网页The PSM series plasma separation membrane developed by Cobetter is a new type of plasma separation filter, which is specifically developed for POCT diagnostics. It can quickly separate plasma from whole blood without hemolysis and no pre-treatment is required. The final reaction sample of POCT (point-of-care-testing) is mainly plasma.
网页If the membrane does not have a substrate, it is bio-directional and either side can be used as the inlet. If it has a substrate, the substrate layer will be more coarse and ridged than the membrane side. The membrane side would be the inlet and the coarse substrate side the outlet. The solvent should enter the inlet side of the membrane first.
网页Available mesh sizes are from 1 to 500 micron as well as membranes are available from 0.02 to 10 micron). Our mesh or tubular filters are used for particle retention (size of retained particles is depending on the media used). Especially in a blood transfusion line, the mesh or tubular filter with its 200µm mesh becomes a barrier for blood clots.

网页Upstream blood sample filter at a microfluidic chip/lab on a chip As the occupancy and reputation increases, Cobetter has developed various solutions of surface treatment for the plasma filtration membrane, indicating our capability of customizing plasma separation membrane product into a variety of filters according to every single specific requirement
网页2007年8月31日 · This paper presents development of a parylene membrane microfilter device for single stage capture and electrolysis of circulating tumor cells (CTCs) in human blood, and the potential of this device to allow genomic analysis. The presence and number of CTCs in blood has recently been demonstrated to
网页Filtration capacity: 0.5 µm Connecting diameter: 47, 50, 25 mmedge. Non-sterile, gridded membrane filters can be used for colony counting, particle testing and microscopy. Connecting diameter: 25, 47, 50 mm premium range of membrane filters and syringe filters to accommodate a variety of samples matrices for sample preparation and testing
网页2016年10月25日 · With experience extending as far back as 1965, Alfa Laval's specialists can answer the question in detail. Membrane filtration process is a physical separation
网页2015年12月11日 · Blood filtration is performed by hemodialysis membranes, leukocyte removal filter, and plasma separation membranes. Blood is composed of plasma solution and blood cells. Several valuable proteins such as immunoglobulin, factor VIII, factor IX, albumin, vitronectin, etc. are contained in plasma solution. Blood cells are erythrocytes
网页The membrane thickness is about 20-45 microm, and the length is 160-250 mm. The walls of the hollow fibers function as the dialysis membrane. Various materials, including cellulose-based materials and synthetic polymers, are used for dialysis membranes. This paper reviews blood purification, hemodialysis and dialysis membranes.
网页A Plasma or serum separation membrane that enables omitting centrifugal separation, is free from hemolysis attributed to destruction of red blood cells and realizes easy and rapid separation of plasma or serum from blood; and a filter
网页Membrane filtration technology provides an alternative to centrifugation. The patient's blood is pumped through a parallel-plate or hollow-fiber filter at a continuous flow rate, typically 50 to 200 mL/min (see Fig. 12-1B ). The membranes usually have pores of 0.2- to 0.6–μm
网页2011年9月7日 · Comparison between the SEM images of a non-coated membrane (Fig. 6d) and a heparin pre-coated membrane (Fig. 6e) after exposure to lightly heparinized (~300 IU/L) sheep’s blood (Hct = 39%) indicated a significant decrease
