Description
Specifications:
Hydrophilic PVDF membrane (Durapore®) — low nonspecific binding and broad chemical compatibility.
0.45 µm pore size — efficient removal of fine particulates and micro-contaminants.
47 mm diameter round filter discs — fits standard laboratory filtration devices.
High flow rates: > 2.6 mL/min/cm² (water) and ~ 4 L/min/cm² (air) for efficient throughput.
Low extractables (≈ 0.5 % gravimetric) for cleaner filtrates.
Non-sterile — suitable for general lab applications.
Plain white surface for unobstructed filtration.
Applications:
Clarification of aqueous, biological, and buffer solutions prior to analysis.
Sample preparation ahead of instrumental analysis (e.g., UV-Vis, HPLC).
Filtration of reagents and solvents in chemical and life sciences labs.
Pre-filtration step before sterile filtration workflows.

FAQ:
Q: What is the pore size of the HVLP04700 membrane filter?
A: The HVLP04700 membrane has a 0.45 µm pore size, suitable for capturing fine particulates in liquid samples.
Q: Is this membrane hydrophilic or hydrophobic?
A: It’s hydrophilic, meaning it readily interacts with and filters aqueous solutions.
Q: What is the material of the membrane?
A: Made from PVDF (polyvinylidene fluoride) known as Durapore® membrane with broad chemical compatibility.
Q: Can these filters be used for sterile filtration?
A: These discs are non-sterile; they are best for general filtration prior to sterile steps or analytical use.
Q: What size filtration equipment can this fit?
A: Designed for 47 mm diameter filter holders and compatible lab devices.
