Whatman 9915-2502 Uniflo Syringe Filters 25mm 0.2 PES 200/PK

These syringe filters are designed for filtering small sample volumes up to about 100 mL, making them suitable for HPLC sample preparation, biological solutions, buffers, and general laboratory filtration. The PES membrane provides clean filtrate while minimizing sample loss.

The 9915-2502 uses a polyethersulfone (PES) membrane with a polypropylene housing. PES membranes are chemically resistant, handle elevated temperatures, and provide low protein binding, making them ideal for biological and aqueous samples.

This model features a 0.2 µm pore size and 25 mm diameter, which helps remove fine particulates and microorganisms while maintaining good flow rates for laboratory sample preparation.

Yes. The 9915-2502 version is supplied sterile and ready for use, which helps reduce contamination risk during filtration of sensitive biological or analytical samples.

The filter includes a female Luer-lock inlet and male slip-Luer outlet, allowing compatibility with standard laboratory syringes and easy integration into common filtration workflows.
