OEM Devices
OEM Filter devices are needed for new developing technology that pushes the limit of patent care. New medical devices are being developed to meet the unique needs of new medical developments and filtration is often key to success of those procedures. Filtration products have to be designed to meet the needs of the OEM tool and protect the patent and tool for future use. Filters have to be designed to meet the application, tested to work properly, validated to meet requirements, and 100% tested so they word every time when installed in to a medical device.

Vacuum/Vent Filtration
Vacuum or vent filters allow for the protection of people and equipment. For vacuum filters they filter the air from locations that have potential pollutants that could cause damage and/or contaminate the vacuum pump rendering it as a source of contamination for future use. Vent filters allow protection from incoming or outgoing air to protect the process fluid in tanks or containers from outside contamination. The filters acts ask a barriers to protect the sterility of the process fluids and equipment. It is critical in medical applications to keep separation but allow air to flow.

Disc/Syringe Filtration
Media disc filters or syringe filters are utilized for testing of small volumes of filtered materials. They can be used to test material to figure out the best filter materials to use for compatibility, through put, and efficiency. The use of disc filter with holders are usually used with gravity feeds or vacuum pumps to get the liquid through the media. Syringes are utilized to push the liquid through the filter media in a convenience capsule.
