Filtration Mechanism
The filtration process is based on a membrane separation structure. When a liquid sample passes through the filter under syringe pressure, unwanted particles are retained on the membrane surface while the filtered liquid flows through the outlet.
The filtration performance depends on several factors:
Different pore size options allow users to select suitable filtration precision for analytical and laboratory processes.
Product Structure Design
The product consists of a filter housing, membrane layer, support structure, and connection ports. Each component is designed to maintain stable liquid flow and reduce sample loss during filtration.
Key structural features include:
The housing material can be selected according to chemical resistance requirements and application conditions.
Membrane Material Options
Hangzhou Hanzhikang Purification Equipment Co., Ltd. offers different membrane choices to match different sample types.
PES Membrane
Suitable for aqueous solutions and biological sample preparation. It provides low protein binding characteristics for specific laboratory applications.
PTFE Membrane
