BIOLOGIX Lab Bottletop Filters CA PES Membrane Sterile

Description

Product Overview

The BIOLOGIX bottletop filtration system is designed for high-performance liquid filtration in laboratory and industrial settings. It features ultra-fine CA (cellulose acetate) or PES (polyethersulfone) membranes that provide exceptional microbial retention and high throughput, making it suitable for contamination-sensitive applications. Each unit is gamma-ray sterilized, ensuring they are sterile, non-pyrogenic, and free from DNase/RNase. The system includes a graduated funnel with a capacity of 250ml to 1000ml and a GL45 glass adapter for compatibility with standard lab glassware. Package dimensions are 13.43 x 8.82 x 4.96 inches, and it weighs 6.74 ounces, with availability in 1-piece or 12-piece sizes.

Usage

This filtration system is ideal for laboratories and industrial facilities requiring sterile liquid processing. It is commonly used in cell culture media sterilization, clarification of protein and buffer solutions, and removal of particulates from oils and other fluids. The target audience includes research scientists, lab technicians, and industrial operators in biotechnology, pharmaceuticals, and chemical processing. Its ergonomic design and sterile readiness make it suitable for environments where contamination control and efficiency are critical.

FAQ

What is the difference between CA and PES membranes?

CA membranes are cellulose acetate-based and offer high protein binding resistance, making them ideal for biological solutions. PES membranes are polyethersulfone and provide faster flow rates and higher chemical compatibility, suitable for aggressive solvents and buffers.

Are these filters reusable?

No, these are disposable, single-use filters designed for sterility and convenience. Reuse could compromise filtration integrity and lead to contamination.

What vacuum pressure is recommended for use?

They are optimized for standard laboratory vacuum systems, typically operating at pressures up to 15 inches of mercury for efficient filtration without damaging the membrane.

Can I use these filters with non-standard glassware?

The GL45 adapter is designed for compatibility with most common lab glassware. For non-standard setups, check the thread size or consult the manufacturer to ensure proper fit.

How should I store the filters before use?

Store in a cool, dry place away from direct sunlight. The sterile packaging should remain sealed until use to maintain integrity and prevent contamination.
