Spectra/Chrom® Fraction Collector, CF-2, Spectrum® Chromatography

About this item

The Spectra/Chrom® CF-2 Fraction Collector can be used with low-pressure liquid chromatography, RBLC, HPLC, and other procedures involving the measured collection of liquid fractions.

Collection of fractions based on time, number of drops, or number of volumes
Automatic peak detection based on slope or threshold
Programmed delay time to allow for synchronization with the detector
Up to ten time windows may be programmed to control collection
Direct control of either a 2-way security valve or a 3-way diverter valve (sold seperately)
On-line context-sensitive help messages guide the user through programming
Internal heaters allow operation in cold-rooms down to 0º C

Fractions can be collected on the basis of time (6 sec. to 999 min. and 59 sec.); counted drops (1 to 9999 drops); or other counted events (1 to 9999), e.g., the volume pulses output by a Spectra/Chrom pump. The maximum tube capacity is 174 tubes (12 or 13 mm Ø), 116 tubes (10 to 16 or 18 mm Ø), or 42 vials (28 mm Ø).

Certifications: CE marked.
