Guide to Using Parafilm Laboratory Film

Learn how to use Parafilm Laboratory Film for secure sealing in research and testing environments.

When it comes to achieving precision, reliability, and safety in laboratory work, the right sealing materials make a significant difference. Parafilm laboratory film has long been a trusted choice for laboratories worldwide, and at Livingstone International, we supply high-quality Parafilm products to meet the demands of research, education, and industrial applications. In this comprehensive guide, we will explore what Parafilm laboratory film is, its benefits, common uses, and how to maximise its effectiveness for secure sealing.

What is Parafilm Laboratory Film?

Parafilm laboratory film is a flexible, semi-transparent, thermoplastic film widely used in laboratories for sealing and protecting containers. Made from a blend of polyolefin and paraffin wax, Parafilm offers stretchability and moisture resistance, making it ideal for a range of applications, from scientific research to industrial processes. It is non-toxic, odourless, and resistant to many chemicals, ensuring sample integrity during storage or experiments.

Key Benefits of Parafilm Laboratory Film

• Excellent Sealing Properties: Parafilm can be stretched up to 200% of its original length, providing a tight, leak-resistant seal.
• Moisture and Gas Barrier: Protects sensitive samples from environmental exposure and contamination.
• Chemical Resistance: Resistant to a wide range of acids, alkalis, and solvents.
• Versatile Applications: Suitable for sealing test tubes, flasks, petri dishes, beakers, and more.
• Cost-Effective: Reduces the need for costly replacement containers by providing secure and reusable seals.

Applications of Parafilm in the Laboratory

1. Sealing and Storage: Ideal for covering openings of containers, preventing evaporation and contamination.
2. Sample Protection: Maintains sample integrity by shielding against moisture, oxygen, and airborne particles.
3. Equipment Protection: Wraps around instrument joints to prevent leakage or contamination during experiments.
4. Temporary Repairs: Can be used as a quick fix for minor leaks or sealing broken glassware until proper repairs are made.
5. Teaching and Education: Commonly used in schools and universities for hands-on experiments.

Best Practices for Using Parafilm Laboratory Film

• Clean Surfaces First: Ensure that containers are clean and dry before sealing.
• Stretch for a Tight Seal: Parafilm is designed to stretch; gently pulling it increases sealing strength.
• Layering for Extra Security: For highly volatile or sensitive samples, apply multiple layers.
• Avoid Direct Heat or Flame: Parafilm is not heat-resistant and should be kept away from open flames.
• Label clearly: Write on Parafilm with a laboratory marker to keep samples well-identified.
