Cosmospin Filter. Cosmospin filters are used to remove fine particles and precipitates from samples by centrifugation. They utilize Omnipore hydrophilic PTFE membrane filter, which has a wide range of chemical resistance. Cosmospin filters are the best choice for HPLC sample filtration.
Red PTFE (Hydrophilic) Syringe Filters, 0.22 µm, 25 mm. PerkinElmer. Hydrophilic PTFE syringe filters have broad chemical compatibility and high pH resistance and are optically clear when wet with water. They are versatile filters for use with aqueous and aggressive organic solvent-based solutions and are especially ideal for HPLC sample
7/8/2018 · Membrane-sample Compatibility It’s easy to overlook membrane compatibility when picking out your filter or device for your sample filtration. Good membrane-sample compatibility supports efficient filtration and minimizes resistance, while poor compatibility might result in backpressure, ineffective filtration, or even chemical attack of your membrane, leading to contamination of your filtrate.
Example:Filter needed for the apparatus fitting diameter size of 13mm Particle size (0.45um) , chemical compatibility (using Acid), and the membrane needed (hydrophilic) You will be able to find for example : PTFE Membrane filter with 0.45um pore diameter of 13mm
RC also has a broad solvent compatibility. Together with PTFE, RC is a useful general-purpose option to have on-hand. Extractables are a common symptom of membrane-sample incompatibility and affect sensitive downstream analytical techniques, such as .
PTFE membrane filters have excellent chemical compatibility (pH 1 to 14), so they are also used to filter solvents and acids, to which other types of filters are not resistant. Moreover, they can also be used for filtration of aqueous solutions, but due to their hydrophobic properties they must be pre-moistened with ethanol or methanol before filtering aqueous solutions of the medium.
The main application of these membrane filters ist the filtration of air, gases and chemicals. PTFE membrane filters have an excellent chemical compatibility (pH 1 to 14), so that they are also used for the filtration of solvents and acids, to which other filter types are not resistant.
PTFE membrane filters are strong and resistant to acids, bases, and solvents, and stable at high temperatures. With their low background and low tare mass they are ideal for gravimetric or aerosol/gas/vapour sampling. They are also available in preloaded, leak
Laboratory filter membranes, also known as cut disc membranes, are used in conjunction with filter holders and other hardware in a variety of applications including prefiltration, solvent filtration, sample clarification, sterilizing filtration, air monitoring, particle collection and analysis, and other biological and environmental applications.
