Design your FPLC system according to your purification task!
Complete solutions for FPLC (Fast Protein Liquid Chromatography) on a small footprint: AZURA® FPLC systems combine flexibility and reliability. The biocompatible/metal-free AZURA® FPLC is the perfect choice for your protein purification task.
Design your AZURA Bio purification system to your needs. Multiple functionalities such as automatic sample injection via autosampler, column switching, buffer and sample selection as well as fraction collection enable the user to automate the purification process. A range of different detectors let you keep track of your target molecules. A wide flow rate range and compatibility with columns from all vendors offer maximum flexibility. The intuitive software PurityChrom® combines all the advantages of a versatile purification software.
From simple to complex, from Lab to Pilot scale: Design your AZURA® FPLC system according to your purification task!
Because of their modularity, AZURA® Bio Lab devices can be flexibly arranged with each other to a bio purification system that matches your requirements. Accordingly, AZURA® offers a solution even for complex purification tasks like for example a 3-step purification process including the steps: 1. Simultaneous capturestepof up to 5 samples to shorten the time for sample loading 2. Sequential intermediate or desalting step via a second column 3. Sequential polishing or desalting stepvia a third column inlcuding fraction collection All of these steps can be perfectly managed by the FPLC software PurityChrom 6 including data signal triggered fractionation.
AZURA® Bio Lab allows you to create FPLC systems with highest independence. Just pick your modules and create the system yourself.

Size Exclusion (SEC)
Hydrophobic Interaction (HIC)
All in One
Size Exclusion Chromatography (SEC)
SEC, also referred to as gel permeation chromatography (GPC),separatesthe componentsby molecular sizewhile the sample is passing through the stationary phase (one step). The deciding factor is the pore size distribution of the stationary phase. However, it is not a sieving effect, but adiffusion effect, because large molecules are eluted faster than the small ones.
The smaller moleculescan better penetrate into the pores of the stationary phase and thusstay longer in the column than large molecules, which have less space for movement and therefore are more strongly entrained with the eluent. Therefore, the big molecules elute first.
Affinity chromatography is a multi-step process (binding, washing, elution) characterized by specific binding of the target molecules to the column material. Therefore, the ligand of the stationary phase must be matched to the target molecules. In a washing step, all non-specifically bound portions of the sample are removed. The subsequent elution step releases the target molecules.
Ion exchange chromatography separates molecules based on their total charge.
It is a competitive process in which target molecules and all molecules in the sample featuring a polarity of the same direction are first "nonspecifically" bound to the stationary phase and then gradually eluted (2 steps).
For example, a cation exchanger is used for target molecules with a positive overall charge.
The stationary phase itself is of opposite charge, that is negatively charged. Initial binding to the stationary phase occurs under low ionic strength conditions, i.e. the mobile phase with the sample has a low electrolyte content. The elution is achieved by a salt gradient. By increasing the salt concentration, proteins with a weak charge elute first, while at higher salt concentrations proteins with a strong charge elute later.
In protein purification processes different methods are usually combined in a more complex purification strategy. Multi-Method systems can be used to perform all methods used in your purification strategy on one system.
Choosing between a multitude of buffers and samples is essential when auomating a purification routine. To do so you can choose to add multipleinlet valvesto the system pump and sample pump to widen your selection.
Up to three valves can be combined in an FPLC module docking station. A combination between sample pump, small detector and valves in one docking station is also possible.
Within an FPLC purification differing sample sizes are common, ranging from microliter to liter. To handle the changing sample sizes one often switches between asample pumpand sample loops for sample injection. A multi-injection valve is perfect to do so in a lab system.
FPLC purifications are usually a multi step process. And each step relies on a specific column. To be able to switch between these columns fast and easy the column selection valve can be used in a lab system.
An outlet valve module can be used as a standalone fractionation valve or in combination with a fraction collector. Besides fraction collection the outlet valve can also be used to transform your standard Lab system into a two step purification system.
