Schott’s rigid caps add a new twist to prefilled syringes

Closure systems for glass and polymer syringes are said to improve patient safety while securing packaging supply chain

TopPac Rigid Cap (TRC), a new closure system for prefilled polymer syringes

German pharmaceutical glass manufacturer Schott has added new closure systems to its portfolio of prefillable syringes (PFS), which it says offer more flexibility for pharma companies while keeping patients safe.

syriQ Rigid Cap (SRC) and TopPac Rigid Cap (TRC) feature an intuitive twist-off mechanism. The caps ensure the integrity of the container, yet can easily be opened. They offer a seamless fit for Schott’s syriQ series of prefilled glass syringes, and its polymer equivalent TopPac. SRC is available from this month, with TRC to follow later in the year.

'Container closure integrity (CCI) is one major concern in the pharma industry. Another is usability. Our new closure systems deliver in both areas,' said Anil Busimi, the head of product management syringes at Schott Pharmaceutical Systems.

'The design of SRC, our solution for syriQ glass PFS, matches a closure system the industry is already familiar with. This adds a great deal of flexibility to our customer’s supply chain, and it speeds up time to market for new or already existing drug products.'

SRC combines a rubber tip cap with a rigid cap screwed in a Luer Lock adapter.

The closure system is supplied pre-assembled with Schott's glass syringe barrels, all pre-sterilised and in a standard nest and tub configuration.

TRC is a rigid cap for the Schott TopPac polymer PFS portfolio. The rigid cap, fitted with a rubber tip cap and twist-off mechanism, is easy to open and connect with hypodermic needles, IV connectors, or vial adapters, and reduces the risk of contamination while opening the closure system.
