Liquid filling is a major element of Aseptic Processing Technology. This presentation highlights the advantages of using Servo Peristaltic Filling for Flexibility– wide range of products and fill volumes Accuracy– better than 0.5% with Servo Compensation Disposable Technology– best suitable, minimal expense of product contact parts Lowest Contamination Risk- only peristaltic tubing contacts the product “Piggyback” System- easy and cost-effective integration into existing infrastructure Introduction to Servo Peristaltic Liquid Filling
Consistent Accuracy and Precision maintained throughout entire production with minimal set up Reduced risks of contamination with the lowest number of product contact parts that are easily exchangeable and can be disposable Eliminated dripping after fill via suck-back system Reduced splashing during fill by optimizing process parameters, such as number of nozzles, dispensing flow rate, nozzle and tubing sizes, bottom-up filling Flexibility with easy changeover to different products and fill volumes Aseptic Liquid Filling – Desired Essentials
Ability to interface with automatic SPC and PID process for 100% weight feedback Reduced risk of operator errors by utilizing exchangeable sets of fixed tooling in place of manual adjustments User-friendly operation based on simplicity and low maintenance Rugged system with long term consistency and reliability resulting in reduced downtime Easy integration with existing technologies and existing infrastructure for economical viability Aseptic Liquid Filling - Desired Essentials

Technology Base - 1994 • Incorporated in 1994 as Automated Machine Technologies, Inc. (AMT™), a manufacturer of packaging machines. • Driven by demand for cost effective, high performance Servo motion controllers • In-house Servo technology development, patents obtained Towards the end of XX century Computer Programmable Servo Systems were evolutionary breakthrough for high performance packaging machines.
CCL Industries, Toronto ON • Development of environmentally friendly aerosol system • 330 parts per minute citric acid dispensing • precision of 0.5% • Wide range of fill volumes, 0.2 ml up to 12 ml • Easy changeover and easy cleaning Original solution was urgently needed. ___________________________ While working with the new aerosol system, coincidently, an ideal product for Aseptic Liquid Filling was created.
Ciba Corning Diagnostic, Walpole MA • Pilot production for diagnostics research • High fill precision and easily programmable changeover to many different products and sizes • Easily removable product contact parts for autoclaving • Adjustable diving nozzles with bottom-up control __________________________ An answer was given to the demanding Ciba Corning needs with a two-axis servo peristaltic liquid filling machine and with a linear actuator for programmable nozzles.
Organon Technika, Durham NC • Sterile liquid filling, stoppering and screw capping integrated into one system • One system for over a hundred different products • Precise and aseptic liquid dispensing over wide range from 0.5mL to 1L • Programmable calibration and changeover ____________________ The flexibility of the Servo peristaltic pump became apparent when it was incorporated into the multifunctional monoblock system.
UDL Laboratories , Largo FL A manufacturer of Unit Dose Liquid Packs • Existing system required frequent and difficult adjustments of all 40 individual pistons • Lack of fill precision • Difficulty in cleaning piston cavities from sugar- based product • Dripping nozzles due to low surface tension • Problem meeting FDA regulations • Large project on-hold until a solution could be found _________________________________ Servo peristaltic dispenser with compensated flow characteristic was the only answer to the complex demand for filling UDL Unit Dose Liquid Packs. Simplicity of the hardware allowed to build the custom machine economically and in a timely manner, saving the multimillion-dollar project. In fiscal year 2005, UDL shipped over 800 million doses and ranked as the number one generic unit dose supplier.
bioMerieux, Durham NCA manufacturer of BacT/ALERT® blood culture bottles • Replacing glass container and 30mm stopper with new, cost-effective plastic vial with 20mm stopper for diagnostic blood culture bottles • Filling through stoppers with 12 piercing nozzles in aseptic production • Smaller stoppers require precise positioning of vials under piercing needles • Easy changeover • Increased fill precision • Reduced risk for contamination ___________________ With multi-axis capabilities, the Servo Peristaltic Pump was successfully integrated with a Servo-driven timing screw to precisely position the bottles under the needles.
bioMerieux, Durham NCServo Peristaltic Dispenser - Automatic SPC with 100% pre-fill/post-fill weight feedback
bioMerieux, Durham NCA manufacturer of BacT/ALERT® blood culture bottles Problems on the main production line: • High maintenance • Dripping nozzles • Complicated and time-consuming adjustments • Difficulties to maintain precise fill weights of +/-1% over 16 hours of continuous production cycle • Disposable Technology and high fill precision at production rates over 300 vials per minute demanded ___________________________ SOLUTION: - “Cantilever” Servo pump for Disposable Technology • Nozzle-to-nozzle equalizing system with feedback - Automatic tubing wear compensation - Increased fill precision was maintained over 16 hour runs, and need for manual calibration was eliminated - Daily maintenance was reduced from hours to only a few minutes - FDA requirements were easily met with disposable product contact parts One year later, on November 26, 2007, bioMerieux reported a 10% annual growth in the blood culture market.
