Chromatography Instruments

Spectrum Chromatography manufactures a complete set of instruments for liquid chromatography. These include Peristaltic Pumps, a Fraction Collector, a fixed wavelength UV Detector, a strip-chart recorder, and a Solvent Recycler.

Spectra/Chrom® CF-2 Fraction Collector
The CF-2 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" OD tubing and 1/16" ID tubing.

Model 280 UV Detector
The New Spectra/Chrom Model 280 UV Detector is a compact high-performance detector for both hplc and low-pressure liquid chromatography. By using a dual beam spectrophotometer, the Model 280 UV detector can subtract even rapidly changing baselines. It includes a dual 5 mm pathlength flow cell and filters for both 254 and 280 nm.

MP-1 & MP-2 Peristaltic Pumps
Spectrum manufactures 2 different peristaltic pump drives and a variety of pump heads. These allow for the optimal combination to be selected for each application. The flow rate range available is from 0.03 ml/min to 2280 ml/min.
Each pump drive can power up to 3 pump heads.

Spectra/Chrom Chart Recorder
The Spectra/Chrom Chart Recorder is an inexpensive strip-chart recorder suitable for many laboratory uses. It is available in both single and dual-pen configurations. It is an ideal complement to our Model 280 UV Detector.

S-3 Solvent Recycler
The Spectra/Chrom S-3 Solvent Saver System is used in both HPLC and low-pressure liquid chromatography to reduce solvent consumption. The solvent in between peaks in these applications is usually sufficiently pure to be recycled as eluent without additional processing.
