Filled and ready to go

Prefillable syringes are tried and tested medical products. Some 1.2 to 1.5 billion pieces are produced every year – most of them are made of glass. About 50 percent of these syringes are filled with heparin, an anticoagulant agent. Other pharmaceutical substances including vaccines and contrast media are also offered in prefillable syringes. One decisive advantage of these syringes is that they are immediately ready for use. The physician does not have to charge any (additional) syringes. This saves time – and material. And the dose of the medicine is particularly exact because the filling operation is automatic.
