Cellulose nitrate-cellulose acetate (CN-CA) filter membrane

The membrane has good porosity and hydrophilicity, cost performance is high. The membrane can be used at a wide range of temperatures, it can withstand dilute acid (not applicable to ketones, esters, strong acids and alkalis and other liquid filtration). In the microbial detection method, the nutrition penetration between the membrane and the culture medium is good, the growth state of colonies is relatively better, there is no obvious diffusion in the growth of colonies.

Specification

Features

• Most suitable for microbial interception and growth, with a microbial resurrection rate greater than 90%
• The membrane is equipped with grid lines, which facilitate the resolution and counting of colonies without affecting their growth;
• Single piece sterile packaging, direct use, saves sterilization time and avoids secondary pollution during operation;
• The combination of different colored membranes and grid lines is suitable for different microbial detection. White background and black grid 0.22 μ m. detecting bacteria and Escherichia coli in water, mainly used for counting Escherichia coli and bacterial colonies; Black background and white grid 0.22 μ m mainly used for counting and detecting the total number of molds and yeast
