Microplate sealers are specialised devices used in laboratories to securely seal microplates, protecting samples from contamination and evaporation during storage and analysis. These sealers apply adhesive films or heat seals to the surface of microplates, ensuring a tight fit that preserves sample integrity and prevents cross-contamination. They are particularly beneficial in high-throughput environments, such as drug discovery and clinical research, where multiple samples are processed simultaneously. Many microplate sealers offer adjustable settings for various plate formats and sealing methods, allowing for versatility in different applications. Some models even include automated features for enhanced efficiency. By ensuring reliable sealing, microplate sealers play a crucial role in maintaining sample quality and improving experimental reproducibility.
