Essentials LAB pH Buffer Fluid

Essentials LAB pH Buffer Fluid

Essentials LAB pH Buffer Fluids provide highly accurate calibration solutions for maintaining precise performance in any pH meter. Available in pH 4 and pH 7, each buffer ensures your meter reads correctly, allowing you to keep your nutrient solution within the ideal range for healthy plant growth. Choose from 1L or 250ml bottles depending on calibration frequency and grow room needs.

Regular calibration is essential because pH probes naturally degrade over time. Using Essentials LAB Buffer Fluids helps restore accurate readings, prevents drift, and improves the reliability of every pH measurement you take. For best accuracy, most growers use pH 7 for single-point calibration or pH 4 and pH 7 together for full two-point calibration.

Each solution is manufactured to strict laboratory standards, delivering stable, reliable results whether you calibrate weekly or before every mix. To avoid contamination, always pour a small amount into a secondary container and discard after use.

Essentials LAB Buffer Fluids are a must-have for any grower who relies on consistent, accurate pH control for nutrient uptake, plant health, and overall performance.

Key Benefits:

• Industry standard – compatible with nearly all pH readers

• Helps keep your pH meter reading consistently and correctly

• Supports both single-point and two-point calibration

• Manufactured to laboratory standards for stable, consistent results

Instructions for Use:

• Keep the buffer fluid and pH meter at similar temperatures before calibrating

• Shake the bottle gently before pouring

• Pour a small amount into a clean container—never insert the probe directly into the bottle

• Calibrate your pH meter according to the manufacturer’s instructions

• Discard used solution after each calibration session

• For maximum accuracy, perform two-point calibration using both pH 4 and pH 7 fluids

• Store upright, tightly sealed, and out of direct sunlight between 5°C and 25°C
