Characteristics and Applications of MCE Grid Membrane Filter

Hawach Scientific provides high-quality MCE Grid membrane filter and the products have been exported to more than 120 countries and areas.

Characteristics of MCE Grid Membrane Filters:

MCE Grid membrane filter is a kind of mixed cellulose wafer film with mesh, which is mainly used to count the bacterial colony after culture, and it can be divided into two specifications: black background and white background. We can offer both continuous packing and independent packing diameters 47mm/50mm, pore size 0.22 um/0.45 um/0.8 um. Mainly used for environmental monitoring, microbial count, detection, and bacterial detection, in beer, food, juice, milk, pharmaceutical and other areas of microbial testing achieved consistent praise.

The product features are most suitable for microbial interception and growth, and the microbial resurrection rate is 90%. The membrane has a grid line, which is easy to distinguish and count the colony and does not affect colony growth.

Single-piece aseptic packaging, direct use, save sterilization time, and avoids secondary pollution in the operation; The combination of the diaphragm and grid lines with different colors is suitable for different microbial detection.

White background with black grid 0.45 um, detection of water bacteria, coliform bacteria, mainly used for e. Coli and bacterial colony count; Black background with white grid 0.45 um, mainly used for mold and yeast count detection.

Material Composition: MCE grid membrane filters are made from a mixture of cellulose acetate and cellulose nitrate. This composition provides a balance of hydrophilic and hydrophobic properties.

Pore Structure: MCE filters have a uniform and consistent pore structure. They are available in a range of pore sizes, typically from 0.2 micrometers to several micrometers, depending on the application.

Grid Pattern: The distinguishing feature of MCE grid membrane filters is the presence of a grid pattern printed onto the membrane surface. This grid helps with sample positioning and counting during analysis.

Hydrophilicity: MCE filters are generally hydrophilic, which means they have an affinity for water and aqueous solutions. This makes them suitable for applications involving water-based samples.

Low Protein Binding: MCE filters have low protein-binding characteristics, making them suitable for protein and enzyme filtration without significant adsorption.

Chemical Compatibility: They are compatible with a wide range of chemicals, including acids, bases, and some organic solvents. However, compatibility may vary depending on specific products and applications.

Applications of MCE Grid Membrane Filters:

Product USES aseptic filtration, air detection, particle detection, particle removal of ionized water microbiological analysis particle detection, particle removal, dairy microbiological, yeast, mold detection. Fluid quality analysis, particle collection, and analysis for use.

Microbiological Analysis: MCE grid membrane filters are commonly used in microbiology laboratories for microbial enumeration, such as total and fecal coliform testing, yeast and mold counting, and other microbial analysis procedures.

Air Quality Monitoring: They are used in air monitoring equipment to trap airborne particles for subsequent analysis, particularly in environmental monitoring and cleanroom testing.

Particle Counting: MCE grid membrane filters are employed in particle counters to quantify and size particles in liquids, air, and other samples.

Food and Beverage Analysis: MCE filters are used in the food and beverage industry for the filtration of liquid samples, particularly to analyze microbiological contaminants.

Quality Control: They are used in various quality control and assurance processes to test the microbial quality of products and raw materials.

Sample Filtration: MCE grid membrane filters can be used for general laboratory sample filtration when a uniform pore structure and grid pattern are advantageous for positioning and identification.

Liquid Scintillation: In liquid scintillation counting, MCE filters are used to capture liquid scintillation cocktails and retain radioactive particles for radiation measurement.

Environmental Monitoring: MCE grid membrane filters are used for the analysis of environmental samples, including water, soil, and sediment, to capture and quantify particles and contaminants.
