Product Overview

Whatman VACUGUARD filters feature a high-performance hydrophobic PTFE membrane designed for critical filtration applications requiring absolute sterility and chemical compatibility. The 0.45?m pore size provides efficient retention of microorganisms while maintaining high flow rates, making these filters ideal for demanding laboratory environments. The PTFE membrane offers exceptional resistance to aggressive solvents, acids, and bases, ensuring reliable performance across diverse applications. Each filter undergoes rigorous quality control to guarantee low extractables and consistent pore size distribution. The robust construction prevents fiber shedding or membrane damage during use, while the color-coded housing enables easy size identification. Available in multiple diameters (50mm, 60mm, 150mm) and configurations (TF/AC, TF/D), these filters accommodate various filtration setups. The sterile packaging maintains integrity until use, with individual pouches allowing convenient single-use applications. Engineered for both manual and automated filtration systems, VACUGUARD filters deliver reproducible results with minimal sample loss, making them a preferred choice for research laboratories requiring precision and reliability in their filtration processes.

FAQs

1. What is the maximum operating temperature for these PTFE filters?

The hydrophobic PTFE membrane can withstand continuous operation at temperatures up to 130?C, with short-term exposure possible up to 260?C without compromising integrity.

2. Can these filters be used with organic solvents like acetone or methanol?

Yes, the PTFE membrane is fully compatible with all organic solvents, including aggressive ones like acetone, methanol, DMSO, and THF, without any chemical degradation.

3. How should these filters be stored to maintain their sterility?

Store the unopened filters in their original packaging at room temperature (15-30?C) away from direct sunlight and moisture. The sterile barrier remains intact until the pouch is opened.

4. What’s the difference between TF/AC and TF/D configurations?

The TF/AC version features an acrylic copolymer support for enhanced mechanical strength, while TF/D uses a polypropylene support that offers broader chemical compatibility with highly aggressive solvents.

5. Are these filters suitable for filtering compressed air in cell culture hoods?

Absolutely, the hydrophobic nature of PTFE makes these filters particularly effective for sterile air filtration in biosafety cabinets and cell culture environments, preventing microbial contamination.
