Diameter (mm) 50/90

Volume (mL) 250/500/1000

Pore Size (μm) 0.1/0.22/0.45/1.0/3.0/5.0, etc.

Application

Sterilization or clarification of large volumes of biological liquids in the laboratory, typically processing 150mL to 2L; clarification of cell culture media; can be used to remove mycoplasma from liquids.

Features

Single-use, pre-sterilized by gamma irradiation; sterilization filtration efficiency (0.22μm): LRV > 7 for Brevundimonas diminuta, ATCC19146, ASTM bacterial challenge test; non-pyrogenic, surfactant-free, extremely low extractables; extremely low protein adsorption rate <1.5% (PES); ultra-high flow rate and flux, enabling faster and greater liquid filtration; GL45 interface compatible with standard laboratory receiving containers; ergonomic design with graduated markings on both upper and lower containers, making filtration more convenient and easy to operate.

Product Features

· Single-use sterile design: The filtration bottle and membrane are sterilized by gamma irradiation before leaving the factory, ready to use out of the bag, avoiding cross-contamination, eliminating the cleaning and high-temperature sterilization processes required for traditional glass filters, and preventing experimental errors caused by reagent residues or biological contamination.

· Easy operation: Pre-assembled unit with the filter membrane already installed; users only need to pour in the liquid and connect to a vacuum pump to begin filtration, without complex installation or debugging.

· Diverse membrane options: Available in various materials and pore sizes to meet different filtration needs, such as cell culture media filtration, organic solvent filtration, and sterilization filtration.

· Flexible adaptation to various scenarios: Multiple capacity specifications are available, ranging from 50mL small volumes to 5L large capacities, suitable for various experimental scenarios including microbial detection, culture media preparation, and HPLC liquid chromatography analysis.

· Lightweight yet sturdy: Light in weight with a robust outer wall structure, facilitating handling and transportation.
