We trialed a spiral plater for two weeks and the one habit that saved us headaches was a 30‑second dye run before the first batch each day to catch nozzle drift — we saw a 0.4‑log swing on day three without it… What’s your daily volume and typical CFU range with these “spiral platers”? If your lab’s recent quality control shifts mean duplicate plates for verification, the cost savings shrink fast.

Leaning yes if leased; add weekly 100 µL gravimetric check to catch drift. @Guide sync to LIMS for ‘patient data’?

From our numbers, it’s only “worth the cost” if you’re pushing about 80+ plates/day; below that, the service contract and consumables eat the gain. Quick step: run a 2‑week side‑by‑side (≥50 samples) and accept slope 0.95–1.05 vs manual counts, then lock method params in LIMS so QC shifts don’t creep into patient data. @Guide have you seen drift when folks tweak speed/volume mid‑run, and what’s your daily throughput/SLA?
