Flash- and Medium Pressure Chromatography



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

Pump flow rate: 1 to 250 mL/min
Max. pressure: 10 bar (Easy Synthesis), 50bar (Easy Extract)

Easy Synthesis and Easy Extract are two basic flash chromatography systems, which allow to optimize the separation efficiency compared to an open column separation by controlled flow rate and by the possibility of a gradient elution. For reproducible results different packed columns are available. More info

Pump flow rate: up to 250 ml/min
Max. pressure: 10 bar (X10), 50 bar (X50)

The Sepacore® X10 / X50 flash systems suit most demands for the purification of organic compound. The ready-to-use preparative chromatography systems with flow rates up to 250 ml/min delivers high efficiency separations at pressure ranges up to 10 (X10) or 50 bar (X50). The systems are equipped with 2 pumps for a binary gradient, a fraction collector and a UV/VIS detector (200 - 840 nm). More info

Flow rate: 2.5 - 250 ml/min.
Pressure range: up to 10 bar (C-601),
up to 50 bar (C-605)

No matter what the application in isocratic or gradient mode is, the modules provide a reproducible and pulse free flow solvent delivery due to its 3-piston pump head. The pump modules are easily upgradable according to your application and budget from isocratic to gradient or manual to computer control. More info

The UV/VIS detector C-640 is designed for analytical HPLC, preparative HPLC and flash chromatography. Due to its wavelength range of 200 - 840 nm, the instrument detects most compounds and saves time through simultaneous detection of 4 wavelengths.
For the detection of all non-volatile compounds, the Evaporative Light Scattering Detector (ELSD) C-650 is most suitable. Nevertheless, both models can be easily integrated in any system configuration. More info

The Fraction Collector C-660 collects the separated substances according to time, volume or peak in any type of tubes or vessels. Per run, up to 12 liters can be collected in a maximum of 240 glass tubes enabling high flow rates as well as long sequences. More info

The cartridger C-670 allows the simple and quick packing of cartridges in a range of 4 to 90 grams with any silica based material with particle size from 30 to 200 um. If required, a specific cartridge can be prepared by choosing your own silica and select the cartridge format (4 to 90 g). More info

BÜCHI Labortechnik AG
The empty cartridges are to be used for the reproducible packing with the cartridger C-670.

The prepacked cartridges come with different sorbents (Silica, C-18, Amine, Cyano, Diol, SCX-2) in particle size 40 - 63 um. Silica HP packed cartridges in particle size 15 - 40 um.

When purification must be scaled up, the glass columns offer great versatiltiy in terms of scale and separation requirements. The columns are available in a broad range of sizes: ID 15 - 100 mm and length 100 - 820 mm More info
