K Pure Borosilicate Glass Fiber Pleated Filter Cartridges
K Pure Borosilicate Glass Fiber Pleated Filter Cartridges: High-Efficiency Healthcare Filtration
In critical healthcare and biological processing, the purity of gases and liquids is non-negotiable. K Pure Borosilicate Glass Fiber Pleated Filter Cartridges are engineered to meet these demanding standards, providing a robust barrier against contaminants in sensitive environments.
By utilizing high-surface-area pleated technology combined with advanced borosilicate glass fiber, these cartridges deliver absolute retention and high flow rates, making them an essential component in pharmaceutical and clinical workflows
Key Applications in Healthcare
The K Pure Glass Fiber Pleated Filter Cartridges series is specifically designed for versatility across both gas and liquid phases:
- Gas & Vent Filtration: Protecting sterile tanks and bioreactors from airborne contaminants and ensuring sterile air supply.
- Biological Liquid Processing: Pre-filtration of serums, cell culture media, and high-viscosity biological fluids.
- Bioburden Reduction: Significantly lowering microbial loads to protect downstream sterile filters and sensitive equipment.
- Demanding Pre-filtration: Removing rigid and deformable particulates that could compromise final product quality.

Why Choose Borosilicate Glass Fiber Pleated Filter Cartridges?
Unlike standard synthetic fibers, borosilicate glass fiber offers unique advantages for healthcare applications:
- High Dirt-Holding Capacity: The complex matrix of the glass fibers allows for depth filtration, trapping more contaminants before the pressure drop increases.
- Thermal Stability: Capable of withstanding rigorous sterilization cycles, including autoclaving and in-line steam sterilization.
- Low Extractables: Ensures that the filter media itself does not leach impurities into the filtered product, maintaining biological integrity.

Frequently Asked Questions (FAQ)
1. What does “Absolute Retention” mean for the K Pure series?
Absolute retention (ranging from 1 μm to 25 μm) means that the filter is rated to remove 99.9% (Beta 1000) of particles at that specific micron size, providing a reliable safety margin compared to “nominal” rated filters.
2. Can these cartridges be used for both air and liquid?
Yes. While they excel in gas and vent filtration due to the natural properties of glass fiber, they are equally effective in biological liquid processing where high dirt-holding capacity and bioburden reduction are required.
3. How does the pleated design improve performance?
The pleated geometry significantly increases the effective filtration area within the same cartridge footprint. This results in lower initial pressure drops, higher flow rates, and a longer service life before a change-out is needed.
4. Are K Pure cartridges compatible with steam sterilization?
Yes, our borosilicate glass fiber cartridges are designed to endure the high temperatures associated with standard healthcare sterilization protocols without compromising the structural integrity of the pleats or the media.
4. Why is borosilicate glass fiber preferred over polypropylene for pre-filtration?
Borosilicate glass fiber generally offers superior temperature resistance and better performance with fine, sub-micron particulates and oils, making it the “gold standard” for demanding healthcare pre-filtration.
