Core Principles

Precision and sterility in the lab

Maintaining aseptic conditions and avoiding structural damage to peptide chains are critical.

Work slowly, keep the stopper surfaces clean, and measure each transfer deliberately. The goal is controlled preparation: clean entry, stable pressure, gentle side-wall flow, and a fully dissolved solution before any final draw is measured.

Before you begin, confirm the exact amount of diluent you plan to add so you can pair this visual guide with the reconstitution calculator.

Procedure

Reconstitution workflow

Follow these steps in order to equalize pressure and transfer bacteriostatic water safely.

Prep
BAC WATERALCOHOL
01

Sanitize Diluent Vial

Thoroughly wipe the rubber stopper of the diluent vial with a sterile alcohol pad.

Prep
PEPTIDEALCOHOL
02

Sanitize Peptide Vial

Sanitize the red rubber stopper of the Peptide vial. Use a fresh pad or a clean side of the existing pad.

Measure
03

Draw Air into Syringe

Pull the plunger back to the desired volume. This air will be used to equalize pressure in the BAC water vial.

You can determine the desired volume with the reconstitution calculator.

Balance
BAC WATER
04

Equalize Pressure

Insert the needle into the BAC water vial and inject the air. You may see bubbles as the pressure equalizes.

Draw
BAC WATER
05

Draw Liquid

Invert the vial and syringe. Pull back the plunger to draw the exact volume of water needed for your reconstitution.

Transfer
PEPTIDE
06

Inject Slowly

Angle the needle against the side wall of the peptide vial. Flow the water gently down the glass to avoid disturbing the powder directly.

Dissolve
PEPTIDE
07

Swirl to Dissolve

Gently swirl the vial in a circular motion. Continue until the solution is clear and all powder has dissolved. Do not shake.

Final Draw
PEPTIDE
08

Draw Final Solution

Invert the reconstituted vial and use an insulin syringe to draw the exact amount required for your laboratory protocol.

You can calculate the exact amount to draw with the reconstitution calculator.

Critical Reminders

Handling and lab notes

Key observations to maintain peptide integrity and ensure accurate dosing during the transfer process.

Stopper Sanitization

Always wipe both rubber stoppers with a fresh alcohol pad. Allow them to air dry for 30 seconds to ensure a sterile entry point.

Pressure Equalization

Injecting air into the BAC water vial first prevents a vacuum, making it significantly easier and more accurate to draw the liquid.

Gentle Dissolution

Never shake the vial. Peptides are fragile; always inject down the side wall and swirl gently to avoid foaming or chain shearing.

Preparation Syringe Only

The syringe used to draw and transfer diluent is part of the reconstitution setup and should not be reused for injection.
