what are sintered glass filter | Lvyuan Guide
Sintered glass filters provide superior chemical resistance, temperature tolerance, and precise pore size control, making them ideal for various demanding applications across industries. Their durability and cleanability contribute to cost-effectiveness and long-term use.
What are Sintered Glass Filters?
Sintered glass filters offer a robust and versatile solution for filtration applications where high chemical resistance, temperature tolerance, and precise pore size control are crucial. This article clarifies their properties and applications, addressing common questions professionals face when selecting the right filtration media.
Understanding the Sintering Process
Sintered glass filters are created by heating a mixture of finely ground glass particles to a temperature just below their melting point. This process, called sintering, fuses the particles together, creating a rigid porous structure. The resulting filter exhibits a uniform pore size distribution, determined by the particle size of the initial glass powder. This precise control over porosity is a key advantage of sintered glass filters.
Advantages of Sintered Glass Filters
* High Chemical Resistance: Sintered glass filters are highly resistant to a wide range of chemicals, making them suitable for aggressive media. This inertness prevents leaching of filter components into the filtrate, ensuring sample purity.
* Excellent Temperature Resistance: They can withstand high temperatures and thermal shock, extending their usability in demanding applications.
* Precise Pore Size Control: The consistent pore structure allows for precise control over particle removal, enabling effective separation of solids from liquids or gases.
* Cleanability and Sterilizability: Sintered glass filters are easily cleaned and sterilized, facilitating reuse and maintaining hygiene standards.
* Long Service Life: Their durability contributes to a longer lifespan compared to some other filter types.
Applications of Sintered Glass Filters
Sintered glass filters find applications across numerous industries, including:
* Pharmaceutical and Biotechnology: Sterile filtration, clarification of pharmaceutical solutions.
* Chemical Processing: Filtration of corrosive liquids and gases.
* Environmental Monitoring: Water purification, air sampling.
* Analytical Chemistry: Sample preparation, separation of particulates.
Choosing the Right Sintered Glass Filter
Selecting the appropriate sintered glass filter involves considering factors such as the required pore size, chemical compatibility, operating temperature, and the volume of fluid to be filtered. The desired level of filtration accuracy also plays a crucial role in the selection process.

Porous Plastic Filter
How to Calculate Filter Porosity?
Filter porosity is classified into three major types: Primary Porosity, Secondary Porosity, and Effective Porosity. The calculation involves determining the ratio of the volume of gaps in the filter to the total volume, expressed as a percentage.
Porosity = (Volume of Empty Gaps/Total Volume of Filter) x 100
Other methods include:
• Direct Methods: Calculate the entire volume of the porous filter and the volume of a skeletal filter (without pores) to find the porosity.
• Computed Methods: Use modern computer technology to obtain a 3D image of a porous filter and employ defect analysis techniques.
• Water Evaporation Technique: Calculate porosity by determining the difference in weight between the saturated filter in water and the dried filter.
