PTFE Syringe Filters Hydrophobic 25mm 5μm by Allpure Biotechnology

Description

Product Overview

Allpure Biotechnology’s PTFE syringe filters are engineered with a hydrophobic polytetrafluoroethylene (PTFE) membrane that provides exceptional chemical resistance and a low surface energy that repels water-based liquids while allowing non‑aqueous solvents to pass freely. The filters are available in a 25 mm diameter format with a 5 μm pore size, delivering a rapid flow rate of 100‑150 mL per minute, which is significantly higher than traditional 0.22 μm or 0.45 μm filters. This high throughput makes them ideal for laboratories that need to process large volumes of samples quickly without sacrificing filtration quality. The PTFE membrane is manufactured under strict Japanese quality control standards and is certified to ISO 9001, ISO 13485, and CE, ensuring consistent performance across every batch.

Technical specifications include a pack of 100 filters per case, a weight of 11.36 ounces per package, and dimensions of 6.57 × 4.49 × 3.11 inches. The product model number AP‑PTFE1N5 was first released on August 7, 2019 and has earned a five‑star rating from six verified customers, reflecting its reliability and ease of use. The filters are compatible with standard 1 mL, 5 mL, and 10 mL syringes, and they can be used with a wide range of solvents, including organic acids, bases, and aggressive reagents, making them a versatile choice for any laboratory filtration need.

Usage

These PTFE syringe filters are designed for demanding laboratory environments where rapid, reliable filtration of non‑aqueous solutions is essential. Typical applications include sample preparation for high‑performance liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS) where removal of particulate matter and protection of analytical columns are critical. The hydrophobic nature of the membrane also makes the filters suitable for aseptic filtration of solvents used in cell culture, vaccine production, and biopharmaceutical processes, where contamination control is paramount. Because the filters can handle aggressive chemicals without degradation, they are frequently employed in research labs working with strong acids, bases, and organic solvents such as acetonitrile, methanol, and dimethyl sulfoxide (DMSO).

In addition to analytical chemistry, the filters are valuable in industrial quality‑control settings for testing raw materials, intermediates, and finished products. Their robust construction allows for repeated use in high‑throughput workflows, and the 100‑piece pack ensures that laboratories have a consistent supply for routine testing schedules. Users appreciate the ease of installation—simply attach the filter to the syringe tip, draw the sample, and push the plunger to achieve clean, particle‑free filtrate in seconds. The filters also perform well in field‑based applications, such as environmental monitoring, where portable syringe filtration is required for on‑site sample cleanup before laboratory analysis.

FAQ

What types of solvents can these PTFE syringe filters handle?

The filters are compatible with a broad spectrum of non‑aqueous solvents, including organic acids, bases, and aggressive reagents such as acetonitrile, methanol, dimethyl sulfoxide (DMSO), chloroform, and many others. Their hydrophobic PTFE membrane repels water, making them especially suitable for filtering solvent‑rich samples without risk of membrane degradation.

Can the filters be used for aseptic filtration in biopharmaceutical processes?

Yes. The hydrophobic PTFE membrane provides an effective barrier against microbial contamination while allowing sterile solvents to pass. This makes the filters ideal for aseptic filtration steps in cell culture media preparation, vaccine formulation, and other biopharmaceutical workflows where sterility is critical.

How do I ensure the correct filter size and pore size for my application?

Select the 25 mm diameter filter when using standard 1 mL, 5 mL, or 10 mL syringes. For applications requiring finer particle removal, the 5 μm pore size offers a good balance between flow rate and filtration efficiency. If you need even finer filtration, consider a 1 μm version of the same product line, which is also available from Allpure.

What is the recommended storage condition for these filters?

Store the filters in a cool, dry place away from direct sunlight and strong chemicals. The sealed packaging protects the PTFE membrane from moisture and contamination, preserving performance for the duration of the product’s shelf life.

What should I do if I encounter a clogged filter during use?

If a filter becomes clogged, first verify that the sample does not contain particles larger than the filter’s rated capacity. Pre‑centrifuging or using a larger pore size filter (e.g., 5 μm instead of 1 μm) can help prevent clogging. If clogging persists, replace the filter with a new one from the same pack, as each filter is designed for single‑use applications to ensure optimal performance.
