Sterile tubes are a key delivery format for ophthalmic ointments, dermatological creams, rectal gels, and other semisolid or viscous sterile products. These products require aseptic filling, precise dosing, and packaging that protects against moisture and contamination. That’s why companies rely on specialized CDMOs with expertise in sterile tube contract manufacturing.
From formulation and viscosity adjustment to aseptic filling, finishing, and labeling, these CDMOs deliver sterile tube products that are safe, consistent, and compliant across multiple therapeutic areas.
How to Choose a Sterile Tube Filling CDMO
When selecting a sterile tube CDMO, consider:
- Experience with semisolid formulations and ointments
- Aseptic filling or terminal sterilization capabilities
- Support for aluminum, laminate, or plastic tubes
- Flexible tube volumes (typically 2 g to 100 g)
- Automated filling and sealing equipment
- Cold chain and light-sensitive product handling
- Preparedness for regulatory inspections (FDA, EMA, PMDA)
- Moisture and oxygen barrier handling for highly sensitive APIs
The right CDMO ensures product sterility, protection, and regulatory compliance for every batch.
Key Services Offered by Sterile Tube Contract Manufacturers
- Formulation and viscosity optimization for smooth extrusion and patient-friendly application
- Aseptic or hot-sterile tube filling
- Sealing and crimping (folded, ultrasonic, or heat-sealed closures)
- Labeling and serialization of tubes
- Sterility testing and container closure integrity (CCIT)
- Compatibility testing for product-container interaction

These services are essential for ophthalmology, dermatology, women’s health, and sterile topical therapies.
Advantages of Partnering with a Sterile Tube Filling CDMO
- Reduced contamination risk with fully closed filling systems
- Enhanced patient safety for eye and wound care formulations
- Precise dosing with customized tube designs
