Reconstitution Basics for the Lab

Most research peptides ship as a lyophilised (freeze-dried) powder for stability. Before use in the lab, they are reconstituted with a suitable diluent — commonly bacteriostatic water.

Concentration is simple arithmetic

The concentration of a reconstituted vial is the amount of compound divided by the volume of water added. For example, a 10 mg vial reconstituted with 2 mL of water gives a concentration of 5 mg/mL.

Working out the volume to draw

Once you know the concentration, the volume to draw for a given amount is that amount divided by the concentration. Our Reconstitution Calculator does this for you and shows the equivalent units on a U100 syringe.

Handling and storage

Store lyophilised material as indicated on each product page — typically frozen and protected from light — and refrigerate reconstituted solution. This guidance is for laboratory handling of research materials only.
