APERA INSTRUMENTS LabSen 241-6 Semi-Micro pH Electrode
LabSen electrochemical sensors are premium pH electrodes with manufacturing technology and key components imported from Switzerland. been 241-6 semi-micro pH electrode is suitable for micro samples (≥0.2ml) in small containers, such as tubes and vials. This probe has the following features:
- Impact-resist membrane, there is no danger of electrode breakage during normal use.
- Blue gel inner solution does not flow and will not cause a bubble.
- Long life reference system, has better stability and service life.

Usage and Maintenance
-
Connect BNC plug to the input on the pH meter.
-
When measuring, please unscrew the bottle cap, pull out the electrode and rinse it with deionized water. After using, please put the electrode back into the bottle and screw tight the cap.
Before pulling out or putting back the electrode, fully loosen the blue cap on the storage sleeve so that the electrode can move in and out smoothly. -
Prior to measurement, remove the rubber plug to maintain the pressure of the reference solution, and keep a consistent flow rate of reference solution and stable potentials of the junction.
-
After a period of usage, the reference solution will run low. Whenever the level falls to 1/2 height of the electrode, add 3M KCL solution to the refilling hole by using a syringe or pipette.
-
The connector of the electrode should keep clean and dry. If being contaminated, please clean it with medical cotton and absolute alcohol and blow dry to prevent a short circuit of the electrode and slow reaction of the electrode.
-
The electrode’s measuring tip should be soaked in the soaking bottle containing a certain amount of storage solution to keep the membrane hydrated and the junction unblocked. Clean the bottle and replace the storage solution if the storage solution gets turbid and mildewed. The electrode should never be sunk in pure water or buffer solution for long.
-
After 1-year of use, we recommend replacing the electrode to ensure the best accuracy.
