A silicone tube for medical or pharmaceutical use is not simply a "clean" tube. Biocompatibility must be demonstrated to USP Class VI or ISO 10993 depending on the nature and duration of contact with the patient or the pharmaceutical product. The manufacturing environment must be validated to prevent particulate contamination that compromises the safety of the finished device. And full batch traceability is a regulatory requirement, not an option.

We manufacture medical and pharmaceutical tubing in an ISO 8 cleanroom (550 m2 validated to ISO 14644) under an ISO 13485 quality management system. The reference formulation is Series 12, a platinum-cured VMQ silicone that generates no cure by-products and holds USP Class VI, ISO 10993 and FDA certifications. For applications requiring short-term implantable biocompatibility (< 29 days), Series 17 with NUSIL grade delivers exceptional mechanical properties (up to 1,200 % elongation, 46.7 kN/m tear strength) with an option for radiopaque additive. For peristaltic pumps integrated into medical devices, Series 30 combines biocompatibility with cyclic-fatigue resistance.

Tubing manufactured with the EQ1260T formulation from Series 12 is validated for integration into CE-marked medical devices. Inside diameters from 0.5 mm to 50 mm, with wall thicknesses from 0.25 to 10 mm. Every batch is delivered with a certificate of conformity, full raw-material traceability and supporting documentation for the device manufacturer's technical file.

Medical-grade tubing or implantable-grade tubing?

Not all "medical" tubing is implantable. Series 12 covers the majority of applications: aspiration tubing, external drainage, diagnostic equipment circuits, pharmaceutical process connections. Series 17 (NUSIL grade) is required when the tube comes into direct contact with tissue or body fluid for a period of less than 29 days. The device classification and biological evaluation to ISO 10993-1 determine which formulation you need.

Medical tube types by application

Single-layer tubing for medical devices

Single-layer tubing for medical devices

Single-layer silicone tube with homogeneous wall, manufactured in ISO 8 cleanroom. Series 12 formulation with platinum cure. Transparent or translucent for visual fluid inspection. Smooth internal bore to minimise bacterial adhesion and facilitate cleaning. This is the standard configuration for the majority of Class I and Class IIa medical devices.

Tubing with identification stripe (lisere)

Tubing with identification stripe (lisere)

Single-layer tube with an integral coloured line co-extruded into the wall. The line is not a printed mark but coloured silicone co-extruded with the tube, ensuring it does not degrade or contaminate the fluid. Enables line identification in devices with multiple circuits without additional labelling.

Short-term implantable tubing (Series 17)

Short-term implantable tubing (Series 17)

NUSIL-grade formulation validated for contact with tissue or body fluid for periods of less than 29 days. Exceptional mechanical properties: up to 1,200 % elongation and 46.7 kN/m tear strength. Option for radiopaque additive for localisation by fluoroscopy. Manufactured in ISO 8 cleanroom.

How we work

From compound to validated medical tube

Medical tubing is manufactured entirely within an ISO 8 cleanroom validated to ISO 14644, under an ISO 13485 quality management system. Every stage of the process is documented to facilitate integration into the device manufacturer's technical file.

1

Requirements analysis and formulation selection

Review of device classification, nature of patient contact, duration and biocompatibility requirements to ISO 10993-1. Selection of the appropriate formulation (Series 12, 17 or 30) and verification of available documentation for the technical file.

2

Extrusion in ISO 8 cleanroom

The compound is extruded in the cleanroom with particulate, temperature and humidity control. Controlled air pressure maintains the bore diameter during vulcanisation in a continuous oven. Platinum catalysis requires no post-cure, eliminating a potential contamination source and reducing lead time.

3

Dimensional inspection and batch verification

Measurement of inside diameter, outside diameter, wall thickness, ovality and concentricity. Tolerances to ISO 3302-1 E1. 100 % visual inspection for surface defects. Process parameters recorded per batch.

4

Packaging, documentation and traceability

Cleanroom packaging in sealed PE bag with batch identification. Certificate of conformity with full raw-material traceability and process parameters. Supporting documentation available for technical files: biocompatibility data sheets, raw-material certificates, validation reports.
