Let’s Dive into Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN
The Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN promises precision pH measurement in the smallest of sample volumes, a crucial need for researchers and technicians working with limited materials. Thermo Fisher Scientific aims to deliver a reliable and accurate tool for tasks where traditional pH electrodes simply won’t fit. This micro pH electrode is designed for use with Thermo Fisher Scientific pH meters, offering a complete solution for demanding laboratory applications.
My work in environmental toxicology often involves analyzing pH levels in minute biological samples, making accurate micro-scale measurement essential. Traditional pH electrodes were bulky and required large sample volumes, which were often unavailable. The promise of the Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN to measure pH with only 0.5µL of sample intrigued me.
Upon unboxing, I was struck by the electrode’s slender profile. The glass body felt sturdy yet delicate, and the tip appeared meticulously crafted. The included accessories – the reference filling solution, adapter, and filling pipet – suggested a comprehensive package.
Compared to standard sized pH electrodes and even other micro-electrodes I’ve used, the ORION Micro pH Electrode stands out for its extremely small tip diameter (1.3mm) which is critical for accessing narrow containers or tiny samples. Other micro-electrodes I’ve used required at least 50µL of sample, a significant difference. The compact design and minimal sample requirement were the primary reasons I chose this Thermo Fisher Scientific product.
I was cautiously optimistic. The Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN seemed well-engineered, but its performance in real-world scenarios would determine its true value.
Real-World Testing: Putting Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN to the Test
First Use Experience
I first tested the Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN in my lab, analyzing the pH of cell lysates contained in small PCR tubes. The electrode’s slim design allowed me to easily insert it into the tubes without contaminating the samples. The readings stabilized quickly, providing a result within seconds.
The testing environment included both room temperature and temperature-controlled conditions (4°C and 37°C). The electrode performed consistently across the tested temperatures within its specified range of –5 to 100°C. I did find that the electrode needed a few extra seconds to stabilize when moving between different temperatures, requiring about 15 seconds for temperature equilibration.
The electrode was surprisingly easy to use, requiring only a quick calibration with standard pH buffers. The included adapter fit seamlessly with my existing electrode holder. A minor drawback was the need for careful filling of the reference solution to avoid air bubbles, though this is typical of combination electrodes.
My initial concern about fragile design proved unwarranted as the electrode tip was robust. I was relieved as I feared accidental breakage during the process of measuring small samples.
Extended Use & Reliability
After several months of consistent use, the Thermo Fisher Scientific ORION Micro pH Electrode, Combination, Thermo Fisher Scientific Scientific 9810BN continues to deliver reliable pH measurements. The glass body still looks as good as new, though it’s worth noting that I am extremely careful when handling and storing it. Regular rinsing with deionized water is essential.
No significant wear and tear is visible, although I make sure to store the electrode properly in its storage solution when not in use. Proper storage is crucial for maintaining accuracy and prolonging the electrode’s lifespan. I clean the electrode weekly with a mild detergent solution and recalibrate it before each series of measurements.
In comparison to other pH electrodes I’ve used, the ORION Micro pH Electrode is significantly better for low-volume applications. Its accuracy and speed are comparable to standard electrodes when measuring larger volumes, but it truly excels when sample size is a limitation.
