Sample Changer

Sample changers are automated accessories used with titration systems to enable unattended, sequential analysis of multiple samples, significantly increasing laboratory throughput compared to manual, one-sample-at-a-time titration. These devices typically consist of a carousel or rack that holds a series of sample vessels, along with robotics that position each sample under the titrator's electrode and dosing unit in turn, automatically rinsing between samples to prevent cross-contamination. Many sample changers integrate directly with titration software, allowing users to program batch sequences, assign specific titration methods to individual samples, and review results across an entire run. Automated sample changers are widely used in quality control and research laboratories across the pharmaceutical, food and beverage, petrochemical, and environmental testing... + More

Sample changers are automated accessories used with titration systems to enable unattended, sequential analysis of multiple samples, significantly increasing laboratory throughput compared to manual, one-sample-at-a-time titration. These devices typically consist of a carousel or rack that holds a series of sample vessels, along with robotics that position each sample under the titrator's electrode and dosing unit in turn, automatically rinsing between samples to prevent cross-contamination. Many sample changers integrate directly with titration software, allowing users to program batch sequences, assign specific titration methods to individual samples, and review results across an entire run. Automated sample changers are widely used in quality control and research laboratories across the pharmaceutical, food and beverage, petrochemical, and environmental testing industries, where large numbers of samples must be titrated consistently for parameters such as acidity, moisture content, or ion concentration. By automating repetitive titration tasks, sample changers free up analyst time for other work while improving the reproducibility of results. Manufacturers such as Metrohm, Mettler Toledo, and Hanna Instruments offer sample changer accessories designed to integrate with their titration platforms, helping labs scale up titration throughput without sacrificing accuracy. ALT carries a wide selection of pre-owned, refurbished titrator sample changers. Every unit includes a standard 90-day warranty, with the option to upgrade to a three-year warranty, plus ALT's lifetime support for as long as you own the equipment. Refurbished titrator sample changers from ALT typically cost 50%-80% less than buying new, making it easier for labs to get the equipment they need without straining their budget. - Less
