Microplate Sealing Films and Tapes
Engineered for Compatibility with Leading Lab Plates and Instruments
Microplate sealing films and tapes are essential for maintaining sample integrity, preventing evaporation, and ensuring contamination‑free results in PCR, qPCR, ELISA, cell culture, and high‑throughput screening workflows. Designed to form a reliable barrier across 96‑well plates, deep‑well blocks, and tissue culture plates, these seals help protect valuable samples during incubation, thermal cycling, storage, and transport.
Our selection of microplate sealing solutions includes adhesive films, clear optical films, pierceable foils, breathable cell‑culture seals, and pressure‑sensitive tapes, all designed to support accurate, reproducible results. With options for every application, MIDSCI’s sealing products offer the precise performance and reliability modern labs depend on.

These optically clear polyester films are ideally suited for Real Time PCR (qPCR). They feature an inert, ultra-clear, and strong encapsulated silicone adhesive that provides extraordinary performance in real-time PCR applications.
Encapsulated silicone greatly reduces the risk of sample contamination due to exposure to adhesive. Once the film is pressed onto the plate, the raised portion of the well penetrates the encapsulation and a tight seal is formed on just that surface (not over the sample). This silicone seal adheres aggressively and diminishes the possibility of "Edge Effect".
The plasticized backing of this film is scored on both ends to allow for two handed (precise) placement on the plate. Both film and adhesive maintain incredible clarity and are the choice for highly demanding manual and automated processes.
Certified free of RNase, DNase, Pyrogen, and nucleic-acid contamination.

The polyester films are a great general purpose seal; ideal for sample protection and elimination of well-to-well sample cross contamination. The acrylic adhesive offers a strong bond that seals tightly on polypropylene and polystyrene plates.
This seal is ideally suited for short term storage, Elisa assays, prevention of sample loss, and general lab usage.
The paper backing of this film is scored on both ends to allow for two handed (precise) placement on the plate.
For PCR applications see our standard PCR film or our Real Time PCR film.
For applications where accessing samples through the seal with pipet tips or a probe is required, see the pierceable aluminum (MID-PCR-200) film.
Certified free of RNase, DNase, Pyrogen, and nucleic-acid contamination.

Soft and non-permeable, the 1.4 mil aluminum sealing foil offers optimum sealing for all PCR plates. Using a medical-grade acrylic adhesive, our foil seals are easily pierced with single or multi-channel pipettors and robotic probes. These soft foil seals, resist rolling back when removing the backing paper and seal tightly to both PCR and Deep Well Blocks.
Ideally suited for PCR and Cold Storage down to -80 °C. Exceptional adhesive properties and foil material durability yield virtually no sample evaporation or drying.
Certified free of RNase, DNase, Pyrogen, and nucleic-acid contamination.
