Introduction to PVDF Filters

PVDF lab pleated filters are crafted from polyvinylidene fluoride, a highly non-reactive and pure thermoplastic fluoropolymer. These filters are renowned for their capability to withstand harsh chemicals, high temperatures up to 150°C, and maintain structural integrity under high pressure and dynamic conditions.

Mechanism of Filtration

The pleated design of PVDF filters increases the surface area, which enhances the dirt-holding capacity and extends the lifespan. The filtration mechanism primarily involves size exclusion and adsorption. The filtration efficiency can range from 0.1 to 1.0 microns, making it suitable for removing particulates and microbes in the laboratory setting.

Numerical Analysis:

• Average pore size: 0.2 microns
• Filtration efficiency: >99.9% for particulates ≥ 0.3 microns
• Flow rate: 10 - 30 liters per minute at 1-bar pressure

Applications in Laboratory and Industry

PVDF lab pleated filters are utilized in various applications:

• Microbial filtration of pharmaceutical products, ensuring compliance with stringent regulatory standards.
• Clarification of chemical solutions and solvents used in research laboratories.
• Water purification systems requiring high chemical resistance and thermal stability.
• Filtration of gases in industrial settings, to prevent contamination and ensure environmental safety.

Benefits of Using PVDF Filters

The advantages of employing PVDF lab pleated filters include:

• High chemical resistance, suitable for corrosive substances and a broad pH range.
• Superior mechanical strength, supporting high flow rates and pressures.
• Thermal stability, allowing usage in high-temperature applications.
• Long lifespan, reducing frequency of replacement and operational costs.
