Real-World Testing: Putting WTW Buffer 50ml pH 4.01 Traceable 108706 to the Test

First Use Experience

My initial test involved calibrating a handheld pH meter I use for assessing water sources in remote locations. I performed the calibration according to the meter’s instructions, using the WTW Buffer 50ml pH 4.01 Traceable 108706 as my low-end calibration point. The meter calibrated perfectly, displaying the expected 4.01 pH value.

I tested the buffer in varying weather conditions, including a humid, rainy day in a swamp and a dry, windy day by a mountain stream. The buffer performed consistently, providing stable and accurate calibration points regardless of the environmental conditions. There was no observable difference in calibration behavior across temperatures and conditions.

Using the WTW Buffer 50ml pH 4.01 Traceable 108706 was straightforward. The instructions are clear, and the small bottle size made it easy to handle and dispense the solution. It was just a couple of drops to get my meter accurate.

After the first use, I noted the calibration held true even after the meter had been stored and transported. I was pleased by how resistant the meter was to changes in calibration when started back up in the field. This indicates that the buffer allowed for a quality calibration.

Extended Use & Reliability

After several months of using the WTW Buffer 50ml pH 4.01 Traceable 108706 across numerous field tests, the solution has proven incredibly reliable. The calibration remains consistent, ensuring accurate pH readings for every water sample I analyze. I used about 1/4 of the bottle with over 10 calibrations.

Despite being subjected to the rigors of outdoor use, including temperature fluctuations and jostling in my gear bag, the bottle shows no signs of leakage or degradation. The buffer solution itself remains clear and uncontaminated. The plastic seems resilient to changes in temperature.

Maintaining the buffer is simple. After each calibration, I ensure the bottle cap is tightly sealed and store it in a cool, dry place away from direct sunlight. I take care to not contaminate the inside of the cap.

Compared to my previous experiences with less traceable or less reputable pH buffers, the WTW Buffer 50ml pH 4.01 Traceable 108706 significantly outperforms them. I previously needed to calibrate my meter with much more frequency, but I feel safe with the buffer in the field. The accuracy and consistency are unmatched, providing me with the confidence I need to make informed decisions about water safety.

Breaking Down the Features of WTW Buffer 50ml pH 4.01 Traceable 108706

Specifications

• Manufacturer: WTW. This is a well-regarded manufacturer of laboratory equipment, ensuring a degree of quality and reliability.
• Volume: 50 ml. The small volume is practical for field use, minimizing weight and space.
• pH Value: 4.01. This is a standard pH value, commonly used for calibrating pH meters.
• Traceability: Traceable to NIST. This is a critical feature, as it ensures the buffer’s accuracy and consistency are verifiable against a recognized standard.
• Reference Temperature: 25 °C. The buffer is most accurate at this temperature, but pH meters typically compensate for temperature variations during calibration.

These specifications are important because they directly impact the accuracy and reliability of pH measurements. The NIST traceability provides confidence in the buffer’s pH value, while the volume and reference temperature contribute to ease of use and practical application. Ultimately, you can count on the buffer to be accurate if the meter is accurate!
