What you’ll need

Before you begin, use EZ PREP to calculate concentration and sample volume using your COA potency and laboratory protocol.

Sanitize the vials

Remove the caps. Wipe both rubber stoppers with separate sterile alcohol pads and let them air dry. Work on a clean laboratory surface.

Draw the diluent

Draw air equal to your planned water volume into the syringe. Introduce the air into the water vial, then slowly withdraw the water. Choose the volume required by your laboratory protocol and intended concentration.

Add water to GLP-2TZ

Angle the needle toward the inside wall of the GLP-2TZ vial. Add the water slowly along the glass, avoiding a direct stream onto the powder.

Mix gently

Allow the powder to dissolve. If needed, gently roll or swirl the vial. Do not shake. Check that the solution is clear before continuing with your laboratory protocol.

Next: check your lot record.

Use the potency on your lot’s Certificate of Analysis when calculating a sample.
