Lab math reference

Research calculator

Educational lab-math for concentration, draw volume, and U-100 syringe units from vial mass and solvent volume. Research handling reference only — not medical advice, dosing protocols, or personal-use guidance.

I understand this tool is for research lab-math and educational reference only. It is not medical advice, dosing guidance, or personal-use instructions.Required before using the calculator

Enter vial mass, solvent (BAC or sterile water) volume, and a target aliquot mass. Returns concentration, draw volume in mL, and U-100 syringe units — forward lab-math from known reconstitution volume.

Common lab dilution examples

Generic examples keyed by vial mass only (10, 20, 50, and 60 mg). These illustrate concentration and U-100 unit arithmetic for laboratory worksheets — not protocols, schedules, or personal-use guidance.

10 mg vial

Illustrative concentration arithmetic when a 10 mg lyophilised vial is reconstituted with common solvent volumes. Educational lab-math only — not a protocol.

Water	Concentration	Example mass	U-100
1 mL	10,000 mcg/mL	250 mcg	2.5 units
2 mL	5,000 mcg/mL	250 mcg	5 units
3 mL	3,333.33 mcg/mL	250 mcg	7.5 units

20 mg vial

Illustrative concentration arithmetic for a 20 mg lyophilised vial. Solvent volume and target aliquot mass determine draw volume on a U-100 scale.

Water	Concentration	Example mass	U-100
1 mL	20,000 mcg/mL	500 mcg	2.5 units
2 mL	10,000 mcg/mL	500 mcg	5 units
3 mL	6,666.67 mcg/mL	500 mcg	7.5 units

50 mg vial

Illustrative concentration arithmetic for a 50 mg lyophilised vial. Values are educational examples for stock-solution maths, not handling instructions.

Water	Concentration	Example mass	U-100
1 mL	50,000 mcg/mL	1,000 mcg	2 units
2 mL	25,000 mcg/mL	1,000 mcg	4 units
3 mL	16,666.67 mcg/mL	1,000 mcg	6 units

60 mg vial

Illustrative concentration arithmetic for a 60 mg lyophilised vial. Adjust solvent volume in the calculator to match your laboratory worksheet.

Water	Concentration	Example mass	U-100
1 mL	60,000 mcg/mL	1,000 mcg	1.67 units
2 mL	30,000 mcg/mL	1,000 mcg	3.33 units
3 mL	20,000 mcg/mL	1,000 mcg	5 units

Lab-math glossary

mg (milligram): One thousandth of a gram. Catalogue vial strengths are typically listed in mg of lyophilised peptide mass.
mcg (microgram): One thousandth of a milligram (1 mg = 1,000 mcg). Aliquot and concentration maths in this tool use mcg for finer resolution.
Syringe units (U-100): On a U-100 insulin-style syringe, 100 units equal 1 mL. Draw volume in mL × 100 ≈ syringe units marked on the barrel.
IU (international unit): Activity-based units used for some biologics. Not used for current The Protocol catalogue strengths — this calculator works in mass (mg/mcg) and volume (mL/units) only.
