Flairform pH 7 (250ml + 1L)

What is Flairform pH 7 and why do I need it?

Flairform pH 7 is a calibration buffer solution with a stable pH of 7.0. It’s essential for keeping your pH meter accurate—especially in hydro or coco, where pH drift can cause nutrient issues. It acts as a reliable reference point during calibration.

Can I calibrate with just Flairform pH 7?

Some meters allow one-point calibration at 7.0, but two-point calibration (pH 7 and pH 4) is more accurate. Start with Flairform pH 7, then calibrate with the second buffer as directed by your meter’s instructions.

What pH meters is Flairform pH 7 compatible with?

Flairform pH 7 works with nearly all digital pH pens, meters, monitors, and controllers—including Bluelab, Hanna, Aqua Master, and others. It’s suitable for hydro, soil probes, aquaponics, and any meter that uses pH 7.0 for calibration.

How do I use Flairform pH 7 properly?

Rinse your probe, pour a small amount of Flairform pH 7 into a clean cup, insert the probe, gently stir, and wait until the reading stabilizes near 7.0. Never dip into the bottle, and discard used solution after each use.

Why won’t my meter calibrate in Flairform pH 7?

Common causes include old buffer, dirty or dry probes, low batteries, or worn sensors. If your meter reads far from 7.0 in fresh solution, it’s time to recalibrate or clean/replace the probe.

How often should I calibrate with Flairform pH 7?

Calibrate monthly at a minimum. If you're checking pH daily, calibrate more often—especially after cleaning the probe, changing batteries, or noticing unusual readings.

Does temperature affect Flairform pH 7 readings?

Yes. Buffers can read slightly off if the temperature varies widely. Let the buffer reach room temperature, and use meters with ATC (auto temperature compensation) for better accuracy.

How should I store Flairform pH 7?

Keep the bottle tightly sealed, away from heat and sunlight. Never return used solution to the bottle, and avoid dipping dirty probes into it. Evaporation or contamination can ruin accuracy.

Is Flairform pH 7 safe to handle?

Yes, but it’s not for ingestion or eye contact. Wash your hands after use, keep it away from children or pets, and don’t use it as probe storage solution—it’s only for calibration.

What sizes is Flairform pH 7 available in?

It’s commonly available in 250 mL and 1 L bottles. The smaller size suits hobby growers, while the larger bottle is ideal for frequent calibration or commercial setups.

Can I reuse Flairform pH 7 or pour it back into the bottle?

No. Reusing or returning used buffer contaminates it and leads to inaccurate calibration. Always pour out a fresh small amount, use it once, and discard it afterward.
