The 250 mL Bottle Top Vacuum Filter with a 0.45 μm PVDF (Polyvinylidene Fluoride) membrane is ideal for fast, sterile filtration of buffers, culture media, and aqueous solutions in laboratory environments. The PVDF membrane is highly resistant to chemicals, features low extractables, and exhibits low protein binding—ensuring high sample recovery and purity.
Designed for convenience and performance, this unit includes a clear, durable housing with precise graduation marks for accurate volume measurement. The universal hose connector supports a variety of tubing sizes for easy integration into standard vacuum filtration setups.
Each unit is gamma-ray sterilized and individually packaged, and certified endotoxin- and pyrogen-free—making it suitable for sterile and contamination-sensitive applications in research, pharmaceutical, and clinical settings.
