Our lyophilized peptides are vacuum-sealed, which can sometimes make extraction a bit challenging. To make this easier, simply inject a small amount of air into the vial before drawing the solution. This relieves the vacuum pressure and allows for smoother withdrawal.

The presence or absence of strong vacuum pressure does not indicate anything about the sterility of the product. Some vials may have enough negative pressure to pull the plunger down, while others may not — both are normal and do not affect the sterility or quality of the contents.
