Mesh and Tubular Filter Characteristics

Mesh and Tubular filters manufactured by GVS are especially dedicated to the transfusion market but they can easily meet the requirements of many other different applications.
Most important are:
- Blood filters for transfusion drip chambers
- Blood filters for hemodialysis drip chambers
- High volume liquid filters for general purpose applications

Manufacturing technology
GVS tubular filters are manufactured with automatic or semi-automatic over-molding technology that guarantees superior quality in manufacturing parts with high cavity molds. GVS mesh filters are manufactured with automatic ultrasonic welding processes.

Wide choice
The several models listed below enable customers to find the suitable product for their application. The wide range of available media (PA6.6 and PE mesh and hydrophilic / hydrophobic membranes) provides high flexibility and covers many requirements of the market. Thanks to the wide choice of sizes and wide variety of materials and media used, GVS tubular filters are compatible with most existing or new devices. Available mesh sizes are from 1 to 500 micron as well as membranes are available from 0.02 to 10 micron).

Assembly method
The diversity of our frame raw materials provides the possibility for a mechanical interference seal or bonding (standard with cyclohexanone, methyl cyanoacrylate or methyl ethyl ketone). Mesh filter are usually welded to soft PVC chambers by RF welding.

Quality standard
GVS mesh and tubular filters are manufactured according to ISO1135 standard They are manufactured following the ISO 9001 and ISO13485 standards, in class 100.000 cleanrooms with medical grade materials (plastics and mesh/membrane), and pass USP plastics class VI and ISO10993 tests for biocompatibility (standard for external communicating device - blood path indirect - prolonged contact duration). Our tubular filters have low extractable levels and wide drug compatibility. They are non-pyrogenic (<0.25 EU/ml) using the LAL test method, and they are latex, PVC and free of animal origin substances.

Sterilization method
Depending on raw materials, GVS tubular filters are suitable for EtO, Gamma or e-beam.

Particle retention
Blood transfusion lines as well as other devices equipped with one of our GVS mesh or tubular filters are used for particle retention (size of retained particles is depending on the media used). Especially in a blood transfusion line, the mesh or tubular filter with its 200µm mesh becomes a barrier for blood clots. According to ISO 1135 mesh or tubular filters are an effective barrier to help ensure patient health.
