: Avantor
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 0 °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).
