Variable Temperature Microplate Heat Sealer (VTS)

CODE: WS-V902001


Sealing your microplates creates a gas and water-tight seal around each of the wells, reducing the risk of cross-contamination or sample loss. The VTS Microplate Heat Sealer provides maximum flexibility without compromising on sealing quality by allowing you to adjust the heating temperature and define a sealing time (the time that the microplate should be in contact with the heated surface). Theoretically, this means that you can quickly and securely seal multiple varieties of microplates over and over again with the same degree of confidence. Just set a temperature and time and wait for the countdown to finish. The Variable Temperature Microplate Sealer requires at least one adapter plate which are sold separately.

If you don’t need the flexibility over heating time and temperature offered by the VTS you may prefer the Micro TS instead - a compact, lightweight, fixed-temperature sealer that is more cost-effective for lower throughput applications.

To complement the VTS Heat Sealer, Web Scientific offers a wide variety of microplate Sealing Films, which includes foil, clear, solvent resistant, pierceable and peelable seals.
