723型可见分光光度计是采用单片微机控制的中级型智能化仪器。仪器能在近紫外、可见光谱区对样品物质作定性和定量分析。仪器波长精度高、读数稳定,具有自动调整满度、调整零点、比色皿四孔校正、自动扫描绘图和数据打印等功能。可广泛用于医疗临床、无机分析、酶分析、药品检验、环境保护等领域。仪器主要技术指标如下:
The Model 723 Visible Spectrophotometer is a mid-range, intelligent instrument that uses a single microcomputer control. The instrument is capable of qualitatively and quantitatively analyzing sample substances in the near-UV and visible spectral regions. Instrument wavelength accuracy, stable readings, with automatic adjustment fullness, zero adjustment, cuvette four-hole calibration, automatic scanning graphics and data printing capabilities. Can be widely used in medical clinical, inorganic analysis, enzyme analysis, pharmaceutical testing, environmental protection and other fields. The main technical indicators are as follows:
