Laboratory tools
Bench tools
A set of calculators for laboratory measurement and record-keeping. Each one performs arithmetic on the figures you enter — nothing is recommended, assumed, or suggested.
Concentration calculator
Enter any three quantities and the fourth is derived. Every figure is a unit conversion performed on the values you supply — nothing is recommended, assumed, or suggested.
Blend calculator
A blend vial holds several compounds in a fixed ratio, so every draw carries all of them proportionally. Pick a blend from our catalog for its published ratio, or enter a composition of your own.
Dilution calculator
Start from a solution that already has a concentration and make it weaker by adding diluent. Enter any three of the four quantities and the fourth is derived from them.
Unit converter
Convert between units of mass, volume and concentration. International Units resolve only when you supply the compound's units-per-milligram — that ratio is defined per substance and is never assumed here.
Molarity converter
Convert between mass and molar concentration. Enter the compound's molecular weight plus any two of mass, volume and concentration — the third is derived.
Research use only
These tools perform arithmetic on figures entered by the operator. They are provided for laboratory measurement and record-keeping in non-clinical research settings. Biopunk supplies research-grade compounds for laboratory and non-clinical research use only. All compounds are For Research Use Only and are not intended for human or animal consumption. Nothing here constitutes guidance on preparation or administration.
