Sherwood 410 Single-Channel Flame Photometer for Sodium, Potassium, and Lithium Analysis

The Sherwood 410 Flame Photometer is a robust, low temperature, single-channel analytical instrument designed for precise determination of sodium (Na), potassium (K), and lithium (Li) concentrations in clinical and biological samples. Widely used in molecular diagnostics, clinical chemistry, and biotechnology applications such as bioprocessing and synthetic biology, this flame photometer offers reliable and sensitive elemental analysis critical for biochemical assays.

Key technical features include:

• Pre-fitted Na, K, and Li optical filters and a multi-element calibrator in mmol/L to ensure accurate quantification.
• Digital interface enabling connection to computers or printers for data logging with sequence numbers, sample designation, and timestamp.
• A built-in sodium linearization function allowing direct calibration over clinically relevant sodium ranges (100–200 mmol/L), enhancing measurement precision in serum samples.
• Rapid analysis speed with a time to stability of approximately 15 seconds.
• Measurement ranges of 0–1999 mmol/L for Na, K, and Li, suitable for both clinical diagnostics and biotechnology research workflows.
• Reproducibility with less than 2% variation at 10 ppm potassium from 20 aliquots, reflecting high analytical accuracy.
• An aspiration rate adjustable between 3–6 mL/min optimizes sample throughput and flame stability.
• Analog voltage data output (0.20 Volts FSD) facilitates integration with laboratory data systems.

This flame photometer is essential in clinical diagnostics, biomedical engineering, and biopharmaceutical production pipelines, supporting workflows in molecular cloning, electrolyte analysis, and cell physiology studies. Its precision and ease of use make it a popular instrument among researchers focused on fluorescence analysis, live-cell imaging correlations, and element-specific biochemical quantification.
