LabSen 841 pH Electrode
Built with proprietary sensor technology and premium materials from Switzerland, LabSen 841 pH Electrode and MP500 Temperature probe, designed for measuring strong alkaline solutions.
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.
Swiss HA glass membrane
LabSen HA membrane is made for strong alkaline solutions (10-14 pH) and high salinity solutions, effectively minimizing alkaline errors caused by sodium ions. Compared with conventional electrodes, its service life testing these samples is 5 times longer.
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.
