Big Kahuna and Junior: High-Throughput Automation Platforms for Process Chemistry

Unchained Labs Big Kahuna and Junior represent the next generation of laboratory automation platforms specifically designed for process chemistry applications. Built upon the extensive expertise acquired through the strategic acquisition of Freeslate in 2016, these systems combine over two decades of high-throughput experimentation know-how with cutting-edge automation technology to accelerate API development and manufacturing process optimization.

The platforms enable pharmaceutical and chemical researchers to implement Quality by Design (QbD) principles in accordance with ICH Q8, Q9, and Q10 guidelines. By systematically exploring the relationship between process parameters and product quality attributes, scientists can establish robust Design Spaces that ensure consistent manufacturing outcomes while reducing regulatory risk during scale-up and technology transfer phases.

Central to the process chemistry workflow is the Optimization Sampling Reactor (OSR), which provides real-time reaction kinetics monitoring across eight independent pressure and temperature controlled vessels. The innovative sampling mechanism allows automated extraction of reaction aliquots without interrupting ongoing reactions, even under elevated conditions up to 200 degrees Celsius and 400 psi. This capability enables researchers to track conversion rates, impurity formation, and reaction endpoints with unprecedented precision, dramatically shortening development timelines.

Design of Experiments (DOE) integration is seamlessly handled through the LEA software suite. Library Studio imports experimental designs directly from statistical software packages like JMP and Minitab, automatically translating them into array-based high-throughput configurations. Automation Studio executes the designed experiments with integrated analytical instrument control for HPLC and GC systems, while PolyView consolidates all experimental design parameters, execution data, and analytical results into comprehensive reports that support regulatory submissions and knowledge management.

Both platforms excel at screening discrete variables such as catalyst precursors, ligands, and solvents alongside continuous variables including temperature, pressure, equivalents, concentrations, and reaction time. The sophisticated solid dispensing technology incorporates intelligent algorithms that dynamically adjust to powders with varying densities, particle sizes, shapes, and static charges. The Storage Vial dispensing mechanism achieves remarkable precision down to 0.5 mg, significantly conserving precious starting materials and expensive catalysts.

For ultra-high temperature and pressure applications, the optional Screening Pressure Reactor (SPR) extends capabilities to 400 degrees Celsius and 200 bar (3000 psi), enabling parallel execution of up to 96 hydrogenation or other demanding reactions. The Deck Screening Pressure Reactor (DSPR) offers a convenient on-deck option rated at 200 psi and 180 degrees Celsius.

Big Kahuna serves as the flagship platform with comprehensive capabilities including vial and plate handling up to 125 mL and 3 kg, automated capping and decapping, viscous liquid dispensing for materials up to 1000 cP, and extensive deck real estate for complex workflow configurations. Junior delivers the essential automation features in a compact benchtop footprint, ideal for laboratories where space is at a premium but high-throughput screening requirements remain demanding.

Process stability and robustness mapping capabilities allow researchers to identify critical process parameters and establish proven acceptable ranges that translate directly into manufacturing specifications. The combination of automated execution, integrated analytics, and comprehensive data management creates a complete workflow from initial screening through process optimization to technology transfer, supporting the modern pharmaceutical development paradigm of science-based, data-driven decision making.
