TECH OUTLOOKTECH OUTLOOKNOVEMBER 202319 As trailblazers in the field, Tempris collaborated with a partner to create an automated robot solution, ensuring comprehensive traceability by consistently placing sensors in critical positions. This facilitates batch-to-batch comparability across different freeze dryers. Tempris has tailored its software to align with customer needs, providing qualification documentation in compliance with pharmaceutical regulations.Tempris System Components: A Holistic OverviewThe Tempris system comprises temperature probes situated within vials or other product containers, an array of antennas within the lyophilizer, an interrogation unit connected to the antennas via cables, and a computer linked to the interrogation unit.At the core of each Tempris probe lies a meticulously shaped and mounted quartz crystal. These crystals exhibit the piezoelectric property, causing them to oscillate in response to the applied voltage, with the frequency of oscillation dependent on the temperature. Once the excitation energy ceases, the piezoelectric property prompts the crystal to generate an electric field, empowering each probe to transmit a return broadcast encoded with temperature information.Optimal antenna placement within the lyophilizer facilitates the transmission of the excitation signal to the probes and the reception of the return signals multiple times per second. This allows for the digitalization of product temperature data, enabling comparison and improvement processes.The Gold Standard in Temperature Measurement"Tempris technology with battery-free and wireless sensors is the gold standard in temperature measurement during lyophilization. With compliance to 21CFR Part 11 (FDA) and GAMP 5 (EMA) regulations, it ensures full data integrity for GMP applications. Its accurate measurement process, free from heat input, and real-time transmission of data make it one of the most reliable methods available," says Jim Searles, Ph.D., technical advisor, and representative.A contract manufacturer in Europe, producing a global company's lyophilized product, has successfully employed Tempris sensors in over 160 batches. Embracing the continuous process verification (CPV) approach, they have not lost a single batch due to lyophilization issues, crediting the reliability of Tempris data in ensuring acceptable product temperatures during deviations. This remarkable performance has allowed the customer to include Tempris data evaluations in regulatory filings, securing regulatory flexibility for process modifications and equipment changes. The commitment to continuous data evaluation has granted them the freedom to adapt their process for different batch sizes, cycle modifications, and equipment transitions across multiple global markets.Team Dynamics and Global CollaborationsThe company has around 30 members and organizes its operations into separate teams for sales and service. Tempris is ISO qualified, conducts in-house manufacturing, and serves clients worldwide, including the USA, Japan, Korea, Taiwan, India, and Europe with a focus on client understanding and process improvement.Tempris has established its technology across diverse industries and boasts a clientele of 20 major pharmaceutical companies, CMOs, CDMOs, and laboratories. It has successfully implemented the technology in approximately 250 projects globally, offering support for various primary packaging formats. Collaborating with ATS (formerly SP Scientific), it integrated the Tempris system into high-end development and commercial freeze dryers.Today Tempris is a revolutionary tool in the field of lyophilization for pharmaceutical applications. This is attributed to its ability to shift focus from mere validation to the continuous monitoring of critical quality attributes during lyophilization processes."With Tempris technology, we now have the capability to conduct critical quality attribute monitoring anywhere in the equipment--a crucial aspect that, until now, lacked scientific understanding. This advancement allows the user to gather comprehensive data and establish connections within the full-scale equipment, enabling our customers to enhance product quality, increase throughput, and bolster the reliability of the entire process," says Anton Mangold, CEO of Tempris GmbH.Tempris technology is a pivotal tool in simplifying the regulatory approval process, offering a streamlined approach to continuous data collection on the most critical parameter in freeze drying. By providing an in-depth understanding of the process, it facilitates a smoother regulatory approval journey for companies. "Tempris goes beyond conventional monitoring systems by offering the ability to monitor and control data across multiple freeze dryers and sites, even on an international scale. In essence, it enhances data accuracy and contributes to a more efficient and globally adaptable regulatory compliance experience for companies venturing into freeze-drying applications," concludes Dr. Hansjoerg Hufnagel, head of sales, marketing & BD. Tempris technology with battery-free and wireless sensors is the GOLD STANDARD in temperature measurement during lyophilization. With compliance to 21CFR Part 11 (FDA) and GAMP 5 (EMA) regulations, it ensures full data integrity for GMP applications and is one of the most reliable methods available
