Consider the many healthcare applications where a vent filter would be required, such as in IV devices, ostomy bags, or diagnostic assays, to name a few. Understand there are numerous benefits of using filtration membranes and devices specifically designed for healthcare applications to ensure a safe clinical environment.
Products used in medical applications must, by design, protect both patients and medical professionals against contamination that may arise from various sources. For example, many diseases spread through airborne pathways when microorganisms carried by droplets from respiratory secretions come in direct contact with the mucous membranes of the eyes, nose, or mouth of another person. Filtration of air and service gases as well as in venting of medical equipment, play a key role in trapping airborne contaminants which may place the health of an individual at risk.
Microporous hydrophobic membranes block liquids and aerosols while allowing air to flow through the membrane. They also reduce the possibility of bacterial and viral complications while aiding in the healing process. Optimized membrane solutions facilitate a quicker recovery while reducing hospitalization times and overall healthcare costs.
There are several mechanisms by which a filtration membrane achieves these goals. Particles may be arrested by the sieve retention mechanism when trapped in pores that are smaller than the particles themselves. Direct Interception is when gravitation settings and electrical attraction forces are both involved in an adsorptive capture. Other mechanisms are related to inertial and diffusional interception, which are heightened in gas and air streams because of the lower viscosities that pose little impediment to the trajectory of an airborne particle.
It is critical in the process of selecting a filter membrane the following aspects be considered: particle filtration efficiency, air flow rates to ensure proper pressure drop across the membrane surface, and water intrusion pressure rating. Additional concerns could be wetting, chemical and thermal resistance, compatibility with the selected sterilization method, and compliance with relevant guidelines.
Exhibiting robust handling due to being cast on a non-woven support and its surface modified with a proprietary hydrophobic process, Versapor® RC membranes meet the above criteria. These products are used where particle, bacterial, and viral retention are required in medical venting applications and are one of our most durable products – You will see the Versapor® RC membrane being used in such applications as patient’s IV set vent, urinary catherization, pharmaceutical re-constitution, and negative pressure dressings to name a few.
The Versapor® RC membrane portfolio utilizes three materials of construction:
- Acrylic Copolymer Matrix: Available in multiple pore sizes, its microporous structure is designed to ensure particulate retention, while maintaining high flow rates. It also offers dimensional strength, and broad chemical compatibility.
- Non-woven nylon support: The support fabric is manufactured using continuous nylon fibers randomly arranged, which enhance the physical properties of the membrane by conferring high tensile strength and dimensional stability.
- Proprietary Post-Treatment: This environmentally friendly process involves the application of a fluoropolymer surface modification to the membrane matrix, which imparts wetting resistance against low surface tension fluids.
We offer a different variety of pore-size ratings for the Versapor® RC
Versapor® RC membranes are compatible with standard methods of sealing, such as:
- Radio Frequency (RF) welding
This product family is also compatible with common sterilization methods, such as gamma radiation, ethylene oxide (EtO), and autoclave. Moreover, bacterial and viral filtration efficiency testing results indicate that these can serve as effective barriers in reducing the risk of airborne contamination in venting applications under the applied test conditions.
Biocompatibility testing results demonstrate that this material meets the requirements of the USP Biological Reactivity Testing <88> (USP Class VI Plastics Tests).
Versapor® RC membrane grades have been designed to meet the requirements of Regulation 2017/1000. For additional details on this and other regulations, please visit the ‘Quality at Pall” webpage. By visiting this site, users have immediate access to the most up to date information from Pall on these topics.
Versapor® RC membranes are manufactured in accordance with current Good Manufacturing Practices (cGMP). The Pall facility where these membranes are manufactured operates and is certified to the Quality and Environmental Management Systems current revisions of ISO-9001 and ISO-14001.
