Multi-Channel Protein Purification System with A260/A280 Detection (CAT#: STEM-BC-0005-ZJF)

The Multi-Channel Protein Purification System is designed for automated protein detection, concentration estimation, and sample collection during purification workflows. The system uses absorbance measurement principles based on the characteristic absorption peaks of proteins at 280 nm and nucleic acids at 260 nm. By measuring the absorbance of protein solutions, it calculates protein concentration and automatically transfers qualified samples into corresponding collection tubes once the preset threshold is reached. The system also calculates the A260/A280 ratio to evaluate sample purity and identify potential contamination. Impure fractions can be discarded automatically, improving purification efficiency and sample quality control.
