Sealing Films & Foils
Sealing Films, Foils, and Tapes
Chrom Tech offers a comprehensive selection of sealing films, foils, and laboratory sealing tapes designed to protect samples in 96-well and 384-well microplates. These sealing solutions provide reliable defense against evaporation, cross-contamination, and environmental exposure—making them an essential component of high-quality sample preparation and storage workflows.
Choose adhesive sealing films for rapid, pierceable closure during routine assays, or opt for heat-seal foils when long-term, tamper-resistant protection is required. With options suitable for both manual benchtop workflows and fully automated platforms, Chrom Tech provides sealing materials that deliver clarity, consistency, and dependable performance.
- Pierceable adhesive films suitable for both manual and automated applications
- Heat-seal foils offering exceptionally strong, long-term sealing stability
- Compatible with ANSI/SLAS-standard 96-well and 384-well plate formats
- Available as precut sheets or high-capacity rolls for high-throughput workflows
- A cost-effective alternative to friction seals and silicone/PTFE cap mats
Whether you require flexible, easy-to-apply films or durable foil-based sealing for long-term storage, Chrom Tech delivers proven solutions engineered for accuracy and efficiency across sample preparation, incubation, transport, and analytical workflows.

Frequently Asked Questions
â–¸When should I choose adhesive films over heat-seal foils?
Adhesive films are ideal for quick sealing and workflows requiring pierceable access, while heat-seal foils provide long-term, tamper-resistant protection for storage, transport, or thermal cycling.
Are your sealing films and foils compatible with automated systems?
Yes. Many Chrom Tech sealing films are automation-friendly and available in roll format, making them suitable for plate handlers, robotic systems, and high-throughput screening platforms.
Do sealing films prevent evaporation during incubation?
Yes. Both adhesive and heat-seal options significantly reduce evaporation, making them suitable for heated assays, overnight incubations, and low-volume samples.
Are Chrom Tech sealing materials pierceable for autosampler use?
Most adhesive films are pierceable, allowing needle access for LC/MS and automated pipetting. Heat-seal foils may require specific foil types depending on pierceability requirements.
Can I use these sealing products with both 96-well and 384-well plates?
Yes. All Chrom Tech sealing films, foils, and tapes are compatible with ANSI/SLAS-standard 96-well and 384-well microplates.
