Mixing, Blending & Industrial Batch Processing calculator
Viscosity Adjustment From Lab Trial Calculator
Scale an additive quantity that already reached the viscosity specification in a matched laboratory trial. Enter the original laboratory sample, successful addition, and original production batch masses.
What this calculator does
- Scale a successful laboratory viscosity-adjustment addition to your original production batch mass.
Formula used
- Scaled addition = production base mass × laboratory additive mass ÷ laboratory base mass
- Dose per original base = laboratory additive mass ÷ laboratory base mass × 100
- Adjusted batch mass = production base mass + scaled addition
Inputs explained
- Original Laboratory Base Mass: Sample mass before the successful laboratory adjustment addition.
- Successful Laboratory Additive Mass: Measured addition that reached specification in the matched laboratory trial.
- Original Production Base Mass: Production mass before adding this adjustment ingredient.
How to use the result
- Best suited to verified solvent-cut transfer, qualified thickener trial transfer.
- Scale-up can change mixing and equilibration; the laboratory endpoint must be rechecked in production. This does not infer an additive dose from current and target viscosity alone.
Common questions
- Can I enter current and target viscosity instead? No. Those two values do not determine a universal additive quantity. First establish a successful dose using a representative laboratory sample.
- Can this scale a thickener addition? Yes, if the same thickener trial reached specification with matching composition, hydration, equilibration, and measurement conditions. Production verification remains necessary.
- Why use the original sample mass? It preserves the measured additive-to-base ratio. Using the adjusted sample mass would understate the dose for an unadjusted production batch.
- Can I add the entire result immediately? Follow your approved staged adjustment procedure. Mixing, temperature, shear history, and equilibration can make the production viscosity differ from the laboratory result.
