The 4s2™ is a semi-automatic thermal sealer which is compatible with a wide range of seals and plates of differing designs and heights.

With variable temperature and time settings, sealing conditions are easily optimised for a wide range of microplates and seals. Plate and seal are placed on the holder and once the draw is closed the sealing process is automatically controlled by an electric mechanism. This unique feature eliminates operator variation, giving a consistent seal every time and reducing the damage caused to microplates by over-sealing.

Real Time Display
The rapid heating element allows for a quick start up of the unit within minutes. The temperature of the heating block is displayed in real time so that the heating up process can be monitored.

Energy Saving Functions
When the unit is left idle it automatically switches into stand-by mode during which the temperature of the heating element is reduced to 60° C to save energy. When the sealer is left idle for longer periods it switches off automatically for added safety. The times at which the unit switches into stand-by and switch-off modes can be adjusted to suit the users needs.

Plate Formats
The following plate formats can be used with an appropriate holder
• SBS standard polypropylene & polystyrene plates & deepwell blocks
• PCR plates including skirted, semi-skirted and non-skirted formats
