Ready-to-go calculator

Basic setup

Enter the vial size, diluent volume, measurement scale, and target amount. The reference volume and unit mark update automatically.

Starting point10 mg + 3 mL selected

Optional shortcut. The default starting point is 10 mg + 3 mL.

Total amount of material in the vial.

Total BAC water or diluent volume added to the vial.

Product label or research protocol comes first. Use this calculator as a reference check.

1.0 mL U-100 reference scale

0 units 0.000 mL

Use the flat edge of the black stopper closest to the tip as the measurement reference. Align that edge with the red reference line.

Common Research Handling Protocol

Research Use

Use this as a research-preparation checklist before creating an analytical stock. Lot-specific product labeling, COA files, SDS information, compatibility data, storage requirements, and institutional SOPs supersede this reference. See also Peptide Handling and Storage.

1. Verify records and calculation

Confirm material name, lot/COA, vial quantity, intended final volume, target amount or concentration, and selected measurement scale before opening the vial.

2. Equilibrate and set up

If removed from cold storage, let the unopened vial reach room temperature while sealed. Prepare a clean surface, PPE, labels, worksheet, and sterile single-use transfer supplies.

3. Confirm diluent and clean septum

Use the solvent or buffer specified by the protocol. Wipe the rubber stopper with a fresh 70% isopropyl alcohol pad, let it dry, and do not touch the cleaned septum.

4. Add diluent and dissolve gently

Direct liquid along the vial wall when possible. Let the lyophilized material wet evenly, then gently swirl or roll only as the protocol permits. Avoid foaming or unnecessary agitation.

5. Inspect, label, and store

Check clarity, residue, visible particulates, unexpected color change, or incomplete dissolution. Record material, lot, concentration, diluent, preparation date/time, storage condition, and review date.

6. Document exceptions

Log calculation changes, appearance concerns, temperature excursions, contamination concerns, or any deviation from the product protocol before use in a study workflow.

Use this when you want a chosen amount to line up with a chosen mL or U-100 mark. Enter the amount and the mark you want. The calculator returns the total diluent volume to add.

Example: with a 10 mg vial, you can ask what diluent volume would make 1 mg line up with 20 U-100 units.

Add this much diluent 0.00 mL

Based on the vial quantity above. This is the total liquid volume needed to make the chosen amount line up with the selected scale mark.
