It is supplied with 50mL of internal filling solution (part number 34111-830), which is essential for maintaining its operational integrity.
Performance & Functionality
The primary job of this electrode is to accurately measure fluoride ion concentrations, and it performs this task exceptionally well. Its sensitivity allows for precise clinical and analytical applications, a claim I can attest to from my own lab work. The solid-state reference design means less maintenance and greater stability, particularly crucial for long-term monitoring or complex sample matrices.
A significant strength is its versatility; it is described as rugged enough for field use, a testament to its robust construction and stable performance. While I primarily use it in a lab setting, the implied durability is reassuring. Its ability to handle small sample volumes is also a major plus, reducing waste and allowing analysis of precious samples.
The main limitation, common to all ion-selective electrodes, is its susceptibility to interference from other ions under certain conditions. However, for standard fluoride measurements in water and common biological samples, its performance is largely uncompromised. It consistently meets and often exceeds expectations for reliability in routine analytical tasks.
Design & Ergonomics
The epoxy body construction provides a good balance between durability and handling comfort. It feels solid and well-made, not cheap or flimsy. The overall design is functional and straightforward, focusing on efficient operation rather than aesthetics.
Ergonomically, the electrode is easy to grip and manipulate during sample immersion and rinsing. The 1-meter cable offers good reach, preventing awkward positioning or strain.
