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;
