Review the quantities needed to describe a research stock solution and calculate a laboratory sample volume.
What Reconstitution Means
Reconstitution involves dissolving a lyophilized material in a compatible solvent. Select the solvent and preparation method using the material documentation and a validated laboratory procedure.
Information and Equipment
- Documented material mass and lot identification
- A compatible solvent specified by the laboratory method
- Calibrated pipettes or other suitable volumetric equipment
- A measured final solution volume and labeled sample containers
Record the Preparation
- Review the material specifications and laboratory handling procedure.
- Record the material mass and solvent identity.
- Prepare the solution using the validated method and verify dissolution.
- Measure and record the final solution volume.
- Label the preparation with its identity, concentration, lot, date, and storage conditions.
Calculation checks
- Keep mg and µg conversions consistent: 1 mg = 1,000 µg.
- Use final solution volume, which may differ from the solvent volume added.
- Verify that the target sample mass does not exceed the total material mass.
- Record any method-specific assay, purity, or recovery corrections separately.
