TOOLLINKS LAB
Solution Preparation Calculator
Find the solute mass needed for a target molarity and final solution volume, with explicit molar mass and purity correction.
TOOLLINKS LAB
Dilution Calculator — C₁V₁ = C₂V₂
Calculate the volume of stock required for a lower target concentration, with independent concentration units and a final-volume check.
TOOLLINKS LAB
Serial Dilution Calculator
Generate a dilution series with each step’s concentration, transfer volume, and nominal diluent volume. Copy the resulting table.
TOOLLINKS LAB
Percent Weight/Volume Solution Calculator
Calculate grams of solute for a percent w/v solution and a final volume. Distinguish mass/volume percent from mass percent.
TOOLLINKS LAB
Hemocytometer Cell Count Calculator
Convert counts from large hemocytometer squares into cells/mL using the observed count, squares counted, and dilution factor.
TOOLLINKS LAB
Centrifuge RCF ↔ RPM Calculator
Convert centrifuge speed between RPM and relative centrifugal force (× g) using the rotor radius in centimeters.
TOOLLINKS LAB
