Pre-Sterilized GCN Membrane in Reel Form Type- RGCN

Pre-Sterilized GCN Membrane in Reel Form Type RGCN is an advanced filtration solution designed for high-volume microbiological testing and continuous monitoring applications. These membranes come in a reel (roll) format with grid marking, allowing efficient processing of multiple samples with improved accuracy in colony counting.

Widely used in international laboratories across the USA, UK, Germany, and Australia, these membranes are known for their sterility, consistency, and ease of use in automated or repetitive testing processes.

What is Pre-Sterilized GCN Membrane in Reel Form Type RGCN?

RGCN membranes are grid marked cellulose nitrate membranes supplied in reel form, pre-sterilized using ethylene oxide (EO). This format allows users to cut the required size as needed, making it highly suitable for continuous or bulk microbiological testing.

The grid marking on the membrane ensures easy visualization and accurate counting of microbial colonies, while the sterile packaging guarantees contamination-free operation.

Where Are These Membranes Used?

These membranes are widely used in:

• High-Volume Microbiology Testing: Ideal for repetitive and bulk sample analysis
• Water Quality Testing: Continuous monitoring of microbial contamination
• Food & Beverage Industry: Ensures hygiene and safety standards
• Pharmaceutical Testing: Used in sterility and microbial analysis
• Environmental Monitoring: For air and water microbial testing

They are especially useful in applications where large-scale and continuous testing is required.

Why Are Reel Form Membranes Used?

Reel form membranes are preferred because they offer flexibility, efficiency, and cost-effectiveness.

Key reasons include:

• Continuous roll format for bulk usage
• Pre-sterilized (EO sterile) for immediate use
• Grid marking for easy colony counting
• Reduces handling time and waste
• Ideal for automated or repetitive processes

They help laboratories improve productivity and accuracy.

Material and Construction

These membranes are made from Cellulose Nitrate (CN) with grid marking, offering:

• Hydrophilic surface for aqueous filtration
• Strong microbial retention
• Clear grid pattern for colony counting
• Uniform pore structure

Typical Specifications:

• Pore Sizes: 0.2µm, 0.45µm
• Format: Reel (roll form)
• Sterility: EO pre-sterilized

Working Principle

RGCN membranes work on a mechanical filtration process:

• Liquid passes through the membrane
• Microorganisms are retained on the surface
• Grid marking helps in counting colonies after incubation

The reel format allows continuous use, making it ideal for large-scale microbial testing operations.
