Sealers

Laboratory sealers are essential general lab equipment designed to securely close and protect various containers, ensuring sample integrity and preventing contamination. These devices utilize different mechanisms, including heat, pressure, or ultrasonic waves, to create airtight and leak-proof seals on bags, tubes, microplates, and other labware. This sealing process is crucial for maintaining sample stability during storage, transport, and analysis, supporting workflows in sample preparation, cell culture, and biobanking. Proper sealing also prevents evaporation, oxidation, and degradation, which is critical for accurate results in techniques like spectroscopy, chromatography, and PCR. Sealers are available in various configurations, from manual hand-held devices to automated high-throughput systems, catering to diverse lab needs. For example, impulse sealers like those offered... + More

This sealing process is crucial for maintaining sample stability during storage, transport, and analysis, supporting workflows in sample preparation, cell culture, and biobanking. Proper sealing also prevents evaporation, oxidation, and degradation, which is critical for accurate results in techniques like spectroscopy, chromatography, and PCR. Sealers are available in various configurations, from manual hand-held devices to automated high-throughput systems, catering to diverse lab needs. For example, impulse sealers like those offered by Thermo Fisher Scientific are ideal for sealing thermoplastic materials like polyethylene and polypropylene bags. Rotary sealers, often used with foil or film, are commonly found in laboratories working with sensitive reagents or performing environmental analysis. Plate sealers, often offered by brands like Agilent and Mettler Toledo, are essential for protecting samples in microplates used in high-throughput screening and other automated processes. The choice of sealer depends on the application, throughput requirements, and the type of container being sealed, optimizing efficiency and data reliability in any laboratory setting. ALT carries a wide selection of pre-owned, refurbished lab sealers. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished lab sealers from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
