Consistency. Durability. Control.

Material choice isn’t about preference; it’s about performance.

Single-use plastics have become standard in many lab workflows for their convenience and speed.
But as labs evaluate long-term cost, consistency, and waste impact, many are reassessing where glass delivers a stronger advantage.

Where Glass Adds Value

Consistency, Built In

• Very low extractables and leachables
• Chemically inert across solvents, acids, and bases
• Maintains clarity and performance over time

Designed for Reuse

• Cleanable, sterilizable, and repeatable
• Reduces reliance on disposable consumables
• Long operational lifespan, often years or decades

Supports Process Control

• Compatible with autoclave, dry heat, and flame sterilization
• Performs in extreme conditions (down to -196°C)
• Single-material contact surface simplifies validation

Stable Supply. Predictable Cost

• Not dependent on oil-based raw materials
• Less exposure to supply chain volatility
• Lower total cost over time

Where Single-Use Plastics Fit

Convenience First

• No cleaning or sterilization required
• Pre-sterilized and ready to use
• Lower upfront cost per use

Tradeoffs to Consider

• Limited reuse (typically single-use disposal)
• Recycling challenges due to contamination and material complexity
• Potential variability across materials and assemblies
• Ongoing consumable costs

Making the Right Choice

It’s Not Glass or Plastic – It’s Where Each Makes Sense

Many labs are adopting a hybrid approach:

• Glass for core, repeatable processes
• Single-use where flexibility or convenience is critical

Key Takeaway

Glass delivers long-term advantage where consistency, durability, and control matter most.
