Peptide calculator
Free lab calculators for peptide solutions: concentration after reconstitution, dilution (C₁·V₁ = C₂·V₂) and molarity with the molar masses of 80 substances.
Concentration calculator (in vitro)
Stock solution: 5 mg/ml = 5 µg/µl = 5,000 µg/ml
Dilution (C₁·V₁ = C₂·V₂)
Required volume of stock solution: 200 µl (0.2 ml)
Calculation aid for laboratory solutions. No dosing information.
Molarity calculator
Molar mass (g/mol)1,419.5
- Molar concentration
- 3.52 mmol/l
- Molecules per µl
- 2,120,000,000,000,000
Molar mass from PubChem or the sequence. Calculation aid for laboratory solutions, no dosing information.
Storage at a glance
Every product page states its storage class. The range uses these three:
- Lyophilisate−20 °C, dry and protected from light; 2–8 °C after reconstitution
- Capsules, tablets15–25 °C, dry
- Solutions15–25 °C, 2–8 °C once opened
Compare substances
Structure, molar mass, research area and price per mg side by side.
Embed or link the calculator
The concentration calculator can be embedded free of charge in lab wikis, course pages or blogs. Copy the code; the calculator stays up to date automatically.
