photometer

This modern Flame Photometer makes sodium and potassium determinations faster than ever before! Reads directly in milliequivalents without curves or tables. The answer you get is the answer you want. A unique double control eliminates preliminary fussing. One lever selects the proper potentiometers and filters for either sodium or potassium readings. A pilot light and preset adjustments give instanta­ neous and efficient flame operation. To provide long life and trouble-free perform­ ance, this Photometer has a stainless steel atomizer separate from the burner. A nebulizing chamber shoots only finely atomized sample to the flame. This reduces internal moisture condensation and clogging deposits, and maintains the flame background noise at a low and steady level. Natural gas or propane, a source of compressed air, and household current make the Direct-Reading Flame Photometer instantly ready to operate.

The Beckman DirectReading Flame Photom­ eter is ideally suited for sodium and potassium studies in: human serum, blood, urine, food prod­ ucts, plant tissues, ferti­ lizers, soils, paper pulp, water, cement.
