Nov 03, 2020 · Sterile PTFE syringe filters are a good tool to sterilize non-sterile solutions or clarify sterile solutions, while the non-sterile PTFE syringe filters are used for common filtration and purification as well. You can draw the sample into the 0.45um syringe filter if you select the right hydrophilic syringe filter for your application.

Glass fiber filters are produced from borosilicate glass fibers and are typically used for pre-filtration. Membrane Pore Size. 0.45 µm membranes are used for clarification and particulate removal; 0.20 µm and 0.22 µm membranes can be used for filter sterilization and ultracleaning of aqueous solutions and organic solvents for HPLC

Jul 11, 2017 · HPLC prep using a stacked syringe filter. Syringe filtration often involves aspirating the sample, fitting a particle filter, and filtering into an autosampler vial. The vial is finally capped and transferred to an autosampler. This filtration process can be repeated dozens of time a day, depending on your laboratory workflow and HPLC capacity.

Three sizes: 150 mL, 500 mL and 1,000 mL. Low liquid retention funnel design. Available in 33 mm and 45 mm neck sizes to fit most glass and plastic media storage bottles. 45 mm neck sizes fit on Corning® glass 1395 bottles, to be used on 2L and smaller sizes only.

Filtration of aqueous or organic solutions. Resist most commonly used HPLC solvents. Hydrophilic discs made of noncharged, unreinforced Nylon 66 in 0.2 and 0.45μm pore sizes. Won't contaminate a sample with extractables. Autoclaved or sterilized by EtO. Thermal compatibility: ≤135°C (275°F)

Fortis C18. Use for general chromatographic methods requiring C18 chemistry, high efficiency, excellent peak shapes, wide pH range 1-12. UHPLC to prep scale particle sizes.

Typically, .45 microns is used to purify a solution containing high-concentration of particulate matter while .22 microns is used when sterilizing a solution (removing bacteria and viruses) and preparing gasses for HPLC. Syringe filters come in several diameter sizes which are selected depending on the volume of liquid needed to be filtered.

Transwell cell culture inserts were used as the donor chamber and 6-well culture plates (Corning Corp., Corning NY, USA) as the acceptor chamber. Two different membrane materials, polyester and polycarbonate membranes (Transwell, Corning Corp., Corning, NY, USA) separating the chambers were studied in order to evaluate the effect of the

Corning Filter Selection and Use Guide Choosing and using filters doesn't have to be complicated - Corning has simplified the process. Just follow the easy steps outlined in this 20 page guide to improve the selection and use of filters in your laboratory.

Syringe/Disc Filters The smaller conventional Corning® syringe disc-type filters (4, 15, and 25, 26 and 28 mm diameter) are used with syringes which serves as both the fluid reservoir and the pres-sure source. They are 100% integrity tested. The HPLC-certified non-sterile syringe filters

These Costar® Spin-X® centrifuge tube filters have a 0.45 µm pore NY membrane-containing filter unit within a 500 µL capacity polypropylene microcentrifuge tube. Nylon (NY) membranes are naturally hydrophilic, surfactant-free and offer the lowest extractables Ideal for removing bacteria, particles, or cells from liquids, HPLC sample

Hydrophilic PTFE Membrane Filters. Advantec MFS. Filter both aqueous and organic solvents Optically clear when wet Hydrophilic PTFE membranes are a thin, unsupported, highly porous film that offers maximum chemical and pH resistance to a broad range of aqueous and organic solvents. This membrane exhibits high flow rates with minimal.

Nylon membrane is hydrophilic and is a good choice for aqueous and/or aqueous-organic samples. The membrane offers good chemical resistance to most common HPLC solvents, however it has limited resistance to acids, bases, halogenated hydrocarbons, aldehydes and strong oxidising agents. The most common application is HPLC sample filtration.

Syringe/Disc Filters The smaller conventional Corning® syringe disc-type filters (4, 15, 25, 26, and 28 mm diameter) are used with syringes which serves as both the fluid reservoir and the pressure source. They are 100% integrity tested. The HPLC-certified non-sterile syringe filters are available with nylon, regenerated

The filter housing materials, as well as the filter membrane must be compatible with the solutions being filters. Polystyrene (PS) is used in the filter funnels and storage bottles for all of the Corning plastic vacuum filters. This plastic polymer should only be used in filtering and storing nonaggressive aqueous solutions and biological fluids.
