Needle filter

Product Description

Disposable needle filters have become a fast, convenient, and reliable filtration tool commonly used in laboratories. They have a beautiful and lightweight appearance, high cleanliness, and do not require membrane replacement or filter cleaning, saving complex and time-consuming preparation work. They are widely used in laboratories, including sample pre filtration, clarification and particle removal, liquid and gas sterilization filtration. It is the preferred method for filtering small amounts of HPLC and GC samples, often used in conjunction with disposable syringes. The filtration diameter ranges from 4mm to 50mm, and the processing capacity ranges from 0.5ml to 200ml.

Pioneering the dual insurance production process of double injection molding edge wrapping and ultrasonic welding; The annual export volume is nearly 50 million units, with 90% exported to major economically developed countries around the world. Filters can be provided with OEM services according to customer needs. The consistency between batches of produced filters is good, and there are strict control processes from raw materials to production processes to inbound and outbound shipment management, which greatly ensures the quality and value of the products. Provide commonly used membranes of various specifications: polyethersulfone (PES)/polytetrafluoroethylene (PTFE)/nylon/mixed cellulose (MCE)/glass fiber membrane (GF)/polyvinylidene fluoride (PVDF)/cellulose acetate (CA), etc; The aperture range is from 0.1 μ m to 5 μ m; Diameter 4mm/13mm/17mm/25mm/30mm/47mm, etc;

Product Features

Filter membrane material	main performance
Nylon	Resistant to strong alkali and organic liquids, naturally hydrophilic No need for immersion before use, uniform aperture, good mechanical strength, threaded interface design
Mixed Cellulose (MCE)	High porosity and good interception effect Not resistant to strong acid, strong alkali solutions, and most organic solvents Suitable for filtering aqueous solutions in water machines; Unique threaded interface design
Cellulose acetate (CA)	Natural hydrophilicity Low protein adhesion, suitable for aqueous solution treatment No nitrate. Suitable for filtering groundwater Unified aperture structure; Wide aperture selection; Collection of retained granular cells
Polyether sulfone (PES)	High solvent recovery rate and low residual amount; High altitude physical quantity Extremely high microbial filtration ability; Unique threaded interface design Low protein adsorption, low solubility
Polyvinylidene fluoride (PVDF)	Hydrophobic membrane, non hygroscopic, easy to maintain constant weight Temperature resistant and capable of repeated hot pressing disinfection Chemical corrosion resistance and oxidation resistance; Thread interface design
Polytetrafluoroethylene (PTFE)	Has excellent chemical resistance; Resistant to high temperatures, strong acids, and strong alkalis, with extremely strong hydrophobicity Both hydrophilic and hydrophobic membranes are available to meet different liquid filtration needs
Fiberglass (GF)	Natural hydrophobicity High flux; Large pollutant carrying capacity Good mechanical strength
