The phrase "a specified volume of" is correct and usable in written English.
It can be used when referring to a particular amount or quantity of a substance or material in contexts such as science, cooking, or measurements.
Example: "To prepare the solution, add a specified volume of water to the mixture."
Alternatives: "a defined amount of" or "a designated quantity of".
Further, a specified volume of any gas (at low pressure) contains the same number of molecules as the same volume of any other gas at the same temperature and pressure.
Silicic acid release from the dots was measured by placing the nanoflakes into a specified volume of PBS and fitting a screw-cap to ensure the volume was sealed.
The aqueous solution of divalent mercury was prepared by diluting a specified volume of a mercury nitrate volumetric standard, 0.05 N aqueous solution (Sigma-Aldrich, Bornem, Belgium), in distilled water.
Comparing data with other studies is difficult particularly for root length and root biomass as many studies do not fully excavate the root system, choosing instead to excavate a specified volume of soil around the stem that leaves a proportion of roots remaining in the soil.
Usually, recommendations are expressed as the requirement to either undertake a certain amount of physical activity above specific intensity thresholds (e.g., time engaged in moderate intensity activity on a certain number of days per week) or to undertake a specified volume of physical activity (e.g., overall physical activity energy expenditure).
To this Tween solution, a specified volume of 25 mM stock CAP was added to achieve the desired concentration of CAP.
The material topology optimization method evaluates an optimal layout reinforcing or arranging material of a specified volume in a given design space that maximizes stiffness for a given set of loads and boundary conditions.
The inclusion of a specified volume percent over a limited size range (e.g., 1 nm–10 μm) and/or a total volume cutoff filter (e.g., a qualifying threshold or dust threshold) would largely enhance the identification of potential materials of interest and may also serve to simplify the associated metrology by enabling the application of more traditional metrology methods.
Moreover, for NT metals with a specified volume, reducing TB spacing is equivalent to increasing the density of TBs, which imposes a stronger resistance against lattice slipping.
The specified volume of serum was dispensed onto the RDT by micropipette.
