PES (Polyethersulfone) Needle Filter
PES (polyethersulfone) needle filters are widely used in laboratory filtration applications for media, culture solutions, serum solutions, growth hormones, nutrient solutions, and other special-purpose solutions that require particular handling.
CA (Cellulose Acetate) Needle Filter
CA (cellulose acetate) needle filters are suitable for filtering aqueous solutions. Cellulose acetate membranes feature high flow rates, thermal stability, and low adsorption.
PP (Polypropylene) Needle Filter
PP (polypropylene) needle filters are naturally hydrophobic filtration media characterized by high throughput and high dirt-holding capacity, making them suitable for routine filtration of organic solvents with relatively high particle content.
MCE (Mixed Cellulose) Needle Filter
The MCE mixed-cellulose ester syringe filter is naturally hydrophilic and is used for filtering aqueous solvents, removing particulates, and performing biochemical analyses (protein retention). It is suitable for preparing HPLC samples and filtering solvents.
RC (Regenerated Cellulose) Needle Filter
RC (regenerated cellulose) is made from natural cellulose through a series of chemical and physical processes to form a film. RC films exhibit excellent hydrophilicity and strong chemical stability.
PVDF (Polyvinylidene Fluoride) Needle Filter
PVDF (polyvinylidene fluoride) membranes exhibit lower protein binding rates compared to cellulose nitrate and polytetrafluoroethylene filters. They possess excellent chemical compatibility, are compatible with a wide range of organic solvents, and offer broad applicability. Additionally, they demonstrate good resistance to oxidation and heat, making them suitable for sample preparation and solvent filtration in applications such as HPLC and GC.
