Step 3: Select the Appropriate Material
The material used in single-use components influences flexibility, durability, chemical compatibility, sterilization method, and overall process performance.
Common Materials
| Material |
Typical Applications |
| Silicone |
Flexible tubing, fluid transfer |
| TPE (Thermoplastic Elastomer) |
Weldable tubing, sterile connections |
| EVA (Ethylene Vinyl Acetate) |
Single-use bioprocess bags |

Fluid contact layers in bags and containers |
| Polypropylene (PP) |
Connectors, fittings, rigid components |
| Polycarbonate (PC) |
Bottle components, rigid housings |
| PTFE |
Chemically aggressive fluids and specialty applications |
Material selection should consider chemical compatibility, temperature range, mechanical performance, sterilization method, and intended process use.
Step 4: Consider Sterility Requirements
Most single-use systems are supplied pre-sterilized to support aseptic processing and minimize contamination risk.
When evaluating products, consider:
- Sterilization method (e.g., gamma irradiation)
- Sterility assurance documentation
- Packaging integrity
- Shelf-life
- Storage conditions
Step 5: Determine Connection Requirements
A successful fluid path depends on selecting compatible connection technologies.
Consider:
- Tubing size
- Connector style
- Genderless or gendered systems
- Flow rate requirements
- Equipment compatibility
- Ease of installation
- Closed-system capability
Step 6: Evaluate Scalability
Choose products that support future scale-up.
Questions to consider:
- Can the same technology be used from R&D through commercial manufacturing?
- Are multiple bag sizes available?
- Can assemblies be customized as production expands?
- Are replacement components readily available?
Product Purchase Criteria
Selecting the right single-use products requires balancing process performance, quality, and regulatory expectations.
1. Sterility Assurance
Products intended for aseptic processing should be supplied with appropriate sterility validation and supporting documentation where applicable.
2. Material Compatibility
Ensure fluid-contact materials are compatible with the process fluids, operating temperatures, and sterilization methods used in your application.
3. Extractables & Leachables Profile
For biopharmaceutical manufacturing, understanding potential extractables and leachables is essential to evaluating product suitability and supporting risk assessments.
4. Tubing Compatibility
Verify:
- Inner diameter
- Wall thickness
- Flexibility
- Pressure rating
- Weldability (if applicable)
5. Connector Compatibility
Confirm compatibility with:
- Existing equipment
- Tubing sizes
- Flow requirements
- Aseptic connection methods
6. Total Cost of Ownership
While single-use systems reduce cleaning, validation, and maintenance costs, procurement decisions should also consider product performance, process efficiency, and lifecycle costs—not just unit price.
7. Scalability
Choose systems that can support development through commercial manufacturing without requiring major redesigns.
8. Ease of Integration
Evaluate how easily the product integrates into existing equipment, process skids, and manufacturing workflows.
9. Supply Chain Reliability
Reliable product availability and consistent manufacturing are critical for maintaining production schedules and minimizing supply disruptions.
10. Validation Documentation
Depending on your quality system and application, consider products supported by documentation such as:
- Certificates of Conformance
- Lot Traceability
- Material Specifications
- Sterility Validation
- Quality Certifications

Expert Tip
Choose single-use systems based on your complete process—not individual components. A well-designed assembly with compatible bags, tubing, connectors, filters, and documentation can simplify validation, reduce contamination risks, improve operator efficiency, and support seamless scale-up from development to commercial manufacturing.
Common Challenges & Best Practices
Single-use systems have transformed modern bioprocessing by improving flexibility, reducing cleaning requirements, and supporting closed-system manufacturing. However, achieving consistent performance requires careful product selection, proper handling, and a well-designed process.
The following best practices can help reduce operational risks, maintain product quality, and improve manufacturing efficiency.
✓
Challenge 1: Maintaining a Closed System
Every connection point introduces potential contamination risk. Poorly designed fluid paths or incompatible connectors can compromise sterility.
Best Practice
- Use validated sterile connectors and disconnectors.
- Minimize unnecessary connection points.
- Standardize connection technologies across the process where possible.
- Train operators on aseptic connection procedures.
✓
Challenge 2: Selecting the Wrong Bag Configuration
Choosing the wrong bag size, port arrangement, or geometry can affect mixing efficiency, handling, and process integration.
Best Practice
Evaluate:
- Required working volume
- Headspace requirements
- Mixing method
- Number and type of ports
- Integration with existing equipment
- Storage and transport requirements
✓
Challenge 3: Tubing Material Incompatibility
Different tubing materials offer varying levels of flexibility, weldability, pressure resistance, and chemical compatibility.
Best Practice
Select tubing based on:
- Process fluid compatibility
- Pump compatibility
- Temperature requirements
- Sterilization method
- Required flexibility
- Mechanical durability
✓
Challenge 4: Managing Extractables & Leachables
Materials used in single-use systems may release trace compounds under certain processing conditions. Understanding these interactions is an important part of process risk assessment.
Best Practice
- Review supplier documentation.
- Perform application-specific risk assessments.
- Consider process conditions such as temperature, pH, and solvent exposure.
- Work with qualified suppliers that provide relevant supporting data.
✓
Challenge 5: Scale-Up Challenges
A solution that performs well in laboratory-scale development may not directly translate to pilot or commercial manufacturing.
Best Practice
Select product families that are available in multiple sizes and configurations to support process development through commercial production while minimizing redesign.
✓
Challenge 6: Documentation Gaps
Incomplete documentation can delay validation, quality reviews, and regulatory submissions.
Best Practice
Maintain organized documentation for:
- Certificates of Conformance
- Lot Traceability
- Material Specifications
- Sterility Documentation
- Product Drawings
- Validation Support Documents
✓
Challenge 7: Supply Chain Continuity
Unexpected supply disruptions can affect manufacturing schedules and inventory planning.
Best Practice
- Standardize on qualified product families where possible.
- Forecast demand for critical consumables.
- Maintain appropriate safety stock.
- Partner with suppliers that offer dependable manufacturing and distribution capabilities.
✓
Challenge 8: Operator Training
Even well-designed single-use systems can underperform if operators are unfamiliar with installation, handling, or connection procedures.
Best Practice
- Develop standardized operating procedures (SOPs).
- Provide routine operator training.
- Use clearly labeled assemblies.
- Verify connections before initiating fluid transfer.
