After the successful launch of the Metcell crossflow system, Membrane-Extraction Technology (Met) has introduced a variant form that is available in Hestelloy.
After the successful launch of the Metcell crossflow system, Membrane-Extraction Technology (Met) has introduced a variant form that is available in Hestelloy.
The system offers enhanced chemical resistance compared with the previous high-pressure filtration system, thus permitting an even greater spectrum of possible chemical nanofiltration and reverse osmosis separation reactions.
The Metcell crossflow system is available in two versions, consisting of the core Metcell system (in Hastelloy), in conjunction with either the three 64mm crossflow cells or the two 100mm crossflow cells assembly.
The range of equipment is designed for applications where high-pressures are required to carry out the desired membrane separation, for example nanofiltration or reverse osmosis.
Where the stainless steel Metcell crossflow system covers most of the secondary applications for a small-scale crossflow system to carry out more tests in less time identified, the Hastelloy system is designed to withstand applications of a more corrosive nature, such as reactions in a high chloride concentration environment.
As the Hastelloy crossflow system encompasses core components from a Metcell system, the dead-end filtration capability of the Metcell is completely retained in addition to carrying out crossflow filtration with up to six crossflow cells in series.
The cells feature the same clamped design as the Metcell to allow quick and easy membrane changeover.
All components of the assembled Metcell crossflow system are pressure rated to a minimum operating pressure of 69 bar and conform to European Pressure Directive (97/23/EC).
The Key advantages of the Metcell crossflow system include: a choice of crossflow or dead-end filtration; greater flexibility now possible, in terms of membrane area per filtration volume; run more tests per experiment, for example, different membranes in each MET crossflow cell; and generate results that provide a better prediction for scale-up.
The Met gas unit (provided as standard with the Metcell, and to new users with the Metcell with Metcell crossflow system) allows safe and simple operation of this high-pressure system, through connection to a gas cylinder.
Also incorporated is a connection port for an HPLC pump.
This allows solutions to be fed into the system without opening the cell, which is particularly useful when solutes are oxygen/moisture sensitive or when continuous operation is required.
Typical applications include: heavy metal removal Memsorb technology; solvent exchange Memsolvex technology; natural product fractionation and solvent separation; enatiomer separation; product purification, impurity removal and rapid product concentration; solvent and catalyst recovery and reuse; and membrane testing for ultrafiltration, nonfiltration and reverse osmosis The Metcell crossflow system has already been sold to customers in the UK and USA.
The new Hastelloy variant is raising interest and complimentary feedback among several major blue chip companies in the UK, USA, and Europe.
