The lectin solution used was 1 mg/mL conA in B, which was filtered with a 0.45 µm cellulose acetate syringe filter. Membrane Surface Modification Up to 10 membranes were modified at one time; however, reaction amounts are reported on the basis of one 47 mm membrane.
Regenerated cellulose membranes are solvent resistent and hydrophilic. 0.45 µm pore sizes are mainly used for HPLC sample preparation. This membrane type is resistent versus most solvents, as well as aqueous solutions with a pH from 3 to 12 and temperature stable up to 200° C.
Membrane filters have a known uniform porosity of predetermined size (generally 0.45 µm ) sufficiently small to trap microorganisms. Using the membrane filter technique, sample is passed through the membrane using a filter funnel and vacuum system. Any organisms in the sample are concentrated on the surface of the membrane.

Membrane processes are increasingly used for removal of bacteria, microorganisms, particulates, and natural organic material, which can impart color, tastes, and odors to water and react with disinfectants to form disinfection byproducts. As advancements are
Pall Laboratory’s sterile syringe filters with 0.2 µm membranes remove bacteria, microorganisms, and fungi that can contaminate valuable cultures. Protein Purifi cation Higher cell densities can be diffi cult to filter downstream due to bioburden, which can cause premature filter clogging.

A 33 mm diameter sterile syringe filter with a 0.45 µm pore size hydrophilic Polyethersulfone (PES) membrane. Comes in a
They are available either with an asymmetric 0.22 or 0.45 µm polyethersulfone membrane that provides the fastest flow rates and ensures lowest protein binding as well as low extractables. The 0.22 µm version is ideal for sterile filtration of cell cultures, buffers and aqueous solutions; the 0.45
Bottle-top filters are used in research laboratories for sterilization or laboratory fluid clarification. The attachments are ideal for use with cell culture and serum-containing media, and asymmetrical hydrophilic membrane styles provide high flow rates.
Membrane filters are thin filters that are made of cellulose. They can be used for sterilization during injection by placing the membrane between the syringe and the needle. Seitz filters are usually made of asbestos. They are pad-like and thicker than membrane
Apart from the GF membrane, two pore sizes for each membrane were tested: 0.20 and 0.45 μm pore size. The GF membrane had a pore size of 1.2 μm (the lowest pore size for this type of filter). Samples were prepared in 250 mL volumes and were either left unfiltered (control) or filtered using a syringe fitted with the relevant filter type and size.
Filtration is an integral piece of nearly every workflow of every lab. Whether its cell culture, protein research, water testing, bioprocess design, or QA/QC testing of beverages – filtration will play a role in your lab’s daily routine and Thermo Fisher Scientific has the tools you need.
Yes, you can filter serum with Millipore Express membrane. The Express membrane was designed for this application and offers fast filtration time. Millipore Express is available in a large number of filter devices including Millex syringe filters, Stericup and Steritop vacuum devices, Sterivac for large volumes of media and Steriflip for 50 mls.
Syringeless and Syringe Filters Syringe filters and membranes for the removal of interfering materials and fine particles prior to injection; includes filters both with and without syringes; suitable for both aqueous and aqueous-organic samples; often constructed from PVDF or PTFE.
Titan3 and Target2 syringe filters provide high-quality filtration solutions in the sample preparation process. Available in a variety of sizes & membranes. Next Generation Measuring Technologies
