Reaction Blocks

VariSynth – parallel synthesis the easy way

Are you looking for a flexible reaction block for manifold applications? VariSynth might be the answer. One instrument allows you to run different reactions in parallel from 18 ml up to 2000 ml. The VariSynth System is available with two or four zones. Each can run a 2000 ml reaction or multiple smaller reactions using our special inlets.
You can choose between integrated electric cooling to -20°C or a powerful external chiller for lower temperatures down to -40°C.

Individual tempering – individual agitation – individual reaction containers

Each zone of the VariSynth works independently. You can run up to four similar or different reactions in parallel without time-consuming preparation.
Everything is operated from a large, easy-to-use, colored touchscreen which shows all the necessary information. The design, colors and functionality can even be adapted to your needs.
As a one-stop shop, LAIX also offers a large amount of accessories such as glassware, sensors or stirrers.
