pH Electrode Storage Solution (25 mL)

Reference HI70300S

HI70300S is a storage solution prepared with reagent grade chemicals that can be used to ensure optimum performance of your pH and ORP electrodes. It is necessary to store a pH electrode in a solution in order to keep the glass membrane of the pH electrode hydrated. Ideally a storage solution should be used; never store an electrode in distilled or deionized water. The Hanna Instruments storage solution is specifically formulated to minimize microbial growth and to prevent any diffusion/osmotic effects from storing a probe in a solution with the highly concentrated inner reference electrolyte. Storing your pH and/or ORP electrodes in a storage solution will also keep the junction clear. Maintaining the hydrated layer and clear junction will help to ensure a fast and reliable measurement. In the case of cleaning your pH electrode in one of our cleaning solutions, we recommend soaking the electrode in the HI70300S storage solution for at least one hour before taking measurements.

Maintenance contract — AxiTech provides planned preventive maintenance for pH Electrode Storage Solution (25 mL) from Hanna Instruments: scheduled visits, safety checks, periodic calibration and a documented service report, backed by a contractual response time.

Troubleshooting, repair and spare parts — our ph, conductivity & water analysis engineers diagnose and repair pH Electrode Storage Solution (25 mL) on site or in the workshop, fit genuine spare parts and recommission the equipment after performance verification.

Features

Special formulation to minimize microbial growth and osmotic/diffusion effects between the solution and inner reference electrolyte
Manufactured specifically for pH and ORP electrodes
Clearly marked expiration date and lot number

Supply and reordering

AxiTech supplies pH Electrode Storage Solution (25 mL) alongside the instruments it is used with, so a calibration or a service visit never stalls waiting on a consumable.

Ordering pH Electrode Storage Solution (25 mL)

Tell us the reference and the quantity and we come back with a price, a lead time and the batch documentation. Consumables ordered against a maintenance contract are scheduled with the visit, so they arrive with the engineer rather than after them.

Batch and expiry documentation supplied with every delivery
Quoted with a lead time, not just a price
Scheduled with your maintenance visit when you hold a contract
Standing orders for items you consume on a predictable cycle

The instrument it belongs to

The Hanna Instruments equipment pH Electrode Storage Solution (25 mL) is used with is what AxiTech maintains, calibrates and repairs. If you operate it, we can put it under a preventive maintenance contract and supply this item as part of the schedule.

Questions we are asked

Frequently asked questions about Hanna Instruments pH Electrode Storage Solution (25 mL)

Yes. AxiTech supplies pH Electrode Storage Solution (25 mL) to hospitals, clinics and laboratories, either as a one-off order or on a standing schedule. Send us the reference and the quantity and we come back with a price and a lead time.

It depends on whether the item is held regionally or ordered from the manufacturer, so we confirm a date with the quotation rather than after the order. Items covered by a maintenance contract are planned ahead of the visit so they are on site when the engineer is.

Yes. Consumables and wear parts can be written into the contract and delivered on the maintenance schedule, which removes the reorder cycle and the risk of a visit stalling because something was out of stock.

Follow the manufacturer’s storage temperature and observe the expiry date printed on the batch: an out-of-specification standard or reagent will quietly bias every result measured against it. We supply batch documentation with each delivery so the traceability is there for an audit.

Yes. Maintenance, calibration and repair of the instrument is AxiTech’s core business, and this item is one of the things we supply as part of that. Tell us the model you operate and we will propose a maintenance schedule around it.
