The phrase "adjusted to a density" is correct and usable in written English.
It can be used in contexts where something is modified or calibrated to achieve a specific density, often in scientific or technical discussions.
Example: "The solution was adjusted to a density of 1.2 grams per cubic centimeter to ensure optimal performance."
Alternatives: "modified to a density" or "calibrated to a density".
The cells were adjusted to a density of 2.5×105 cells/cm2 and were cultured at 37 °C in 95%air/5%% CO2.
The protoplasts were adjusted to a density of 1.5-2 x 107 cells/ml (Kyozuka et al 1987).
The volume of the bacterial suspension is then adjusted to a density of 1012 cells/ml (assuming that an OD650 of 0.1 corresponds to 108 cells/ml).
The soil was then adjusted to a density of 1.3 g cm−3 and a soil water tension of −15 kPa [34].
The pooled infranatants were adjusted to a density of 1.21 g/ml and re-centrifuged at 250,000 g for 24 36 h at 10°C.
PBMC were then washed in RPMI medium, adjusted to a density of 1×106 cells/mL, and cultured in 24-well flat-bottom culture plates.
The soil was re-adjusted to a density of 1.3 g cm−3, moistened to a soil water tension of −15 kPa, and incubated in the dark at 20 ± 1 °C for another 49 days.
Conidia were harvested as described in De Vleesschauwer et al. [ 28], and inoculum concentration was adjusted to a final density of 1 × 104 spores ml-1 in 0.5% gelatin (type B from Bovine skin; Sigma-Aldrich G-6650).
Bacterial strains were grown to exponential phase in nutrient broth at 37°C for 18 h and adjusted to a final density of 108 cfu/ml by diluting fresh cultures and comparison to McFarland density.
The cell density of the suspensions was estimated by direct cell count using a Thoma camera, and adjusted to a cell density ranging from 0.5 × 103 to 2.5 × 103 cfu/mL (twice the final inoculum size); 50 μL was added to each well of the micro-dilution plate, followed by incubation for 48 hr at 35 C°.
Thus, test strains adjusted to a final density of 1.0 × 107 CFU/ml were not growth inhibited even in the presence of 25% of S-PRG eluate after 18-h incubation at 37 °C and were mainly used in subsequent studies.
