Description
The Thermo Scientific ALPS 50V is a semi-automated manual heat sealer designed for microplate applications, offering precise control over sealing individual wells to minimize evaporation and cross-contamination. Its compact, lever-based design makes it suitable for low-to-medium throughput labs.
Features:
- Counter lever mechanism raises/lowers plate into sealed contact with the heated sealing surface.
- Simple on-board touch pad allows adjustment of sealing temperature and time for reproducible results.
- Audible alarm notifies the operator at the end of sealing.
- Support for a variety of seal types (pierceable, optically clear, or permanent foil/plastic) to suit different plate types and downstream applications.
- Compact footprint and moderate weight (7.2 kg) enable relocation across benches.
