With a pore size of 0.22 m and a membrane diameter of 33 mm, our syringe filter features smaller and more uniform pores, enabling it to tiny particles, ensuring superior filtration quality efficiently Utilizing a hydrophilic PES membrane, this filter offers a high flow rate and rapid wetting without pre-wetting, along with low protein adsorption. It is ideal for various liquid filtration, including culture media, reagents, and pharmaceutical solutions The syringe filter features a unique threaded interface that fits both luer slip and luer lock syringes, providing a secure and leak-free connection for reliable filtration Each pack contains 50 syringe filters. Each filter is individually packaged, allowing for direct use and avoiding the need for additional steps, providing great convenience this syringe filter is widely used in laboratory-style research, HPLC, and analysis for sample solution filtration, filtration of pharmaceutical solutions, and water sample Color: As shown Material: Plastic Package Contents: 1set x Sterile PES Filter Only the above package content, other products are not included.
