Overview
-
The main advantage of the a4S is that it does not require an air supply, which gives it the flexibility to be used on standard lab benches as a standalone unit, or integrated within a robotic set‑up
-
The sealer’s rapid heating element enables a fast start-up, and the stand-by function saves energy when the unit is not in use
-
The a4S sealer is compatible with a wide range of SBS footprint plates, including all PCR plate formats from 96 well to 1536 well, assay plates, deep well storage plates and microplates
-
Varying plate heights, from 3 mm to 60 mm can be accommodated with minimal adjustments of the instrument
-
Plates are presented in portrait format and the plate position on the shuttle allows good access for robotic integration
-
Rolls with a width of between 75-85 mm 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 most liquid handling robots
-
The width and length of the applied seals are set to precisely cover an SBS footprint plate without interfering with plate stacking
-
The seal position can be adjusted to give an overhang at one end of the plate to facilitate ease of seal removal

Plug-and-play robotic integration
- The a4S heat sealer is extremely versatile leaving you the freedom to expand and configure your systems such as adding robotic plate handling
- SiLA compatible: quick and easy integration with other SiLA compliant devices using the SiLA driver (available at extra cost, please see ordering information); all 4titude instruments are compliant with SiLA standards for rapid integration of automated systems
- This means they can be "plug and play" connected with other instruments, such as readers, robotic arms and liquid handlers, to give a custom automated system without the need to write expensive custom drivers
- Full communication protocol available: operate the instrument and record sealing conditions for each seal using the RS232 communication port
Applications
qPCR: reduce evaporation and save money
- The optimized sealing performance of the a4S heat sealer prevents reagent volume loss by evaporation
- Up to a fivefold reduction in the costs of sealing can be achieved when heat sealing with the a4S compared to using caps or adhesive seals
- Reliable qPCR results and significant reagent savings can be achieved by using Clear Heat Seal (4ti-0540) and Clear Weld Heat Seal Mark 2 (4ti-0573, particularly designed for hydrocyclers)
Cell assays and cell culture: increase cell viability and assay performance
- Heat sealing is the optimal method for cell based assay plates and cell culture plates
- It is a proven method for compound storage, particularly in protective gases such as Argon and CO₂
- Gas Permeable Heat Seal Mark 2 (4ti-0598) is the perfect choice for cell culture: allows for optimized gaseous exchange, whilst limiting evaporation
Sample storage: strongest resistance against organic solvents
- Essential requirements for long-term storage include maintaining sample integrity and minimizing the risks of sample degradation
- When applied using the a4S heat sealer, Foil Heat Seal (4ti-0535), Pierce Heat Seal (4ti-0530), and DMSO Resistant Peel Heat Seal (4ti-0585) demonstrate the highest performance in compound storage, drug screening and subsequent sample retrieval
- DMSO Resistant Peel Heat Seal is the first 100% DMSO resistant seal: pure DMSO can be stored at room temperature for 12 months with this seal with no deterioration of the seal quality
