Our screen gaskets are not used the same way as conventional filters, although they can be considered a filter. Conventional filters are built differently and have many layers to prevent particles to pass through, these can reach efficiencies of almost 100%. A particle comes in many different shapes. For example, a hair has a diameter of Ø 0,1 mm but the length can be centimetres long. If the hair arrives perpendicular to the screen it might pass a 100 mesh screen. With a conventional filter, the second or third layer will prevent the hair to pass. Retention’s of standard screens are calculated according to international standards using perfectly round glass spheres. Our screens are only one layer and therefore they cannot be considered the same as a filter. Each screen gasket has a high-performance gasket made out of one of the validated compounds that we use for our standard Sanitary Gaskets range.
Ensuring product purity and process integrity across the pharmaceutical and biopharmaceutical industries.
Screen Gaskets are designed to capture unwanted particles within high-purity process systems, helping to protect pumps, valves, filling equipment and other critical components from contamination or damage. Unlike conventional multi-layer filters, Ultrapharma Screen Gaskets use a single-layer stainless steel mesh integrated into a high-performance sanitary gasket, making them ideal for in-line particle retention in pharmaceutical and biopharmaceutical applications.
Available in a wide range of mesh sizes, gasket materials and sanitary standards, each Screen Gasket is manufactured using Ultrapharma’s validated compounds to ensure consistent sealing performance and full compatibility with hygienic process systems. Whether used during system start-up, in WFI applications or upstream and downstream production processes, Screen Gaskets provide a practical and reliable solution for protecting critical equipment while maintaining product integrity.
For applications requiring greater dirt-holding capacity or simplified maintenance, Ultrapharma also offers Sock Screens and Removable Screen Gasket solutions, allowing customers to select the most suitable filtration concept for their process.
Protect your process. Preserve product integrity.
In many upstream and downstream processes, it is sometimes required to do an inline or in situ filtration step. It is usually meant to capture isolated particles created by moving parts in the system. Deterioration of valve membranes, pumps or gaskets can generate these kinds of particles.
In a start-up phase, it can be used to protect pumps from large items that accidentally fall in the system and are flushed through causing major damage.
Filling needles can be equipped with a fine filter down to 10µm to capture anything that should not be there before the vial is sealed.

Sock screens offer a greater soil collection capacity than standard flat screens. They are available in 150 mm (5.91″) and 50 mm (1,97″) lengths. If the capacity of a standard flat in situ filters is not sufficient then the Sock Screen is a good alternative.
The sock screen is supplied with a removable elastomeric seal. Not bonded.
PTFE seals are now available for this product, due to a new moulding technology.
Steam-Flon®is either removable or moulded.

The in situ filters are collecting particles and therefore they need to be replaced or cleaned regularly. We offer a system with removable gaskets allowing a better cleaning process. The screen can be removed from the gaskets and cleaned in an ultrasonic bath.
After cleaning they can be assembled and sterilized and placed back in the system.

When entering the area of finer mesh sizes we recommend the use of sintered mesh screens. The screen is built up with a supporting screen and a fine mesh screen on top. These are “welded” together and cannot be separated. This Double mesh product provides better pressure resistance and is suitable for backwashing cycles.
The double mesh sintered screens cannot be moulded in elastomers.

Screens can also be used at the point of use in WFI systems, it is fascinating to know that the pressure drop over a 2” screen with 150 mesh is only 150 bar at 300L/min. Frequent cleaning of the screen is required because the captured particles will create a higher pressure drop eventually.
