MBraun Unilab Workstation

The MBraun Unilab Workstation is an essential resource for the Center for Photochemical Sciences, providing a strictly controlled, inert environment for the synthesis and handling of air-sensitive materials. By maintaining an atmosphere of high-purity nitrogen or argon with oxygen and moisture levels below 1 ppm, the Unilab enables researchers to push the boundaries of materials science without the interference of atmospheric contamination.

## Critical Research Benefits

• Synthesis of Air-Sensitive Catalysts: Many of the photocatalysts and organometallic complexes developed at the CPS are highly reactive toward oxygen and humidity. The Unilab allows for the safe synthesis, purification, and storage of these compounds, ensuring their chemical integrity is preserved for downstream spectroscopic studies.

• Fabrication of Organic Electronics (OLEDs & OPVs): Developing next-generation Organic Light Emitting Diodes (OLEDs) and Organic Photovoltaics (OPVs) requires the deposition of thin films that are often extremely sensitive to degradation. The glovebox serves as a "cleanroom" environment for spin-coating and assembling these devices under inert conditions.

• Battery and Energy Storage Research: For CPS projects involving lithium-ion or next-generation battery technologies, the Unilab provides the moisture-free environment necessary for handling volatile electrolytes and reactive anodes, preventing hazardous reactions and ensuring reproducible data.

• In-Situ Material Characterization: The workstation is designed to house sensitive analytical equipment, such as microbalances or specialized optical setups, allowing researchers to characterize air-sensitive samples without ever exposing them to ambient air.

## Key Technical Features

Integrated Gas Purification

Continuously removes $O_2$ and $H_2O$ to maintain sub-ppm levels.

Large Antechamber

Facilitates the rapid transfer of glassware and equipment without compromising the internal atmosphere.

PLC-M Touchscreen Control

Provides real-time monitoring of internal pressure and atmosphere quality with automated alerts.

Modular Expandability

Allows for the integration of freezers (for thermally sensitive initiators) or solvent removal traps.

## Strategic Value to the CPS

As the Center continues to modernize its facilities, the MBraun Unilab stands as a vital tool for high-impact research:

• Enhanced Safety: By providing a physical barrier and controlled pressure (positive or negative), the Unilab protects researchers from handling hazardous or pyrophoric materials.

• Reliability for Long-Term Studies: The system is designed for 24/7 operation, allowing for extended experiments—such as long-term polymerization or stability testing—to proceed under constant environmental conditions.

• Student Excellence: Mastery of glovebox techniques is a core competency for modern chemists; the Unilab ensures CPS graduates are proficient in the rigorous air-free techniques required by top-tier industrial and academic employers.

Operator Note: To maintain peak performance, please ensure that at least three vacuum/refill cycles are performed when using the antechamber and that gloves are inspected regularly for punctures.
