"Definitely worth a look if you are inclined towards such tremendous pixel-art cuteness."
Filters are often categorized by their membrane material, which determines their chemical compatibility. Common options found in professional laboratory catalogs include:
: Specialized use of hydrophobic PTFE filters (1.0–5.0 ) for gas exchange in grain spawn and liquid culture jars. Purchasing Options
: Provides sterile 13mm PES filters in 50-count cases for roughly $52 . sp furo 13wmv
: Naturally hydrophobic and highly resistant to aggressive organic solvents, acids, and bases. It is the "gold standard" for GC and HPLC sample preparation.
: Offers 100-packs of 13mm PTFE filters for approximately $27 . Filters are often categorized by their membrane material,
The following guide explores the specifications and applications of high-performance 13mm syringe filters, often characterized by similar nomenclature in laboratory procurement systems. Understanding the 13mm Syringe Filter
: Secure threaded interfaces that prevent the filter from popping off under pressure. Pore Size : Usually for sterile filtration or for general clarification. : Naturally hydrophobic and highly resistant to aggressive
Syringe filters are used to remove particulate matter from liquid samples before analysis, such as High-Performance Liquid Chromatography (HPLC) or Gas Chromatography (GC). A "13mm" designation refers to the housing diameter, which is ideal for filtering small sample volumes (typically 1–10 mL) while minimizing sample loss (holdup volume). Key Specifications & Membrane Types
: Known for high flow rates and low protein binding, making it suitable for biological and pharmaceutical solutions.
: Sterilizing small volumes of culture media or protein solutions using PES membranes.
