SCHOTT Pharma has pre-validated its ISO-standardised TOPPAC polymer cartridge for compatibility with SHL Medical’s large-volume Maggie autoinjector platform. The collaboration delivers a de-risked, ready-to-use solution for the safe at-home administration of large-volume therapies

SCHOTT Pharma has continued its collaboration with SHL Medical and pre-validated the ISO-standardised polymer cartridge with SHL Medical’s large-volume autoinjector platform.

The SCHOTT TOPPAC polymer cartridge is the first in SCHOTT Pharma’s polymer product portfolio to meet both ISO dimensions and the global RTU standard, SCHOTT iQ.

The system developed by SCHOTT Pharma and pre-validated for compatibility with SHL Medical will be showcased at Pharmapack Paris, January 21-22 (Hall 4, booth G38).


Polymer solutions come into play when medications have special requirements, such as low silicone levels or deep-temperature storage, for example.

The polymer cartridges are suitable for safely storing and administering highly sensitive biologics, including cell and gene therapies, biosimilars and emergency medications.


"Thanks to our collaboration with SHL Medical, we’ve taken a big step forward in offering a complete solution to pharma companies," said Andreas Reisse, CEO of SCHOTT Pharma.

SCHOTT Pharma and SHL Medical conducted compatibility studies that assessed both dimensional and functional fit of the SCHOTT TOPPAC polymer cartridge with Maggie autoinjector platforms.

The joint assessment confirmed the full system compatibility. This includes the 3 ml SCHOTT TOPPAC cartridge with Maggie 3.0 ml and the 5 ml SCHOTT TOPPAC cartridge with Maggie 5.0 ml autoinjector.

This milestone enables access to a pre-validated and de-risked solution for the safe and convenient administration of large-volume medications at home, supporting self‑injection for a wide range of therapies.

As part of the SCHOTT iQ platform, the polymer cartridge is delivered in an industry-standard nest-and-tub configuration, streamlining fill-and-finish processes and helping to accelerate time to market for pharmaceutical companies.

In addition to the polymer option, SCHOTT Pharma’s 3 ml and 5 ml cartriQ glass cartridges are also compatible with the Maggie 3.0 ml and 5.0 ml autoinjectors, providing pharmaceutical companies with options for material choice tailored to the specific needs of each therapy and patient population.

Expanding compatibility with further medical devices

Building on this achievement, SCHOTT Pharma and SHL Medical are expanding their collaboration with future studies assessing the compatibility of the SCHOTT TOPPAC polymer cartridge with SHL Medical’s pen systems.

SCHOTT Pharma is also exploring opportunities to extend compatibility to additional medical devices in the future.

"Our strong partnership with SCHOTT Pharma has been instrumental in driving both productivity and innovation."

"By working hand in hand, we’re developing solutions that meet the evolving needs of patients and industry stakeholders," emphasises Markus Puusepp, Chief Growth Officer at SHL Medical.

"We are excited to continue this close collaboration, leveraging the SCHOTT TOPPAC cartridge alongside our advanced injection device systems to deliver even greater value."
