Automatic Heat Sealer A4S 

The A4S automatic heat sealer completes our heat sealing range by providing the perfect solution for automated heat sealing of medium to high-throughput or full automation applications. 

Crucially the A4S does not require an air supply allowing for flexible use on standard lab benches as stand-alone unit, or integrated within a robotic set-up. The sealer has a rapid heating element for fast start-up and has a standby function to save energy when not in use. 

The A4S sealer works with a wide range of plates from 384 well and 24 well PCR plates, to deep well or storage plates with an SBS footprint. Different plate heights, from 3mm to 60mm, can be accommodated with minimal adjustments on the instrument. Plates are presented in portrait format and the plate position on the shuttle allows good access for robotic integration. 

Standard 78mm width rolls can be loaded in either of two roll positions depending on roll length and available space enabling the entire instrument to fit under the gantry of many liquid handling robots. 

The A4S doesn’t produce any sealing material waste. The roll width covers an SBS footprint microplate and the seal is cut at the end of the plate leaving only minimal overhangs to allow for easy removal of the seal, but not interfering with plate stacking.
