BIOLOGIX Bottletop Lab Filter Sterile PES Membrane

Description

Product Overview

The BIOLOGIX Bottletop Lab Filter is a premium filtration system designed for laboratory and industrial applications requiring sterile, high-throughput liquid processing. Constructed with lab-grade PES (Polyethersulfone) membranes available in 0.22μm and 0.45μm pore sizes, these filters provide exceptional microbial retention and particle removal. The units are gamma-ray sterilized, ensuring they are non-pyrogenic and free from DNase/RNase contamination. Each filter features an ergonomic graduated funnel with capacity markings from 250ml to 1000ml, coupled with a standard GL45 glass adapter for secure attachment to laboratory glassware. The integrated filter housing minimizes particle exposure, while the angled vacuum pipe design prevents hose tangling during operation. Available in both single-unit and 12-piece packaging options, these disposable filters maintain consistent performance across various fluid types.

Usage

This filtration system is engineered for environments where contamination control and efficiency are critical. In laboratory settings, it is ideal for sterilizing cell culture media, clarifying protein solutions, and filtering buffer preparations in biological research, pharmaceutical development, and clinical diagnostics. The industrial applications include removing particulates from oils, solvents, and other process fluids in manufacturing and quality control operations. Target users include research scientists, lab technicians, and industrial process engineers who require reliable, sterile filtration with minimal setup time. The ready-to-use design makes it suitable for both routine procedures and time-sensitive experiments where maintaining sample integrity is paramount.

Why Choose Us

BIOLOGIX bottle top filters stand out through their combination of superior materials and thoughtful design. The ultra-fine PES membrane offers higher flow rates and better chemical compatibility compared to traditional filters, reducing processing time without compromising sterility. Each unit undergoes rigorous gamma-ray sterilization and quality checks to ensure they meet strict laboratory standards for being non-pyrogenic and free from enzymatic contaminants. The ergonomic features, such as the graduated funnel and angled vacuum connection, enhance usability and reduce the risk of operational errors. This attention to detail results in a product that delivers consistent, reliable performance, making it a trusted choice for professionals who cannot afford filtration failures.

FAQ

What applications are these filters suitable for?

These filters are designed for both laboratory and industrial use, including sterilizing cell culture media, clarifying protein and buffer solutions, and removing particulates from oils and solvents in various fluid processing applications.

Are the filters truly sterile and ready to use?

Yes, each unit is gamma-ray sterilized and packaged to maintain sterility. They are non-pyrogenic, DNase/RNase-free, and can be used directly upon opening without additional preparation.

What glassware sizes does the GL45 adapter fit?

The GL45 adapter is compatible with standard laboratory glassware that uses GL45 threads, which is common for bottles and flasks in the 250ml to 1000ml capacity range.

How do I choose between 0.22μm and 0.45μm pore sizes?

The 0.22μm pore size is typically used for sterile filtration to remove bacteria and smaller microorganisms, while the 0.45μm size is ideal for clarifying solutions and removing larger particles where sterility is less critical.

Can these filters be used with aggressive chemicals?

The PES membrane offers good chemical compatibility with many aqueous solutions and mild solvents, but for highly aggressive chemicals, it is recommended to verify compatibility based on the specific chemical properties.
