Calculator for calculating the amount of peptides in a syringe

In this case, a formula is used that relates the amount of peptide, the volume of water, the volume of the syringe, and the number of divisions on the syringe. The formula looks like this:

Syringe mark = (Required amount of peptide / Total weight of peptide) × Water volume ×100 Syringe mark = (Total weight of peptide Required amount of peptide) × Water volume×100

Where:

  • Required amount of peptide — the amount of peptide that you want to receive in a dose (for example, 0.25 mg).
  • Total peptide weight — the total amount of peptide in the vial (for example, 5 mg).
  • Volume of water — the volume of bacteriostatic water added for dissolution (for example, 2 ml).
  • 100 — the number of divisions on the syringe (for a 1 ml syringe).

Calculation example:

  • Total peptide weight: 5 mg.
  • Water volume: 2 ml.
  • Required amount of peptide: 0.25 mg.
  • Syringe: 1 ml (100 divisions).

Mark on the syringe=(0.25 mg5 mg)×2 ml×100=10 marks Mark on the syringe=(5 mg0. 25 mg)×2 ml×100=10 marks


Step-by-step explanation:

  1. Concentration of the peptide in solution:Concentration=Total peptide weight Water volume=5 mg2 ml=2.5 mg / mlconcentration=Water volumetotal peptide weight=2ml5mg=2.5 mg / ml
  2. Volume of solution for the desired dose:Volume=Required amount of peptidaconcentration=0.25 mg2. 5 mg / ml=0.1 ml Volume=Concentration of Rainbow amount of peptide=2.5 mg / ml0. 25mg=0.1 ml
  3. Converting volume to syringe divisions:Mark on the syringe=0.1 ml × 100=10 marks Mark on the syringe=0.1 ml×100=10 marks

Result:

The formula used on the site allows you to calculate up to what mark on the syringe you need to collect the solution in order to get the right amount of peptide. In your example, for a dose of 0.25 mg, you need to dial the solution to mark 10 on a 1 ml syringe (100 divisions).
