## Overview

Apera Instruments 3M KCL Storage Soaking Solution (8 oz) is a reagent-grade, double-sealed electrolyte solution designed to condition and extend the life of pH and ORP electrodes. Its precise 3M KCl concentration restores sensor sensitivity and accuracy, while the clear expiration date ensures optimal freshness. Ideal for professionals and home users seeking reliable, long-lasting probe performance.

## Description

Apera Instruments 3M KCL storage solution is made with high-purity chemicals, designed for conditioning and extending the service life of pH or ORP electrode. pH/ORP electrodes that are stored dry over time may lose the sensitivity and accuracy temporarily. It can be restored by soaking them in the storage solution. Keeping pH/ORP electrodes stored in the storage solution when not in use is a recommended practice. Double-sealed packaging. Expiration date specified on the bottle. Volume: 8oz.

Review: Good quality product. - Works well. Does what it is supposed to do.
Review: Cost effective quantity for home users - I have a smart pH sensor for my pool that needs to be stored in 3 M KCl solution during the winter months when the pool is closed. It only needs a tiny amount of fluid, so this container is a little bit of overkill, but compared to some other products this one is pretty inexpensive, making it the best choice. It's the proper concentration that my sensor manufacturer specifies, and the bottle is easy to handle and pour. It arrived without any leakage and is just what I needed!

## Questions & Answers

**Q: How much storage solution do you use and do you change it each time you use the device?  New to this.  Thank you.**
A: I do not change it every time I use the device. I rinse my probe of in distilled and shake/pat dry. The kit come with a storage cap. It has a fill  line.  I was told on the phone by apera that if storing in the case fill to about half way to the fill line and make sure probe is wet.  It's only a few Ml in the cap. I normally top it off when needed but the bottle should last you a very long time. I use it to refill the small bottle in the kit.  It's not completely air tight so you may find some solution crust around the top of the cap from time to time. just clean it and you should be good.  I am using my meter 3-5 times a week now and have only used about 1" of solution out of the bottle in two months.

**Q: Is this solution only used for long term storage, or short term as well? Is there a need to recalibrate after storing in this?**
A: You have to calibrate the meter weekly; if storing longer, calibrate it before use. the solution is good until the next time you use the meter.

**Q: This states to use storage solution when not in use is a recommended practice, what is the "recommended practice" as it does not state on the PH20?**
A: It is recommended in the PH20 instructions to use the Apera product (Kaliumchlorid) to store the PH20.  That is, fill the container (probe protector)  to the line with the Kaliumchlorid liquid, and insert the probe into the protector.  I store the AP20 in its case and on its side (probe pointing down) to insure the probe is in the liquid.  This also prevents liquid from leaking out.

**Q: Is the solution placed in the cap of the PH20 meter?**
A: We now store the cap with water droplets to maintain a modest humidity in the cap. In this way, the probe is ready for its first customer, and they can choose whether to store in 3m KCl or use an alternative method.

### ⭐⭐⭐⭐⭐ Good quality product.
*by R***N on November 22, 2025*

Works well. Does what it is supposed to do.

### ⭐⭐⭐⭐⭐ Cost effective quantity for home users

### ⭐⭐⭐⭐⭐ Apera goes with apera
*by A***0 on May 24, 2025*

Excellent product, does what it's supposed to and keeps my apera ph20 ready to go for daily use. My only gripe would be that a storage solution should also come with the ph pens. Other than that, this product does what it's supposed to and apera knows what they are doing! With this solution I've only had to calibrate my ph20 2 times in the 5 months I've had it.
