Sartorius Filter Paper, Cellulose Nitrate Filter 0.45um 47mm Dia Filter Paper, Made in Germany. It is Ideal for research and analytical laboratory use.

Sterile, individually packaged filters with effective retention, high flow rate, and optimum colony growth. The printed grid divides the filtration area into 130 squares, each measuring 3.1 x 3.1 mm. This is Sartorius Brand Germany Vacuum Membrane Filter paper (0.45 μm, Dia: 47mm), which is primarily used in analytical laboratories and research centers. Cellulose nitrate filters are commonly used in various scientific and industrial applications, particularly in filtration processes. These filters are made from cellulose nitrate, a polymer derived from cellulose, which is treated with nitric acid. Here are some key points about cellulose nitrate filters:

Properties of Sartorius Filter Paper, Cellulose Nitrate Filter

• Pore Size: Available in various pore sizes, allowing for the filtration of different particle sizes.
• Chemical Compatibility: They are generally compatible with a range of solvents and solutions, though specific compatibility should always be verified.
• Thermal Stability: Cellulose nitrate can degrade at high temperatures, so these filters are not suitable for high-temperature applications.

Applications of Sartorius Filter Paper, Cellulose Nitrate Filter

• Microbiology: Used for microbiological analysis, such as the filtration of bacteria and other microorganisms from samples.
• Pharmaceuticals: Employed in the filtration of solutions during drug production to ensure sterility.
• Environmental Testing: Useful for filtering water and soil samples to remove particulate matter for analysis.
• Laboratory Research: Commonly used in various laboratory experiments requiring precise filtration.

Advantages

• Efficiency: High filtration efficiency for small particles.
• Cost-Effectiveness: Generally more affordable compared to some other filter materials.
• Ease of Use: Simple to handle and use in laboratory settings.

Limitations

• Chemical Resistance: Not resistant to strong acids or bases; can be damaged by certain organic solvents.
• Limited Reusability: Typically single-use or limited reusability, depending on the application.

Handling and Disposal

• Proper handling is crucial to avoid contamination.
• Disposal should comply with local regulations, especially if used with hazardous materials.
