Our reconstitution calculator is designed to make things quick, easy, and less confusing. It helps you work out how strong your vial is after mixing, how much to draw up for each dose, and how many doses are in the vial.

Step 1: Enter the medication in the vial

In the “Medication in vial” box, type the total amount that was originally in your vial before adding bacteriostatic water.

Example:
If your vial says 10mg, enter 10.

Then choose the correct unit:

• mg if your vial is labelled in milligrams (most common)

• mcg if your vial is labelled in micrograms
  
  

Step 2: Enter how much bacteriostatic water you added

In the “Bacteriostatic Water Added” box, enter the total amount of water you mixed into the vial.

Example:
If you added 2mL of bac water, enter 2.

This is important because the calculator uses this to work out the final concentration.

Step 3: Enter your desired dose per injection

In the “Desired dose per injection” box, enter the amount you want to take each time.

Example:
If your dose is 1mg per injection, enter 1.

This tells the calculator what single dose amount you want it to convert into syringe volume and units.

Step 4: Choose your insulin syringe scale

Under “Insulin syringe scale”, choose the syringe type you are using.

Most customers will use:

• 100 units = 1mL (U-100)

All syringes provided by Illuminate Life will be 100 units (1ml). Only change this if you are using a different syringe type that you have purchased elsewhere. 

Step 5: Press Calculate

Click the Calculate button and the calculator will instantly show you your results.

Concentration

This shows how strong the mixed vial is after reconstitution, usually in mg per mL.

In simple terms, it tells you how much medication is in each 1mL of liquid. Adding more or less bac water will change the concentration. 

Volume for Dose

This tells you exactly how much liquid to draw up for your chosen dose.

It shows:

• the amount in mL

• and the matching syringe units
  
  

This is usually the most important result for customers using insulin syringes.

Vial Coverage

This tells you approximately how many doses are in the vial at the dose you entered.

Example:
If it says 10, that means your vial contains about 10 injections at that dose. Keep in mind that this assumes accurate dosing. If you accidentally take too much each dose, then this will add up over time and your last dose might appear like you're a little short. Be careful and accurate when drawing up each dose, as even 1 additional unit at a time will add up.
