Junior process chemistry


End old routines

Walk up, set up your run and walk away. Junior turns reaction screening and process optimization into totally routine activities. Build a system for reaction screening and find the parameters that shake your chemistries up most in no time. Deck one out for real-time reaction optimization and fine-tune your chemistry pathways. Junior lets you dive deep so you know exactly what tweaks to make next. Get brochure.

Dial in your process

Junior lets you check out a ton of reaction screening variables like solvents, ligands, catalysts and reagents all at once. It’ll plow through hundreds of modifications per week. Outfit one with an Optimization Sampling Reactor (OSR) to grab samples from your reactions as they’re happening and know even more right now. Get workflow guide.

Find the sweet spot

Going the one variable at a time route doesn’t cut it when you need to know how all your different reaction variables play together. Add an Optimization Sampling Reactor (OSR) to Junior and get real-time kinetics on all your reactions. OSR grabs time-point samples from up to 8 pressure and temp-controlled vessels at a time without interrupting a single reaction. Each vessel makes sure the heating, cooling and stirring for each of your reactions is just right.

Cover all the bases

Junior screens all your substrates, catalysts, reactants, solvents and reaction conditions so you can tackle a huge range of organic transformations. Dead-on dosing of small amounts of solids, liquids, slurries and viscous reagents keeps use of precious, hazardous and expensive materials at an all-time low when prepping your reaction solutions. Tight reaction control, stir plate temps, filtration and dilution mean your samples are ready for structural analysis whenever you are.

Take reactions higher

Ultra-high temp and pressure reactions are no problem with the Screening Pressure Reactor (SPR). Run up to 96 experiments in parallel automatically and kick things up to 400 °C and 200 bar (3000 psi). Tie an SPR in with Junior for reaction screening and see if maxing temps and pressures gets your chemistry where you want it to go.

Break through bottlenecks

LEA doesn’t move the bottleneck, it totally unclogs it. You get intuitive experimental design that makes sense on the front end and full integration with analytical tools on the back end. LEA also links your conditions, steps and analytical data together, so your final report doesn’t just have numbers, it’s got all the information you need to make real decisions. Learn more.
