A 1 cm square cuvette accommodates 1 mL of liquid per 1 cm of height. Therefore, a 43.75 mm height (45 mm – 1.25mm base thickness) cuvette may hold up to 4.375 mL of liquid. If the cuvette is 80% full, then the total volume will be 3.5 mL, which is the so-called standard volume. 4.375 mL x 80% = 3.5 mL.
