Bluelab pH Probe KCl Storage Solution 100ml

Bluelab pH Probe KCl Storage Solution 100ml

The proper way to store Bluelab pH probes when not in use — KCl (potassium chloride) storage solution keeps the probe hydrated and chemically balanced, dramatically extending its useful life. pH probes are sensitive glass instruments that age through normal use; storing dry accelerates that ageing and ruins probes prematurely.

Why growers need KCl storage solution:

• Extends pH probe lifespan significantly — properly-stored probes last years longer than dry-stored ones
• Keeps probe hydrated — prevents the glass surface from drying out and fracturing at microscopic level
• Chemically stable storage medium — doesn't degrade the probe like storing in pure water would
• Essential maintenance for Bluelab pens — genuine Bluelab solution, guaranteed compatibility
• 100ml bottle — enough for multiple probe-storage refills
• Protects your Bluelab investment — a £60 pH pen with a £9 storage solution lasts far longer

Who it's not for:

Specifically for pH probe storage — not a calibration solution. For calibration, use pH 4 and pH 7 buffer solutions. If your pH pen has lasted less than a year despite regular use, you probably haven't been storing it in KCl; start now and preserve what you have. Refill the probe cap regularly; don't let it run dry.
