Abstract
An advanced analytical chemistry undergraduate laboratory module on microfluidics that spans 4 weeks (4 h per week) is presented. The laboratory module focuses on comprehensive experiential learning of microfluidic device fabrication and the core characteristics of microfluidic devices as they pertain to fluid flow and the manipulation of samples. Experiments include the cleanroom-free fabrication of glass-polydimethylsiloxane (PDMS) microfluidic devices by use of thermoplastic molds and soft lithography, determination of the zeta potential at the microchannel walls, investigations of electroosmotic flow, determination of Péclet numbers, and diffusion coefficients based on diffusion-limited reagent mixing. The module concludes with the development of a microchannel electrophoresis lab-on-a-chip device with in-line fluorimetric detection for the separation of a DNA ladder. This laboratory module has been offered for two consecutive years and has received favorable student feedback.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
