BÜCHI Labortechnik AG BISCHOFF Chromatography GmbH

Preparative Chromatography (HPLC)



BÜCHI Labortechnik AG
Pump flow rate: 1 to 200 mL/min
Max. pressure: 200 psi (14 bar)
Gradients: linear, step, isocratic, 4 solvent binary
ELSD, UV-Vis detector

The Reveleris® X2 flash chromatography system is able to detect chromophores, non-chromophores, and visible sample components from mg to kg quantities by synchronizing the signals from up to four different detectors, including ELSD and UV-Vis detectors, to optimize the number of fractions and to ensure maximum purity. Recoveries are maximized by only directing 50 μL/min or less of the sample to ELSD. More info

The Reveleris® PREP purification system combines flash chromatography and preparative HPLC capabilities in a single instrument. The user can easily switch between flash and preparative HPLC modes with a single touch on the screen. Both flash cartridges and preparative HPLC columns can be used. The system is equipped with 3-channel variable UV-Vis and ELS detection to detect chromophores and non-chromophores. More info

The Alltech® 3300 ELSD simplifies analysis of difficult compounds such as pharmaceuticals, impurities, fatty acids, or polymers. This system was developed to improve baseline stability and detection sensitivity compared to refractive index (RI), and to use ELSD in parallel with UV/Vis and MS for maximum structural and concentration information. As a result, it obtains a more accurate representation of sample mass than UV/Vis. More info

The new Bischoff compact pump model 3350 convinces by its compact dimensions and low maintenance concept. With an accuracy flow rate at high pressure up to 60 MPa from 1µl up to 40.00 ml/min the pump is highly qualified for all areas of modern LC and dosing applications. The dosing / metering pump can be used in isocratic or gradient mode, for the latter a second pump is required. More info

The PrepChrom C-700 is a software driven, all-in-one purification system, which allows to use preparative HPLC columns as well as flash cartridges or glass columns. The detection is done at once with a DAD and an optional ELSD detector. Up to quaternary gradients can be generated with a max. flow of 250 ml/min. at max. 100 bar. More info

The Buchi-Grace cartridges come in a broad range of sizes to cover different stationary phases, particle sizes and geometries. They convince with spherical particles for fast separations and high loadings, an increased fraction purity and a high resolution of separation. Moreover, the wide choice of hardware formats guarantees compatibility with all flash systems including ISCO, Interchim, Agilent and YMC. More info

BISCHOFF Chromatography GmbH
The Bischoff HPLC columns come in a broad range of lengths, internal diameters and materials to cover a wide range of separations. If, however, no column meets the demanded separation requirements, there is also the option to fabricate according to customer specifications. Apart from filling materials of well-known manufacturers, we also offer our own substances such as ProntoSIL, HiPAK and PolyEncap. Moreover, a refill service is available with ProntoSIL as well as materials of other manufacturers. More info
