Performance & Design

These high-performance 0.22 μm PES syringe filters are engineered for laboratory analysis and sample preparation where accuracy, repeatability, and reliability are essential. The hydrophilic PES membrane supports fast flow rates and low protein binding while effectively removing particulates and microorganisms that can interfere with analytical results.

Advanced welding technology ensures a solid, leak-resistant housing structure, minimizing bypass risk and maintaining consistent filtration integrity during use. The compact 13mm format reduces hold-up volume and product loss, making it ideal for small-volume filtration applications.

Recommended Filtering Volume (Guidance Only)
Under typical laboratory conditions, these 13mm 0.22 μm PES filters are commonly capable of processing approximately 10 mL or more when used with most peptides, small proteins, and similarly prepared aqueous laboratory solutions. Filtration capacity may be reduced when working with higher-concentration solutions, more complex matrices, viscous preparations, or larger molecular-weight species that increase membrane loading or binding.
This guidance reflects general laboratory usage observations and is provided as a practical reference only. Actual throughput will vary depending on solution composition, concentration, viscosity, and technique, and should not be interpreted as a guaranteed performance threshold.

Manufactured using hydrophilic polyethersulfone (PES) membrane and medical-grade polypropylene housing, these sterile, individually wrapped filters provide consistent, reliable filtration while maintaining excellent chemical compatibility across a wide range of laboratory solutions.

Chemical Stability

PES membranes offer excellent chemical stability and maintain filtration performance across a broad range of solvents and laboratory reagents, supporting dependable use in diverse analytical environments.

Packaging

Each filter is sterile and individually wrapped to preserve cleanliness and convenience, making them ready for immediate use in controlled laboratory settings.

Applications

Suitable for laboratory analysis, sample preparation, and general small-volume filtration tasks where dependable, high-efficiency particulate removal is required.
