Syringe Filters Hydrophilic PES 0.22µm 13mm Disc 100pcs Non‑Sterile

Description

Product Overview

Zoomto presents a premium line of hydrophilic syringe filters designed for demanding laboratory environments. Each filter incorporates a polyethersulfone (PES) membrane that offers a precise 0.22 µm pore size, ensuring the removal of sub‑micron particles while maintaining a high flow rate. The disc diameter of 13 mm fits standard Luer‑lock syringes, providing a secure threaded connection that eliminates leakage and cross‑contamination. Constructed from chemically resistant PES, the filters tolerate a broad spectrum of solvents, strong acids, and bases, making them suitable for diverse analytical methods such as high‑performance liquid chromatography (HPLC) and gas chromatography (GC). The non‑sterile, barreled‑packed configuration supplies 100 filters per package, delivering cost‑effective, high‑throughput filtration for routine sample preparation.

Key specifications include a compact 2 × 2 × 2 inch package size, a lightweight 3.2 oz net weight, and a robust Luer‑lock interface that resists accidental disconnection during high‑pressure operations. The PES membrane’s hydrophilic nature minimizes protein adsorption, preserving sample integrity and reducing background noise in analytical results. Additionally, the filters are autoclave‑compatible, allowing for repeated sterilization cycles without compromising membrane performance.

Usage

These syringe filters excel in a variety of laboratory applications. In pharmaceutical research, they efficiently remove particulate matter from drug formulations, ensuring compliance with stringent purity standards. Environmental testing laboratories benefit from the filters’ ability to process large volumes of water and soil extracts, capturing contaminants before instrumental analysis. In academic settings, the filters support teaching labs by providing reliable, reproducible results for student experiments involving organic solvents, acidic or alkaline solutions, and complex mixtures.

Because the PES membrane exhibits low protein binding, the filters are ideal for biologics work, where preserving the native state of proteins and peptides is critical. The 13 mm disc size aligns with most standard syringes, enabling seamless integration into existing workflows without the need for additional adapters. Users can confidently employ the filters in high‑pressure HPLC systems, where the Luer‑lock design maintains a tight seal, preventing sample loss and ensuring consistent flow rates.

For high‑throughput screening, the 100‑piece pack reduces the time spent on inventory management, allowing laboratories to focus on data generation rather than consumable logistics. The non‑sterile nature of the product does not impede its performance in applications where sterility is not a prerequisite, such as chemical synthesis, analytical method development, and routine quality control.

Why Choose Us

Zoomto’s commitment to quality is reflected in every aspect of these syringe filters. The PES membrane is manufactured under strict quality‑control protocols, guaranteeing uniform pore size distribution and consistent filtration performance across each batch. Our filters undergo rigorous testing for flow rate, retention efficiency, and chemical compatibility, ensuring they meet or exceed industry standards for laboratory filtration.

Unlike many generic alternatives, our filters feature a unique threaded Luer‑lock interface that provides a secure, leak‑free connection even under elevated pressures. This design minimizes the risk of sample contamination and protects analytical instruments from particulate damage. The filters are also designed for durability; the housing resists cracking and deformation, extending the usable life of each unit.

FAQ

What solvents are compatible with these PES syringe filters?

The PES membrane is resistant to a wide range of solvents, including methanol, acetonitrile, dichloromethane, as well as strong acids (e.g., HCl, H₂SO₄) and bases (e.g., NaOH). This makes the filters suitable for most HPLC and GC sample preparation workflows.

Can the filters be autoclaved?

Yes, the filters are designed to withstand standard autoclave cycles (121 °C, 15 psi) without compromising membrane integrity or flow performance, allowing for reuse in non‑sterile applications.

Are these filters suitable for protein analysis?

Absolutely. The hydrophilic PES membrane exhibits low protein adsorption, preserving the native state of proteins and peptides during filtration, which is essential for accurate bioanalytical measurements.

What is the maximum pressure these filters can handle?

These syringe filters are rated for pressures up to 4 bar (≈58 psi), making them compatible with most HPLC systems and high‑pressure sample preparation protocols.

How should the filters be stored to maintain performance?

Store the filters in a cool, dry environment away from direct sunlight. Keep the packaging sealed until use to protect the membrane from moisture and contaminants.
