PerpHecT ROSS Combined pH Microelectrode PerpHecT ROSS

Micro electrodes are designed to measure small volumes down to 0.5 μL. A wide variety of electrodes are available depending on measurement needs.

ROSS 8220BNWP micro electrodes offer the best accuracy and response time of all micro electrodes.

They can be used in biological samples.

The 8220BNWP is more durable than silver chloride electrodes.

To ensure fast response and gravity bonding for liquids, the sensing element and reference gasket must not dry out.

Short-term storage (up to one week): Immerse the electrode in ROSS pH electrode storage solution, Orion 810001 or use pH electrode storage solution, Orion 910001. To minimize the risk of breakage, the 8220BNWP should be connected to an electrode holder and suspended in a beaker containing pH electrode storage solution. The electrode should not touch the walls or base of the beaker.

Long-term storage (more than one week): The reference chamber should be filled and the filling hole adequately covered. Use the protective cap or sleeve with a few drops of storage solution to cover the sensing element and reference junction. Before reusing the electrode, prepare it as if it were a new one.
