Maximum separation effect with double pass over the magnetic plates. Automatic changeover for cleaning operation without process flow interruption. Powerful Rare Earth magnetic material. Self cleaning design. Dust-tight casing construction in reinforced Carbon Steel folded plates (optional Stainless Steel).
Magnetic separation of nucleic acids has several advantages compared to other techniques used for the same purpose. Nucleic acids can be isolated directly from crude sample materials such as blood, tissue homogenates, cultivation media, water, etc.
The first pair of balls was weakly magnetized and served to draw off any iron ore present. The second pair were strongly magnetized and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day. It is also used in electromagnetic cranes that separate magnetic material from scraps.
In this paper, the recent advancements of magnetic separation techniques based on magnetic materials in the field of sample preparation for biological analysis were reviewed. The strategy of magnetic separation techniques was summarized. The synthesis, stabilization and bio-functionalization of magnetic nanoparticles were reviewed in detail.
Advanced cell-based research requires cell isolation techniques in addition to cell culture. Magnetic-based separation can separate cells of almost any type from whole blood, bone marrow or buffy coat. Typically, CD antibodies or antigens are coupled to nanosized paramagnetic or superparamagnetic molecules.
Whilst separation techniques relying on gravitational forces have become relatively sophisticated in their application to biology the same is not true for magnetic separation procedures. The use of the latter has been limited to the few cells which contain paramagnetic iron.
We also provide demagnetising solutions that reverse the residual effects that magnetic separation has on the magnetic viscosity of ferrous slurries, to return the mineral stream to an acceptable viscosity for downstream processing standards. These demagnetising coils generate a magnetic field that alters magnetic orientation at 200 Hz.
Magnetic cell sorting using annexin-V microbeads can effectively separate apoptotic and non-apoptotic spermatozoa. The objective of the present study was to optimize the integration of magnetic cell sorting in standard sperm preparations and to correlate the effect of different sperm preparation procedures on apoptotic markers.
The outstanding examples of the magnetic cell separation application include the isolation of rare progenitor cells from the human umbilical cord blood and the use of mobilized peripheral blood as a substitute for bone marrow transplantation in patients who underwent irradiation and chemotherapy (Powles et al, 2000; Weissman, 2000).
