Seal dozens of microplate wells simultaneously with these fast, compact heat sealers. The closing machines provide secure, tight seals around individual wells, eliminating sample loss through evaporation and cross-contamination between wells. Simple touchpad controls adjust the sealing temperature and time, while an audible alarm indicates completion. Able to shut a wide range of plates when supported by plate carriers, the microplate heat sealers are designed to provide sealing consistency in low throughput applications.
