HI7004L | Hanna pH Buffer Solution 4.01 - 500ml

Secure the accuracy of your acidic measurements with the Hanna HI7004L pH 4.01 Calibration Solution, the industry-standard buffer for analyzing low-pH samples in Pakistan's agriculture, food, and water treatment sectors. Proper calibration requires "bracketing" your measurement range; if you are testing acidic substances (below pH 7), such as fruit juices, wine, or soil, calibrating with pH 4.01 is mandatory to establish the correct electrode slope.

The HI7004L comes in a 500 mL bottle and is tinted red, allowing for instant visual identification to prevent cross-contamination with other buffers. Manufactured to ISO 3696/BS3978 standards and traceable to NIST, this solution ensures your data is defensible and precise. The label includes a temperature correlation chart, enabling accurate calibration at any ambient temperature.

Frequently Asked Questions:

• Q: Why is the solution red?

  • A: Hanna color-codes their buffers for safety and convenience. Red is for pH 4.01, Green is for pH 7.01, and Violet is for pH 10.01. This prevents users from accidentally calibrating with the wrong liquid, which would skew all subsequent readings.

• Q: When should I use pH 4.01?

  • A: You should use this buffer as your second calibration point (after pH 7.01) whenever your expected sample is acidic (pH < 7). This applies to most food products, many industrial effluents, and soil acidity testing.

• Q: Can I reuse the buffer after pouring it into a beaker?

  • A: No. Once the solution is exposed to air and your electrode, it becomes contaminated. Always discard the used portion and pour fresh buffer for every calibration to ensure accuracy.
