Frequently Asked Questions

What is the Whatman 6779-0404 Puradisc syringe filter used for?

This syringe filter is designed for small-volume sample filtration and clarification, particularly for applications like HPLC sample prep, capillary electrophoresis, protein solutions, and UV/Vis analysis. Its compact size makes it ideal for limited sample volumes.

What membrane material is used in this filter?

The filter uses a polyvinylidene difluoride (PVDF) membrane, known for low protein binding and strong chemical compatibility, making it suitable for biological samples as well as many organic solvents.

What sample volume is suitable for a 4 mm syringe filter?

The 4 mm Puradisc filter is designed for very small sample volumes (typically up to ~2 mL), making it ideal for micro-scale filtration tasks where minimizing sample loss is important.

What does the 0.45 µm pore size indicate?

A 0.45 µm pore size is suitable for general clarification and removal of fine particulates, offering a balance between filtration efficiency and flow rate. It is commonly used for non-sterile filtration workflows.

What are the key design features of Puradisc 4 syringe filters?

These filters feature a polypropylene housing, Luer-lock inlet and Luer outlet connections, and a compact 4 mm diameter design, providing leak-free operation and efficient filtration with low hold-up volume.
