LabSen 831
LabSen 831 pH Electrode and MP500 Temperature probe, designed for measuring solutions containing strong acid or hydrofluoric acid.
Specialized Electrolyte
Apera's proprietary blue gel inner solution does not flow at all, which means it will never generate air bubbles. The electrode can work well even when being held upside-down. It is not only more convenient to use, but also improves the measurement accuracy by eliminating heat convection in the inner glass membrane.
HF glass membrane
The equipped Swiss LabSen 831 Glass pH Electrode adopts a special HF glass membrane, which is resistant to HF corrosion and is capable of measuring solution containing HF acid for up to 1000 times. (measurement time<1 minute, and HF concentration should be less than 0.1mol/L or 0.2% wt%)
Silver-ion-trap reference system
The combination of a Long-life reference system and a silver ion trap. The silver ion trap will absorb all the exuded Ag+, ensuring that there's no Ag+ in the reference electrolyte, and avoiding junction clogs caused by samples containing sulfides, proteins or TRIS buffer solutions.
