What is Flairform pH Electrode Storage Solution used for?
It's used to keep pH probe tips properly hydrated when not in use, which helps maintain accuracy, faster readings, and longer probe lifespan. Dry storage is one of the most common causes of poor calibration, slow response, and early probe failure.
Can I store my pH probe in tap water or distilled water instead?
No. Tap water can contaminate the probe over time, and distilled or RO water can actually damage it by leaching ions. Only use proper KCl-based storage solution like Flairform pH Electrode Storage Solution to protect the glass bulb and reference junction.
Is Flairform pH Electrode Storage Solution compatible with all pH probes?
Yes, it's suitable for most standard pH probes, including those from Bluelab, Apera, Hanna, and Aqua Master. If you’re using a specialty probe, follow the manufacturer’s care instructions. It’s not for EC or temperature probes.
How much storage solution should I use, and how do I store the probe?
Fill the storage cap with enough solution to fully cover the glass bulb, then cap the probe and store it upright. A weekly top-up is ideal, especially in warm grow rooms where evaporation is faster. Avoid long-term open cup storage unless sealed.
What should I do if my pH probe has dried out?
Soak the tip in Flairform pH Electrode Storage Solution for 24–48 hours to try rehydrating it. Then calibrate and check for recovery. If the probe still drifts, won’t calibrate, or reads slowly, it may be too far gone and need replacing.
Does storing in Flairform pH Electrode Storage Solution prevent pH drift?
It helps significantly. Keeping the probe hydrated reduces drift and speeds up stabilisation. However, for accurate readings you still need to calibrate regularly and clean the probe if there’s nutrient or salt buildup.
Should I rinse or clean my pH probe before and after storage?
Yes. Rinse with clean water before putting it into storage, and again before measuring. If the probe has visible residue or has been used in nutrients, clean it first with a proper electrode cleaner before storage.
Why does the solution keep disappearing from my probe cap?
Evaporation—especially in warm or dry environments. Check the cap fit, top it up regularly, and keep the bottle sealed tight between uses. White crystals on the probe are normal and will rinse off.
Can I reuse Flairform pH Electrode Storage Solution or pour it back into the bottle?
No. Once it’s been exposed to air or used in a cap, it can be contaminated. Always use fresh solution and discard the old. Store the bottle upright, sealed, and out of direct light to keep it stable and clean.
Do I still need to calibrate if I store my probe in this solution?
Yes. Storage solution maintains probe health, but doesn’t replace calibration. Use proper pH buffers (like pH 4.0 and 7.0) and calibrate monthly or more often if you rely on precise readings.
Is Flairform pH Electrode Storage Solution safe to handle?
It’s generally safe for normal use. Avoid eye contact, don’t ingest it, and wash your hands if you spill it. As with any lab-grade solution, keep it away from kids and pets.
What size does Flairform pH Electrode Storage Solution come in?
It’s commonly available in a 250 mL bottle, which lasts a long time when used for topping up storage caps. Perfect for home growers or commercial setups maintaining multiple probes.
What’s the best routine for using Flairform pH Electrode Storage Solution?
Rinse the probe after use → top up the cap so the bulb stays fully submerged → recap immediately → refresh the solution weekly → clean the probe as needed → calibrate regularly for best performance.
