Aqueous Size Exclusion Chromatography with MALLS detection (Freddie)
State of the art chromatography system including autosampler, column oven, UV-Vis, RI, and multi angle light scattering (MALLS) detection. The stationary phase are 300 × 8 mm2 PSS NOVEMA Max columns running on an eluent of aqueous 0.1 M NaCl including 0.3 vol % formic acid at a flow rate of 1 mL min–1. The system is ideally suited to measure size distributions of cationic (co)polymers over a large range of molecular weights. The device has its name from Freddie Mercury because of the flamboyant way it moves its sample gripper.

Photoreactor - PhotoCube™ by ThalesNano (Luigi)
High power LED-based photo reactor with 7 avilable irradiation wavelengths (365 nm, 395 nm, 457 nm, 500 nm, 523 nm, 595 nm, 623 nm, and a white light mixture) with powers up to 128 W per color (measured Intensity ~ 400 mW cm-2 for blue light at sample position at highest power). The reactor has active (air) cooling and fits up to 8 vials or one flask (50 mL RBF). Power output can be modulated and up to 3 colors can be used at the same time. The device has its name from Giacomo Luigi Ciamician, a (the?) pioneer of photochemistry.

3D-Printers (Alexa & Bob)
Asiga Max UV 27 um (Alexa, red hood) and Anycubic Photon D2 (Bob, blue hood) incl. postcuring/cleaning station by Anycubic (yellow hood). Both are DLP printers for open material vat polymerisation using 385 nm and 405 nm, respectively. Alexa has a voxel of 27x27x5 um³ and is used fro research, while Bob has a voxel of 50x50x50 um³ and is mainly used for outreach and applications.
Alexa is named after her place of birth (Alexandria, NSW, Australia). Bob is named after Bob the Builder referring to his use in teaching.
