Globe Scientific Bottle Top Filters PES Membrane Lab

Description

Product Overview

Globe Scientific bottle top filters are precision-engineered filtration devices designed for laboratory applications requiring clarification, separation, or sterilization of aqueous solutions. These filters incorporate high-performance Polyether Sulfone (PES) membranes, available in 0.10μm, 0.22μm, and 0.45μm porosities to accommodate various filtration needs. Constructed from virgin USP Class VI polystyrene (PS) and acrylonitrile butadiene styrene (ABS), they offer exceptional chemical resistance and durability. The filters are clearly marked with porosity specifications for easy identification and selection. With package dimensions of 21.5 x 17 x 14 inches and a weight of 10.1 pounds, each unit is designed for stable benchtop use and seamless integration into laboratory workflows.

Usage

These bottle top filters are ideal for handling cell culture media, biologic solutions, and other aqueous substances in research, pharmaceutical, and biotech laboratories. They are commonly used in sterile filtration processes, sample preparation, and solution clarification where maintaining purity and preventing contamination are critical. The filters are compatible with Diamond PureFlow solution bottles and any laboratory media bottles featuring GL45 threads, making them versatile across different equipment setups. Target users include laboratory technicians, researchers, and quality control professionals working in environments that demand reliable, efficient filtration performance.
