Direct quote from pennstreet folks: "No cuvette is needed with the G4, it identifies the medication in the vial" Nice try Slick, but we aren't talking about identfication, were're talking about accurately measuring drug strength. LET ME SEE YOU STATE THAT DRUG CONCENTRATION CAN BE DETERMINED IN ANY VIAL, SYRINGE OR IV BAG SIMPLY BY PLACING IT INTO THE iG4. FOR THE RECORD.
