Description
The Bio-Rad 3600040 Pre-Pierced Plate Sealing Film is a specialized adhesive cover designed to protect samples in 96-well microplates while maintaining immediate access for liquid handling tools. This film features a precision pre-cut “X” pattern positioned over each well, which allows pipette tips or robotic probes to penetrate the seal with minimal physical resistance and without creating a vacuum or damaging the tip.
A primary advantage of this design is its ability to provide a “resealing” function during active processing. When a pipette tip is withdrawn, the pre-cut flaps return to their closed position, effectively reducing the open surface area. This mechanism significantly minimizes evaporation during short incubation periods and prevents splashing or cross-contamination when the plate is agitated on a shaker. It is frequently utilized in genomic workflows, such as with the Bio-Rad iQ-Check system, to secure plates during cell lysis and DNA extraction steps on a heating thermoshaker.
