How much bacteriostatic water for a 70 mg GLOW blend vial?

The amount of water does not change how much GLOW blend is in the vial; it sets the concentration. With 1 mL a 70 mg vial is 70 mg/mL, with 2 mL it is 35 mg/mL and with 3 mL it is 23.333 mg/mL. More water makes each unit weaker, so a given amount takes more units to draw.

How many mcg are in one unit of a 70 mg GLOW blend vial?

With 2 mL of water, one unit on a U-100 syringe holds 350 mcg (35,000 mcg per mL divided by 100). The table above gives the figure for other vial sizes and volumes.

GLOW blend dosage calculator

Pick a GLOW blend vial size, enter the bacteriostatic water added and, if you want, an amount per draw. The calculator gives the concentration and how many units that is on a U-100 insulin syringe. It does arithmetic only and does not suggest an amount.

U-100 syringes · 100 units = 1 mL · 1 mg = 1,000 mcg

Concentration

35 mg/mL

350 mcg per unit on a U-100 syringe · 3,500 mcg per 0.1 mL

Enter an amount per draw to see how many units it is and how many draws the vial holds.

Worked example

A 70 mg GLOW blend vial with 2 mL of bacteriostatic water is 35 mg/mL (35,000 mcg/mL). One unit on a U-100 syringe is 0.01 mL, so each unit holds 350 mcg. To find how many units an amount is, divide the amount in mcg by 350.
