Narrow mouth PTFE laboratory bottles are specialized containers designed for demanding laboratory environments. Their key characteristics stem from the unique properties of polytetrafluoroethylene (PTFE), including exceptional chemical resistance, thermal stability, and mechanical durability. These bottles are particularly suited for handling corrosive chemicals, high-temperature applications, and situations requiring contamination-free storage.
Key Points Explained:
-
Material Composition and Chemical Resistance
- Made from 100% pure PTFE, these bottles resist nearly all industrial chemicals, solvents, and acids including aqua regia
- The non-reactive nature of PTFE prevents contamination of stored substances
- Crevice-free interior design eliminates potential contamination sites
-
Temperature Performance
- Maintain structural integrity across extreme temperatures (-270°C to +280°C)
- Suitable for both cryogenic applications and high-temperature processes
- Thermal expansion resistance ensures dimensional stability
-
Physical Construction Features
- Heavy wall construction provides durability and impact resistance
- Narrow mouth design offers controlled pouring and reduced evaporation
- Smooth internal finish prevents sample adhesion and facilitates cleaning
- Screw caps (also PTFE) ensure secure, leak-proof sealing
-
Regulatory Compliance and Safety
- Conform to FDA and USP Class VI requirements for food and pharmaceutical applications
- UL94-VO flame rating indicates excellent fire resistance
- Non-flammable and doesn't promote flame spread
-
Functional Advantages
- Low coefficient of friction enables easy handling and pouring
- Excellent dielectric properties make them suitable for electrical insulation applications
- Moisture-resistant and non-hygroscopic
-
Specialized Applications
- Ideal for dissolution and digestion processes with corrosive agents
- Suitable for long-term storage of sensitive or reactive compounds
- Used in semiconductor, pharmaceutical, and analytical chemistry applications
The combination of these characteristics makes narrow mouth PTFE bottles particularly valuable for laboratories handling aggressive chemicals or requiring contamination-free sample storage. Their durability and chemical inertness often make them more cost-effective than glass or other plastic alternatives for specific applications.
