Fraction Collector

A Fraction Collector is used to automatically collect liquid samples (fractions) coming from a chromatography column. It enables researchers to separate complex mixtures into individual components by collecting them in a time-based, drop-based, or signal-based sequence. It is essential in biochemical, pharmaceutical, and analytical labs for reproducible sample collection and purification.

Fraction Collector is an important tool in various chromatography applications as during a chromatography run, the output from the column is directed to a fraction collector. The collector receives signals (such as time intervals, drop counts, or peak detection data) and moves the test tube tray or collection arm to deposit each fraction in a designated tube. This allows precise collection of separated compounds without manual intervention.

Yes, most of the Labtron’s Fraction Collectors can be triggered externally via signals from detectors (UV, RI, conductivity) or chromatography software. This allows automated and accurate peak-based collection, ideal for separating closely eluting compounds or monitoring real-time sample outputs.

Solvent compatibility is critical, especially in chromatographic separations involving organic solvents, acids, or buffer solutions. A Fraction Collector must be constructed from chemical-resistant materials (e.g., PTFE, ABS, stainless steel) to ensure long-term durability and prevent damage or contamination.
