Fraction Collector, CF-2, Spectra/Chrom

The CF-2 includes a powerful peak detector that lets you separate the low-level "in-between" material from the peaks. Simply connect the chart recorder output from your detector to the input of the CF-2 and you can put different amounts in the peak and non-peak tubes as well as keep your peaks more concentrated by separating them from the non-peak material. Add a 3-way diverter valve and you can skip collecting the in-between material altogether!

While most chromatography needs can be met with the standard CF-2, options are available that can expand its versatility:

Collect up to 29 fractions from each of 4 separate columns simultaneously with the 4-column adapter.

Short on bench space? use the mast package to move other instruments and accessories up, out of the way.

Worried about dust or other contamination when doing long collections? Then use the dust cover to reduce the chances of this happening.
