Filtration Insight: Membrane Selection & Pore Integrity

Selecting the proper polymer membrane prevents dissolution and extractable contamination. 0.22μm grades provide biological sterility, while 0.45μm grades clarify solutions and culture buffers efficiently under negative pressure.

FAQs

Q1: What is the pore size of the sand core filter?

A1: The sintered glass frit is rated at G3 porosity (15-40um). It supports standard 50mm filter paper and is compatible with 0.22um or 0.45um membrane filters placed on top for fine particle capture.

Q2: Can I use the filter cup with any vacuum pump?

A2: Yes. The standard ground glass joint connects to any laboratory vacuum source capable of reaching 50-100 mbar. The receiving flask collects the filtrate directly, no additional adapter needed.

Q3: How do I clean the sand core after use?

A3: Rinse with appropriate solvent immediately after use. For stubborn residue, soak in chromic acid cleaning solution or aqua regia (handle with care), then rinse thoroughly with deionized water. Autoclaving is possible for sterilization.

Q4: Can the filter head fit multiple flask sizes?

A4: Yes. The LVD-FH-250-500-1000 filter head is designed to fit 250ml, 500ml, and 1000ml receiving flasks via the standard ground glass joint interface, making it a versatile replacement or backup component.
