Model BK-CW2000B
Introduction:
Micro-Volume UV/VIS spectrophotometer is a high-precision analytical instrument requiring no warm-up and offering simple operation. It rapidly and accurately measures nucleic acids, proteins, and cell solutions using only 0.5~2µL samples. Its cuvette mode also supports concentration measurement of solutions such as bacterial cultures. Equipped with fluorescence detection, the device is compatible with fluorescence quantitative assay kits. Based on the specific binding of fluorescent dyes to target substances, it enables highly precise quantification of DNA, RNA, and proteins, with dsDNA detection sensitivity as low as 0.5pg/µL—ideal for trace sample analysis.
