A new clinical version of the manufacturer’s existing flame photometer adds sodium linearization for simple calibration, providing a low-cost instrument with high precision, ergonomic design and ease of maintenance. The controls are located on the front of the instrument, making it easy to use. A large, unobstructed sample work area features a spill containment tray that is easy to remove and clean. LEDs on the front panel indicate the filter selected – sodium, potassium, lithium, calcium or barium – and the flame status. The detector response is automatically ‘linearized’ over the clinical measurement range when the sodium filter is selected.
