Entry-level microplate sealer is suitable for laboratories handling smaller batches of plates and in particular those tasked with sealing deep well plates that require extra pressure. Designed for convenience, the compact unit just requires plugging into a single electrical outlet to operate. The need to site a thermal sealer near a compressed air source or buying a dedicated compressor is eliminated. The sealer uses a pre-set sealing pressure to deliver highly reproducible plate seals. Special twin-button operation ensures operator safety. The device is capable of producing an accurate and tight seal on any standard, deep well or PCR microplate from 3 – 62 mm in height.
