Bluelab Solution Sachet 30 Box – PH418B

Product Description

The Bluelab Solution Sachet 30 Box (code PH418B) is a pack of single-use calibration and storage solution sachetsdesigned for pH and EC probes, pens, and meters. Instead of large bottles, this box contains 30 individual sachets of ready-to-use liquid, each sized for one calibration or storage use. These sachets are ideal for on-the-go calibration, travel, workshops, labs, field work, or anytime you want a portable and convenient way to maintain your measurement tools.

This specific PH418B variant contains pH 4.0 calibration solution sachets, which are used to calibrate pH probes at the lower (acidic) calibration point during two-point calibration. Two-point calibration (for example at pH 7.0 and pH 4.0) ensures your probe reads accurately throughout the measuring range.

An easy way to keep your pH and EC probes or pens accurate and working at their best

Features:

• Easy-to-open single-use sachets of calibration and storage solutions
• Quick tear-open sachets are suitably sized for on-the-go calibration and probe storage

Key Features & Benefits

• Portable & Single-Use: Each sachet contains a single mL amount of solution — perfect for field use, workshops, or calibration routines without needing large bottles.

• Accurate Calibration: Provides a precise and stable known pH value (4.0) for calibrating the lower end of your pH meter’s range.

• Convenient & Clean: Tear-open sachets reduce contamination risk compared to repeatedly dipping probes into bottles.

• Easy to Carry: Ideal for growers, technicians, labs, or anyone needing quick calibration while away from a stationary setup.

Typical Use

1. Tear open one sachet and pour the contents into a small clean container.

2. Rinse your pH probe in clean water and shake off excess.

3. Immerse the probe tip in the solution and allow it to stabilize.

4. Follow your meter’s calibration procedure to set the pH 4.0 point.

5. Discard the used solution and rinse the probe before storing or taking measurements.
