Peptide reconstitution glossary
This peptide reconstitution glossary explains the words you'll see on vials, on insulin syringes and in the peptide calculator. Each term links to related terms.
Terms in this peptide reconstitution glossary
- Bacteriostatic water
- Sterile water with 0.9% benzyl alcohol added to slow the growth of bacteria. It is used for vials that will be opened more than once.See also: Sterile water, Benzyl alcohol, Reconstitution
- Barrel
- The clear tube of a syringe that holds the liquid and carries the printed scale.See also: Plunger, Graduation marks
- Benzyl alcohol
- A preservative added to bacteriostatic water at 0.9%. It slows the growth of bacteria in a vial that is opened more than once.See also: Bacteriostatic water
- Concentration
- How much of a substance is in each mL of liquid, usually written in mcg per mL. A 5 mg vial mixed with 2 mL of water holds 2,500 mcg per mL.See also: Reconstitution, Microgram (mcg), Milliliter (mL)
- Dead space
- Liquid left in the needle and hub after the plunger is pushed all the way in. Insulin syringes with a fixed needle have very little.See also: Insulin syringe
- Diluent
- The liquid used to dissolve a powder, such as bacteriostatic water.See also: Reconstitution, Bacteriostatic water
- Dose
- The amount of a substance taken at one time, written in mcg or mg. This site does not suggest doses; it converts a dose you enter into units.See also: Concentration
- Graduation marks
- The printed lines on a syringe barrel. On a 1 mL U-100 syringe there is a line every 2 units, and on a 0.3 mL U-100 syringe there is often one every half unit.See also: Insulin syringe, Barrel
- Insulin syringe
- A small syringe marked in units instead of mL, usually with a fine needle attached. Common sizes are 0.3 mL, 0.5 mL and 1 mL.See also: Unit (syringe), Graduation marks
- Lyophilized powder
- A freeze-dried powder. Products supplied this way must be reconstituted with a liquid before they can be measured.See also: Reconstitution, Vial
- Microgram (mcg)
- One millionth of a gram, also written µg. 1,000 mcg make 1 mg.See also: Milligram (mg)
- Milligram (mg)
- One thousandth of a gram. 1 mg equals 1,000 mcg.See also: Microgram (mcg)
- Milliliter (mL)
- A unit of volume, one thousandth of a liter. Insulin syringes usually hold 0.3 mL, 0.5 mL or 1 mL.See also: Unit (syringe)
- Plunger
- The rod you pull or push to move liquid into or out of a syringe. The rubber stopper on its end shows how much you drew.See also: Rubber stopper, Barrel
- Reconstitution
- Adding a measured amount of liquid to a powder in a vial so it dissolves into a solution you can measure with a syringe.See also: Diluent, Lyophilized powder, Concentration
- Rubber stopper
- The rubber tip on the end of the plunger. Read the amount at its flat top edge, not at the pointed tip.See also: Plunger
- Sterile water
- Water that has been sterilized and has no preservative. An opened vial of it is meant for one use only.See also: Bacteriostatic water, Diluent
- U-100 syringe
- An insulin syringe where U-100 means 100 units fill 1 mL. It is the most common type.See also: U-50 syringe, U-40 syringe, Unit (syringe)
- U-40 syringe
- An insulin syringe where U-40 means 40 units fill 1 mL. It is mostly used for veterinary insulin.See also: U-100 syringe, U-50 syringe
- U-50 syringe
- An insulin syringe where U-50 means 50 units fill 1 mL, so each unit is twice the volume of a U-100 unit.See also: U-100 syringe, U-40 syringe
- Unit (syringe)
- A mark on an insulin syringe that stands for a fixed volume, not a weight. On a U-100 syringe each unit is 0.01 mL.See also: U-100 syringe, Milliliter (mL)
- Vial
- A small glass container sealed with a rubber top that a needle can pass through.See also: Lyophilized powder
