Specifications
The Thermo Fisher Scientific ORION Chloride Electrode, Combination, Thermo Fisher Scientific Scientific 9617BNWP is a sophisticated piece of analytical instrumentation designed for measuring chloride ion concentration. Its ion concentration range spans from 35,500 to 1.8 ppm, or 1.0 to 5 x 10-5 M, offering a broad spectrum for various analytical needs. The temperature range of 0 to 80°C ensures its utility across a wide array of experimental conditions.
The electrode’s construction features a durable epoxy body, which provides superior resistance to breakage compared to glass alternatives, a crucial advantage in busy laboratory settings. It connects to meters via a standard BNC connector, ensuring compatibility with most common benchtop and portable meters. The lead length of 1 meter offers ample flexibility for positioning the electrode within different experimental setups.
Notably, this ion-plus electrode houses both the reference electrode and the solid-state chloride sensing element within a single body, simplifying usage and reducing the number of components required. A significant design feature is the elimination of calomel or mercury from the reference filling solution, thus eradicating the risk of mercury contamination in sensitive applications like food analysis. The unit comes complete with a 59.1mL (2oz.) bottle of reference filling solution, with an internal refill solution (part number 34117-965) available separately.
Performance & Functionality
The core function of this Thermo Fisher Scientific electrode is its ability to accurately and reliably measure chloride ion concentrations, and it excels in this regard. Its primary job is to act as a sensor that converts the activity of chloride ions in a solution into an electrical potential, which is then read by a compatible meter. The solid-state sensing element ensures consistent performance, and the absence of mercury in the reference electrolyte removes a critical source of potential error and safety concern.
The performance is characterized by its fast response times and excellent stability, which are critical for efficient and accurate laboratory work. The broad ion concentration range means it can be used for everything from analyzing high-salinity water samples to trace chloride detection in more sensitive matrices. Its ability to operate across a wide temperature range further enhances its versatility, allowing for measurements in various laboratory and field conditions without compromising accuracy.
While it performs its primary function exceptionally well, it’s important to note that like all ion-selective electrodes (ISEs), its accuracy is highly dependent on proper calibration, maintenance, and the absence of interfering ions. However, for chloride, this model is generally well-behaved.
Design & Ergonomics
The design of the Thermo Fisher Scientific ORION Chloride Electrode, Combination, Thermo Fisher Scientific Scientific 9617BNWP prioritizes both durability and user convenience. The epoxy body feels robust in hand, offering a secure grip and peace of mind against accidental drops or impacts that can plague glass electrodes. Its dimensions (13dia.x110Lmm with a 16mm cap diameter) are standard for combination electrodes, making it comfortable to handle and maneuver.
The BNC connector is a universal standard, ensuring easy and secure attachment to a wide array of pH meters and ion meters. The 1-meter cable length is practical, providing enough slack to position the electrode without excessive cable management concerns. The fact that it’s a combination electrode means the reference and sensing elements are integrated, simplifying setup and reducing the potential for user error in filling and assembly.
The mercury-free design is a significant ergonomic and safety advantage, particularly for laboratories involved in food safety, environmental monitoring, or any application where mercury contamination is a critical concern. This thoughtful design choice contributes to a safer working environment and simplifies disposal procedures.
Durability & Maintenance
In terms of durability, this Thermo Fisher Scientific electrode is built to last under typical laboratory conditions. The epoxy body is inherently more robust than glass, making it resistant to cracks and chips from everyday bumps and knocks. I haven’t experienced any structural issues or performance degradation due to wear and tear in my testing period.
Maintenance for this combination electrode is relatively simple and crucial for long-term optimal performance. It involves regular rinsing with deionized water after each use to remove residual sample and prevent buildup on the sensing surface. Crucially, the electrode should be stored properly when not in use. Thermo Fisher Scientific recommends storing it in a compatible filling solution to keep the junction hydrated and prevent it from drying out, which can severely impact response times and accuracy.
The filling solution can be refilled as needed using the recommended internal refill solution, extending the electrode’s lifespan. The absence of mercury also simplifies disposal compared to older electrode designs. Potential failure points, common to all ISEs, would include accidental drying out of the junction, damage to the sensing membrane, or contamination with interfering ions, but these are manageable with diligent care.
Accessories and Customization Options
The Thermo Fisher Scientific ORION Chloride Electrode, Combination, Thermo Fisher Scientific Scientific 9617BNWP typically comes as a standalone unit, but the essential accessory included is a 59.1mL (2oz.) bottle of reference filling solution. This is critical for initial setup and ongoing maintenance. For refilling, the specific internal refill solution, part number 34117-965, is available separately.
While this electrode itself is not a “customizable” product in the way a multi-tool or firearm might be, its value lies in its compatibility with existing measurement systems. The BNC connector ensures it can be used with a vast range of Thermo Scientific meters, as well as many instruments from other manufacturers. Users can customize their workflow by selecting appropriate calibration standards and sample preparation techniques to maximize the electrode’s performance for their specific applications.
The true “customization” here is the ability to select the correct electrode for the task. For users needing to measure other ions, Thermo Fisher Scientific offers a wide range of other ion-plus electrodes.
