Water phase needle filterIt is a micro filtration device based on microfluidic technology, mainly used for purification and pretreatment of aqueous solutions, playing a key role in laboratories and industrial fields.

　　Water phase needle filterThe working principle of the filter is based on physical filtration and microfluidic technology, with high filtration accuracy. The pore size of the filter membrane can range from a few micrometers to a few nanometers, which can effectively remove suspended solids, colloids, bacteria, viruses, etc. from water. Simultaneously easy to operate, usually disposable, without the need for membrane replacement or cleaning.

Application fields:

Laboratory applications:

Sample pretreatment: In high-performance liquid chromatography (HPLC) and gas chromatography (GC) analysis, filtering the sample can remove particulate matter, prevent column blockage, and extend equipment life.

Solution purification: In organic chemical synthesis, filtering the reaction mixture can remove unreacted catalysts, solvent impurities, etc., and obtain pure target products.

Microbial testing: Used for sterile filtration of samples in beverage and dairy product testing to prevent microbial contamination of the testing system.

Industrial applications:

Microelectronics industry: filters high-purity chemicals such as photoresist and developer solution, removes particles and impurities, and prevents contamination of sensitive electronic components.

Pharmaceutical industry: In the preparation of antibiotic solutions, bacteria and particles are removed to ensure the sterility and quality of the final product.

Environmental monitoring: used for water quality analysis, wastewater and exhaust gas analysis, providing accurate environmental data.
