The hollow fibers produced by our company mainly include the following types:
Hollow Fiber Membrane
Hollow fiber membrane is an ultra-fine, straw-like tube that acts as a physical filter to separate particles and molecules from liquids or gases.
Hollow Fiber Filter
Hollow fiber filter is a highly efficient filtration device consisting of a bundle of thousands of tiny, straw-like semi-permeable tubes.
Advantages of Hollow Fiber
Increased Surface Area
The tubular structure of hollow fiber translates to a significantly increased surface area. This characteristic enhances the contact between the medium and the cells, leading to higher productivity and improved yields.
Enhanced Mass Transfer
Efficient mass transfer is a critical factor in biopharmaceutical production. Hollow fiber technology excels in this aspect, facilitating rapid exchange of nutrients and metabolites, ultimately maximizing the efficiency of the production process.
Cost-Effective Solutions
Beyond its technical advantages, hollow fiber technology offers cost-effective solutions for biopharmaceutical companies. The streamlined processes and increased productivity contribute to a more economically viable production model.
Applications of Hollow Fiber
Protein concentration and purification
One of the most common applications of hollow fiber filters is in protein concentration, purification, and diafiltration. Their high surface area and low protein-binding PES material make them ideal for handling delicate biological molecules.
Cell harvest and clarification
In bioprocessing, hollow fiber filters are widely used for clarifying cell cultures and recovering microbial or mammalian cells. The outside-in or inside-out filtration modes allow flexibility in processing fermentation broths, cell suspensions, or other complex mixtures.
Virus and vaccine processing
Another critical use of hollow fiber filters is in virus concentration and vaccine manufacturing. Hollow fibers can separate viruses, virus-like particles (VLPs), or extracellular vesicles (EVs) while maintaining structural integrity.
Nanomaterials and particle fractionation
Beyond life sciences, hollow fiber filters are used in processing nanomaterials and suspensions. They can fractionate particles by size, concentrate colloids, and purify nano-formulations.

Storage Precautions for Hollow Fibers
The new mbr membrane should be stored indoors and in a cool and dry place without direct sunlight. The indoor temperature range should be at -0°℃~45℃.
The MBR membrane stored in 1% SMBS standard protective solution will freeze below -4°c, so the temperature should not be too low.
If it is not used for the time being, we should keep the components in the original packaging as much as possible. Generally speaking, if the indoor temperature is not lower than 45 C, it is necessary to check the growth of microorganisms inside the membrane element every 3 months. If the protective solution is cloudy, remove the packaging bag, re-immerse the MBR membrane element in the protective solution, take out after 1 hour, drain it, and then re-seal it.
If there is no equipment for storage, the new hollow fiber MBR membrane element can be stored in the original protective liquid bag for up to 12 months. We should clean it before into used.
The pH value of the mbr hollow fiber membrane preservation solution should be greater than 3. The pH value will decrease when sodium hydrogen sulfite is oxidized to sulfuric acid.
