Mixing Syringes 21G (5-pack)

Because these syringes are accessories for liquid transfer, safety concerns revolve entirely around contamination and handling errors. The most severe risk to your research is cross-contamination. If you use the same syringe to reconstitute multiple peptide vials, or if you draw from a bacteriostatic water vial with a previously used needle, you will introduce bacteria and foreign peptides into your sterile supplies. This destroys the integrity of your samples. Another common handling error is applying too much pressure to the plunger during water transfer. Forcing the liquid rapidly into the peptide vial creates foam and turbulence, which can mechanically shear and denature the peptide molecules before your experiment even begins. Always depress the plunger slowly. Physical injury from accidental needlesticks is a direct risk due to the larger 21G needle. Never leave uncapped syringes on your workspace and never attempt to recap a used needle, as this is when most puncture accidents occur. Always keep a rigid sharps disposal container within arm's reach during the reconstitution process. These syringes are strictly for laboratory preparation and in vitro research.
