How to Use This Calculator
This tool calculates the volume to draw from a reconstituted peptide vial based on your syringe type, vial size, bacteriostatic water volume, and target aliquot size. It is intended as a mathematical reference for laboratory research preparation only.
Step-by-Step Guide
- Syringe Volume: Select your insulin syringe capacity (0.3 mL, 0.5 mL, or 1.0 mL). This determines the unit scale shown on the syringe preview.
- Peptide Vial Strength: Select the total milligrams of peptide in your lyophilized vial. Alpha Tides compounds are available in varying vial sizes — check your product label.
- Bacteriostatic Water: Select how many milliliters of bacteriostatic water (BAC water) you are adding to the vial. The BAC water volume directly determines the resulting concentration.
- Aliquot Size: Select your target research aliquot in micrograms (mcg). The calculator outputs how many syringe units to draw and the exact mL volume.
Understanding the Results
The calculator displays four output values:
- Concentration (mg/mL): The resulting peptide concentration after reconstitution. Equal to vial strength ÷ BAC water volume.
- Solution Volume/Aliquot (mL): The exact mL volume to draw for your target aliquot.
- Aliquots/Vial: How many aliquots of your chosen size are available from the full vial.
- Units to Draw: The syringe unit marking to draw to, based on your syringe type. U-100 syringes have 100 units per mL.
Bacteriostatic Water Volume Guidance
The BAC water volume you choose affects concentration and ease of precise measurement. More water = lower concentration = larger draw volumes (easier to measure precisely). Less water = higher concentration = smaller draw volumes (harder to measure precisely, but more aliquots fit in a smaller administration volume).
For most research applications, 1–2 mL of BAC water per vial provides a workable concentration range for common aliquot sizes. See the BAC Water Ratio Chart and Draw Volume Reference Chart for detailed reference tables.
