Overview
The XPR Powder Dosing System uses a Universal Robot arm to pick Mettler Toledo powder hoppers from the 56 position carousel and place to the XPR 6 place balance. Up to 6 different vial types can be loaded into the system at any one time. The system picks the corresponding vial adaptor for each vial type before picking the vial from the SBS format rack and placing to the XPR. The powder dispensing is fully controlled by the Mettler Toledo XPR. A user can pause the run at any time to access the racks and consumables. The system will scan for new hoppers and continue the run from the previous process. The system is enclosed in an IP2X enclosure with HEPA extraction. The extraction is designed to maintain a minimum face velocity of 0.5m/s regardless of sash opening. Sash’s are mechanically interlocked to safely isolate the system in case of an emergency.
This system is based around Labman’s MultiDose™ Benchtop platform. The Automated XPR Powder Dosing System was developed as a custom variation of MultiDose for GSK. An additional HEPA air filtration module was required. The MultiDose platform has been integrated into a standalone system with an enclosure around it for safety. This system was delivered to GSK’s R&D site, Stevenage in late 2021.
