Cytiva's Whatman Puradisc line is a comprehensive syringe filter portfolio used in a variety of applications. Cytiva also offers high-performance GD/X syringe filters with a multi-layer glass fiber prefilter for filtering larger volumes of harder-to-filter samples. Hydrophilic PES membranes are designed for stability in low pH, have low levels
Sterile PES Syringe Filters is a fast, convenient and reliable small-volume sample filtration device that is routinely used in laboratories. The syringe filters are widely applied in the biotechnology industries for the purification of enzymes and peptides. The filter processing capacity is from 2mL to 5000mL.
Mar 04, 2018 · 1.Get the most appropriate filter to use. 2.Draw 1ml of air followed by your sample in a sterile syringe. 3.Eject 1ml of the sample in a waste container. 4.Eject the rest of the sample in a clean vial for storage. 5.Push the air you initially drew into the same vial. This step will push out the remaining fluid and will reduce the held up volume.
Description of Disposable PES Micron Syringe Filters. Disposable PES micron syringe filters have strong hydrophilicity, narrow pore distribution, and precise pore size, low protein adsorption has good permeability, no pollution to the sample, small resistance, fast filtration speed, and good resistance chemical; 0.45 um PES syringe filter has a very good effect on the filtration and
MS® PES syringe filters are purpose-built with features designed to bring the highest levels of performance and purity to your research. We incorporate a variety of membranes to offer separation and purification solutions for the majority of your laboratory needs. PES (Polyethersulfone) – low affinity for proteins and extractable with
Sep 28, 2016 · Other, filter holder (in-line) types allow you to regain your filter (Figure 1). Syringe filters normally use membrane type filters which have a specific particle size cut off (e.g. 0.45 μm). Syringe filters are also available for the filtration of gases and for the removal of bacteria from a sample.
Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents. For samples composed of acids and bases, hydrophilic PTFE membrane syringe filters and PES membrane syringe filters may be considered.
Nest syringe filters have pore size either 0.22µm or 0.45µm, and diameter 13mm or 25mm, with membrane materials either with PES or PVDF membranes. For sample volumes of 2mL to 100mL. Retention volume <115µL. Maximum operating temperature: 100°C autoclave at 125°C for 15 min. Maximum operating pressure approximately 100 ps.
Nylon membrane syringe filters may not be suitable for all samples and are ideal for near neutral pH aqueous solutions and compatible nonaqueous solvents. For samples composed of acids and bases, hydrophilic PTFE membrane syringe filters and PES membrane syringe filters may be considered.

A variety of membranes are available to meet your needs: Polyethersulfone (PES) – low protein binding and faster flow rates; surfactant-free cellulose acetate (SFCA) – lowest protein binding; polytetrafluorethylene (PTFE) – chemical resistance; regenerated cellulose (RC) – best choice for DMSO compatibility; Nylon (NY) – hydrophilic, surfactant-free, and lowest extractable. 100%
Feb 17, 2020 · Attach the filter securely to the syringe using a twisting motion. Pour the sample solution from the unpreserved fill bottle into the top of the syringe leaving space for the plunger. Reinsert the plunger. Note: The individually packed sterile syringe filter can be held in the original package to minimize contamination while attaching the syringe.

Sterile PES Syringe Filters are commonly used for water, chemical and high temperature liquid filtration. They provide superior thermal stability and low protein binding characteristics. They are also inherently hydrophilic. Tisch Scientific stocks Sterile PES Syringe Filters in Cincinnati, Ohio and can ship in one business day!
Therefore, it is very important to scientifically master how to use the syringe filter. 1. Syringe filter sterilization, including gas filters or liquid filters, should be tested for integrity before and after use in accordance with the integrity test procedures for sterile filters. 2. After the integrity test is over, the membranes and filters used for aseptic production need to be sterilized. 3.
