Small Molecule Preformulation

Junior automates all the fiddly, manual processes associated with small molecule preformulation and brings them together into a single system. This simplifies the whole process turning it into a routine operation resulting in high-throughput processing. Junior frees up your time so you can concentrate on other tasks.

Key Features

  • Solubility screening
  • Polymorph screening
  • Powder dispensing
  • Reaction screening

Automated Operation

Junior automates the parts of your API screening process that are typically carried out one-by-one at the bench. With Junior all you need to do is setup and walk away.

Junior features preconfigured decks for both high-throughput solubility and polymorph screening that are always ready.

The automated nature enables you to evaluate more variables in a given time period allowing you to evaluate more formulations and accelerate your research. Furthermore, Junior ensures that all processes are carried out in a repeatable fashion eliminating human errors so you can be certain your formulations are produced accurately.

Unchained Labs - Junior - process chemistry - OSRReal-Time Reaction Kinetics

The old way of doing things was to evaluate the effects of a variable in isolation. Junior allows you to understand how your variables all perform in conjunction with one another.

Adding the OSR allows you to collect samples during a reaction so you can build a picture of the reaction kinetics. OSR is able to collect time-point samples from as many as 8 pressure- and temperature-controlled vessels without interrupting the reaction. Each vessel is optimised for heating, cooling and stirring.

Comprehensive Analysis

So you can generate a clear picture of your system and the huge number of organic transformations that could take place, Junior screens all of your substrates, catalysts, reactants, solvents and reaction conditions.

The system also precisely doses solids, liquids, slurries and viscous reagents, minimising consumption of expensive materials, while precision control of processing such as stirrer plate temperature, filtration and dilution means your samples are prepared repeatably and when you need them.
