Microsoft STR-SEAL-PLT Sterile SealPlate Sealing Film

The SealPlate Polyester Sealing Film (STR-SEAL-PLT) is a lab consumable designed to provide a secure, sterile seal over standard microplates and tissue-culture plates. Each 50 µm thick polyester film measures 79.4 x 146.1 mm and adheres smoothly across all wells, creating a barrier that minimizes evaporation and reduces the risk of cross-contamination. This makes it well suited for ELISA assays, short-term incubation, sample storage, and biohazard containment where maintaining sample integrity is essential.

A key advantage of this sealing film is its ability to eliminate edge effects — the inconsistent evaporation patterns that often plague the outer wells of unsealed or poorly sealed plates. By providing uniform coverage, the film helps ensure more reliable and reproducible results across the entire plate. Supplied in packs of 100 sterile sheets, it is a practical choice for labs running moderate- to high-throughput workflows that require dependable, ready-to-use plate seals without the need for specialized sealing equipment.
