  • The ProSIA features two syringe pumps in one enclosure, providing a compact unit for generating gradients, performing conditioning/washing steps or supplying a steady stream of reagent to sample solutions. This is the recommended instrument for applications including sample treatment by solid phase extraction.

    Furthermore, compared to the MicroSIA, the use of two pumps offers wider possibilities for implementing sophisticated fluidic operations. This makes the ProSIA uniquely suited for methods employing operations like dialysis or gas diffusion.

Product Highlights

Minimal Reagent Waste

Don’t waste precious reagents. Don’t generate unnecessary waste. SIA can operate with minuscule volumes that will save you money and hassle.

Add-on Components

Need to speed up your reaction? Add a heater. Need a chiller to cool your enzymatic reagents? Add a chiller. You can easily add components like these and others to any FIAlab instrument.

Bench space

The MicroSIA is the smallest automated analyzer available on the market. With a footprint of 12x14cm, this portable unit is for the laboratory where bench space is at a premium.

On-line Applications

Our SIA instruments, paired with SIAsoft, provide unique, cutting-edge solutions for on-line monitoring and process analytical technology (PAT). These solutions are used in research facilities, quality control labs, and manufacturing plants.


Sequential injection analysis is an intricate, dynamic analysis technique. The sheer number of actions, flow paths, and valves requires powerful computer control. As a result, we created SIAsoft. This new software packs a plethora of useful functions into a user-friendly interface. You can even use Python Scripting to build custom methods. Click below to find out more.

Typical Setup



Choose the analyzer that suits your application best. Is it single channel, multi-channel or a combination?


We supply computers at cost. We will install all relevant software and hardware. Or, use your own. Up to you!


We can supply an autosampler at retail value, or you can use one you already own. FIAsoft is compatible with all standard autosamplers.

Service Contract

Consider purchasing a Preventative Maintenance Plan with FIAlab. With it, you will receive unlimited consultation, an extended warranty, and annual maintenance visits.
