Fraction Collector
Model CF-1


The CF-1 Fraction Collector is a durable, general purpose, fraction collector. It can collect up to 174 fractions in 12 to 13 mm diameter tubes. The fraction collector is sold complete with a set of racks for holding 12 to 13 mm diameter tubes, a drop counter and former, and tubing fittings for 1/16 and 1/8 inch OD tubing and 1/16 inch ID tubing.
A variety of options are available for the CF-1 Fraction Collector which expand its versatility. These options include racks for other tube sizes, security and diverter valves, and cables to permit automated operation.
The CF-1 Fraction Collector can be operated as a simple fraction collector, where each fraction is the same size and the fraction size is set in terms of time, drops, or external events (like counts from a pump). A simple command entered from the membrane keypad enables the internal peak detector. This allows you to collect only those peaks of interest from the chromatogram and to ignore the rest.

CAT. NO. DESCRIPTION
124845
CF-1 Fraction Collector, 115V, with racks for 12-13mm tubes
24846
CF-1 Fraction Collector, 230V (continental europe), with racks for 12-13 mm tubes (CE)
Optional Accessories
124853
Replacement set of racks to hold up to 174 12 or 13 mm diameter tubes. This set is included with the fraction collector. Maximum tube length is 8 inches (200 mm). Using standard 13 x 100 mm test tubes the maximum fraction size is 10 mL. Tubes are Corning 99445-13.
124854
Set of racks to hold up to 116 10 to 16 mm diameter tubes. Maximum tube length is 8 inches (200 mm). Using standard 16 x 150 mm test tubes the maximum fraction size is 23 mL. Tubes are Corning 99445-16XX.
124855
Set of racks to hold up to 116 17 or 18 mm diameter tubes or mini-vials. Maximum tube length is 8 inches (200 mm). Using standard 18 x 150 mm test tubes the maximum fraction size is 27 mL. Tubes are Corning 9820-18.
124856
Set of racks to hold up to 42 28 mm diameter scintillation vials. Maximum tube length is 7 inches (175 mm). Scintillation vials have a typical capacity of 20 mL.
124858
Dust cover for fraction collector. Prevents contamination of your fractions by airborne dust and particulate matter. The dust cover can be installed and removed without disturbing any electrical or fluid connection.
124848
2-Way shutoff valve. This is primarily used when collecting radioactive or especially toxic materials. It stops the flow to the drop former when the tubes are moving as well as at the end of the run. This valve is also useful when collecting from gravity-flow columns since it can keep the column from running dry.
124849
3-Way diverter valve. This valve diverts the flow to a waste or recycle container when the tubes are moving, at the end of a run, or when directed by the peak separator. This valve is required when using the peak separator features of the fraction collector.
124874
Mast package. This package attaches two 50 cm long, 3/4 inch diameter masts (included with package) to the bottom of the fraction collector. These masts may be used to support small instruments or columns directly over the fraction collector, saving bench space. The mast package is required to support the 4 column adapter.
124876
4-column adapter. The 4-column adapter is used to simultaneously collect fractions from up to 4 columns. It can collect up to 29 fractions in 10 to 16 mm diameter tubes from each column. The 124874 mast package must also be obtained in order to use the 4 column adapter with the fraction collector.
123859
Volumetric collection cable. This cable is used to connect a CF-1 Fraction Collector to an MP-1 or MP-2 pump. This cable performs 2 functions; it stops the pump between tubes and at the end of the run and it allows the fraction collector to size fraction based on the amount of volume pumped. This latter feature is not especially useful unless you change the pump speed during a run. This cable cannot be used with the 124815 or 123449 cables or with the drop counter.
124815
Pump stop cable. This cable connects a CF-1 Fraction Collector to an MP-1 or MP-2 pump. This cable stops the pump at the end of a run. This cable cannot be used with the 123859 cable.
124865
Signal cable. This cable connects the CF-1 Fraction Collector to your detector. This cable carries only the detector signal information used by the peak detector. If you are not using the peak detector to separate peak from non-peak material you do not need this cable.
123449
Tube change cable. This cable connects the CF-1 Fraction Collector to a model 229 UV monitor. When connected by this cable, a small "tick" mark will be placed on the recorder trace for each tube change. This allows you to more easily determine which peak is in which tube. This cable cannot be used with the 123859 cable.
