¹Prices based on 500 g reagent grade chemicals from Fisher Scientific.

²Bulk scale prices based on 50 kg reagent grade chemicals from Fisher Scientific, when available. Otherwise, price based on largest reagent grade size available (1-10 kg). Bulk scale pricing was not taken into account for trace materials.

³Bulk discounts not available.

⁴Commodity scale replaces (mass for mass) glucose with corn syrup, nitrogen sources with corn steep liquor, and eliminates trace metals.
