The 400 is an economical, high-capacity autosampler specifically for automated, routine LC requirements in pharmaceutical, basic chemical, and environmental applications. Like more expensive autosamplers, it boasts a small footprint, high throughput, and rugged design—-all at a surprisingly low price.

Performance

• 96-sample capacity makes the 400 very efficient for high throughput, HPLC quality control procedures.
• Unique finger valves economize the volume of sample required for precise loop fill injections.
• A single key stroke makes it easy to start routine automated runs.
• Automatic calculation of the total and remaining run times improves laboratory efficiency.
• Four removable racks allow sample preparation while the unit is running.
• A standard electrically actuated Valco valve with easy access allows quick servicing.
• Separate wash vials assure minimal carryover for the best results.
• Optional 5 mL vials allow injection of larger sample volumes.
• An optional cooling accessory is available for critical temperature sensitive applications.

ProStar HPLC AutoSamplers

From built-in sample preparation capabilities to an integrated column oven, Varian HPLC AutoSamplers offer great performance and value.

• High-resolution syringe design for maximum reproducibility
• Extensive variety of sample tray and vial types for full flexibility
• Cooling and biocompatible options available
• Easy-access needle, injector valve, and syringe for quick maintenance

Easy Operation
Varian sample-handling devices have simple, intuitive control interfaces, and can be controlled from the module’s keypad or from a Data System, greatly improving ease-of-use and programming capabilities.

Easy Maintenance
Special attention is given to achieving high MTBF (Mean Time Between Failure) and providing timely instrument service when needed. Varian HPLC AutoSamplers monitor syringe and injection valve operation and alert you before injection performance degrades or fails.
