Product Overview

The Whatman Uniprep syringeless filter is a high-performance filtration solution designed for seamless sample preparation in laboratories. Available in multiple membrane types?PVDF, NYL, PTFE, and GMF?these filters cater to diverse filtration needs, from protein and nucleic acid work to solvent and aqueous sample processing. The 0.2?m and 0.45?m pore sizes ensure effective removal of particulates, bacteria, and contaminants, making them indispensable for HPLC, GC, and general lab applications. Each filter unit is pre-assembled with a luer-lock inlet and outlet, eliminating the need for syringes and reducing the risk of cross-contamination. The PVDF membrane offers low protein binding, ideal for biological samples, while the NYL membrane provides broad chemical compatibility. PTFE filters excel in aggressive solvent filtration, and GMF (glass microfiber) variants are perfect for pre-filtration of viscous or particle-laden samples. The sterile, single-use design ensures consistency and reliability, minimizing sample loss and maximizing throughput. Whether used for routine lab tasks or specialized research, these filters deliver precision and convenience, streamlining workflows without compromising on quality.

FAQs

1. What is the difference between PVDF and NYL membranes in these filters?

PVDF membranes are hydrophobic and ideal for protein and nucleic acid applications due to low binding properties, while NYL membranes are hydrophilic and offer broad chemical compatibility for aqueous and organic solvents.

2. Can these filters be used with aggressive solvents like DMSO or acetone?

Yes, the PTFE membrane variant is chemically resistant and suitable for aggressive solvents, including DMSO, acetone, and other organic compounds.

3. Are these filters compatible with standard HPLC vials?

The luer-lock design allows direct connection to HPLC vials or tubing, ensuring seamless integration into existing lab setups.

4. How should these filters be stored to maintain sterility?

Store the filters in their original packaging at room temperature, away from direct sunlight and moisture, to preserve sterility until use.

5. What alternatives are available if I need a larger pore size?

For pre-filtration or larger particle removal, consider glass microfiber (GMF) filters or depth filters, which are designed to handle higher particulate loads.
