Excellence Titrators: Precision and Reliability

Excellence Titrators merge Swiss-engineered precision with a OneClick^™ touchscreen to provide dependable acid/base, Karl Fischer, thermometric, and complexometric titrations. The modular T5-T7-T9 platform can scale from one to eight burettes, incorporates InMotion^™ automation for high-throughput workflows, and ensures compliance with 21 CFR Part 11/EU Annex 11 through LabX^™ data management, all while effectively minimizing operator intervention and transcription errors.

• Modular precision: Easily clip on burettes, sensors, or automation modules - no need to revise existing SOPs or workflows.
• Compliance by design: Roles, electronic signatures, and audit trails comply with GMP and FDA requirements.
• Hands-free throughput: InMotion performs loading, rinsing, and feeding of KF ovens, thereby liberating analysts.
• Future-proof platform: T7 is upgraded to T9; the system adjusts according to demand
• Smart productivity: The logic of conditions, SmartSample^™ RFID, and StatusLight^™ alerts serve to reduce human error.

Highlight

Halve Turnaround with Parallel Duplicate Titration

Video Credits: Mettler Toledo – Titration

Observe how the T9 cut reduces analysis time by 50 %: OneClick initiates synchronized titrations on duplicate samples through a dual-tower InMotion autosampler. Two burettes administer reagents concurrently, non-aqueous acid/base titrations occur at the same time, sensors perform automatic cleaning, and the subsequent set commences, effectively doubling throughput without the need for operator involvement.

Modular Scalability

• Snap-in flexibility: Add burettes, sensor boards, KF ovens, or liquid-handling modules as methods evolve
• Field upgrade path: Move from T7 to full T9 power (8 burettes + 2 boards) without replacing the base unit
• Parallel titrations: Run duplicate or independent assays side-by-side to double daily throughput

High-Throughput Automation

• InMotion capacity: Prepare a queue of up to 303 samples; the autosampler administers doses, performs rinses, dries, and autonomously restarts itself.
• Dual-tower efficiency: Concurrent duplicate titrations provide immediate confirmation of results for quality control release.
• StatusLight alerts: At-a-glance LEDs and remote notifications ensure that operators remain productive, eliminating any waiting time.

Effortless Compliance and Data Integrity

• LabXready: 21 CFR Part 11/EU Annex 11 includes audit trails, electronic signatures, and integrated locked databases.
• Role-based control: Configurable permissions, password regulations, and automated tracking of burette IDs and expiration dates address every shortcoming.
• Secure archiving: Tamper-proof results and server redundancy endure inspections for many years

Intelligent Workflow Control

• OneClick launch: Initiate any of the 150 methods directly from a customized home screen with a single tap.
• Conditions logic: Automated conditional steps facilitate intricate protocols, including method branching and reagent selection, thereby optimizing expert workflows.
• SmartSample accuracy: The utilization of wireless weight transfer along with reagent, metadata helps to eliminate transcription errors and reduce the need for rework.
