Whatman Puradisc micron syringe filters from Cytiva's offer a versatile solution for analytical sample preparation needs. They are a variety of options available to suit all labs needs, and are well-suited for routine syringe filtration of samples up to 100 mL for a range of applications, including high performance liquid chromatography (HPLC) and capillary electrophoresis (CE).
Polypropylene (PP) syringe filters are designed for aqueous or organic solutions that have high levels of debris and for difficult-to-filter solutions. It's a hydrophilic membrane with a wide range of chemical compatibility with organic solvents.
Cytiva's Whatman ™ Uniflo Syringe Filters are disposable filter units designed to provide clean filtrate from small volumes up to 100 mL. They are available in a variety of membrane choices with a polypropylene overmold housing.PES Membrane:Polyethersulfone membrane provides durability, high temperature resistance, good chemical compatibility and low protein absorption.
Jun 26, 2014 · After the discovery, researchers and labs competed to create the new filtration standard, arbitrarily defining their filters to be either 0.2 or 0.22 micron in pore size, roughly half the size of the old standard. What that means is, for the purpose of sterilization, 0.2 micron and 0.22 micron filters are indistinguishable.
choices with a polypropylene overmold housing. Whatman Uniflo syringe filters are available with: • 13 mm, 25 mm or 30 mm diameters. • 0.2 μm or 0.45 μm pore sizes • Sterile or non-sterile options • Laser etched printing on the filter for easy identification Filter media Nylon PES PTFE PVDF H-PTFE Aqueous and/or organic samples
pure, single-material-construction filter device with a broad range of solvent/chemical resistance. Polyethersulfone (PES) Membrane Considerations: This carefully selected Polyethersulfone membrane meets the special filtration requirements of durability, high temperature resistance, good chemical compatibility, and low protein adsorption.
A syringe filter (or wheel filter) is a single-use, membrane-based device used for the removal of particulate impurities from small (≤ 100 mL) liquid samples (Figure 1). Selected based upon the desired end application, disposable syringe filters are commonly used in labs for fast and efficient filtering, material purification, or even
a specific size syringe and take appropriate safety precautions not to exceed the recommended rating for the device used. If these limitations are exceeded, bursting of the device may occur resulting in loss of sample or personal injury. Pre-filter Media: The Whatman 25mm GD/X Syringe Filters contain
There are so many solvents and syringe filter/membrane materials that it can be tough to remember which combinations are safe and which are corrosive. These tables show five common syringe filter materials -- Cellulose Acetate (CA), Nylon, PES, PTFE, and PVDF -- and their compatibilities with 75 common solvents. Compatibility Tables Compatibility Grades
Polyethersulfone (PES) Hydrophilic membrane. Broad solvent compatibility. Suitable for filtration of aqueous and compatible organic solvents. Higher liquid flow than either PTFE or PVDF. Low in extractables. Low protein binding. Nylon/polyamide (NYL) Hydrophilic membrane. Resistant to a range of organic solvents. Suitable for use with high pH samples. Binds
with both solvent and aqueous compatibility. This medium provides a pure, single-material-construction filter device with a broad range of solvent/chemical resistance. Polyethersulfone (PES) Membrane Polyethersulfone membrane provides durability, high temperature resistance, good chemical compatibility, and low protein absorption.
Here is more information about our polyethersulfone PES disk filters. Manufactured and distributed under ISO9001 certification. The 50mm diameter housings are made of 100% polypropylene and thermally bonded. We do not use adhesives. The connections are both 7-13 mm stepped hose barb with the ability to accept a standard luer slip syringe as well.
Syringe Filters for Organic Solvents. Compatibility between your syringe filter’s media and the organic solvents you are filtering is of utmost importance when performing any type of application. Not all syringe filter membrane materials are recommended for all substances and chemical reagents. For example, some solvents may eat away certain
1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.
