Market taxonomy for Types is shaped by surface chemistry and geometry, not by brand. Petri-Style Dishes remain the workhorse, available in 35 mm, 60 mm and 100 mm footprints; untreated versions serve suspension cultures, while TC-treated or collagen-coated variants capture adherent lines, letting suppliers extract a 2-4× price multiplier. Multiwell Dishes—6-, 12- and 24-well formats cast from the same polystyrene resin—reduce plastic per data point and dominate early-stage cytotoxicity work, accounting for ~30 % of unit sales. Specialty Dishes (low-attachment, micro-patterned, or embedded electrode grids) constitute <10 % of volume but >25 % of value, as they enable spheroid, organoid and impedance assays that standard plates cannot perform. Finally, Large-Area/Stackable Dishes (150 mm and 3-layer “triple dishes”) address harvest-scale needs for exosome or viral vector production; adoption is cyclical, tied to CGMP campaigns, so ASP erosion is minimal once validated.
