F (80°C)

Frequently Asked Questions

Is the LabSen 221 electrode suitable for non-aqueous solutions?
Yes, the mobile sleeve junction design makes this electrode ideal for non-aqueous and low ionic strength solutions, with electrolyte infiltration rate controllable during setup.
What is the maximum temperature the electrode can withstand?
The electrode can be used for pH measurement in samples up to 80°C (176°F), thanks to its durable cylindrical glass membrane design.
Is the LabSen 221 compatible with TRIS buffers?
Yes, the electrode is fully compatible with TRIS buffer solutions commonly used in laboratory titrations and pH calibrations.
What makes the cylindrical glass membrane superior?
The cylindrical glass membrane is significantly more impact-resistant than traditional glass bulb membranes, providing greater durability and longer service life in routine laboratory use.
How does the long-life reference system extend electrode life?
The reference system design with cotton sealing at the glass tube opening prevents unwanted AgCl-electrolyte reactions during temperature fluctuations, maintaining reference electrode stability and extending overall electrode service life.
