S 5250 Sample Injector System S 170 EXPERT HPLC SYSTEM The Sykam S 5250 Sample Injector System is a very flexible and powerful HPLC autosampler with excellent reproducibility and linearity properties. Variable vial racks and adaptors for microtiter plates as well as a multitude of firmware options make this system highly adaptable and suitable for any analytical application. Robust Design Durable X/Y/Z-Sampling The S 5250 Sample Injector System features a mechanically durable X/Y/ZSampling-Mechanic designed for long life operation. The self-lubricating bearings keep the routine maintenance at a minimum and avoid troubles caused by dusty environments. High precision stepper motors drive the X/Y axis for accurate positioning. Microstepping mode enables a high resolution for the syringe dosing and vial positioning. vials can be used without problems. Accessibility The injection valve with sample loop and injection port can be accessed directly from the instrument Figure: Dual-Needle Injection Dual-Needle Design The Dual-Needle design of the S 5250 Sample Injector System avoids system blockages due to septum particles injected into the system. The ventilation needle pierces the septum before the injection needle moves into the sample vial (see figure on the right). As the more fragile injection needle does not need to pierce the vial septum, stronger vial caps or plastic

front without removing any protective covers. The dosing syringe can be accessed from the side of the instrument through a hinged glass panel. The exchange of the syringe can be done without the requirement of any tools. Precision & Modularity Performance The Sykam S 5250 Sample Injector System offers multiple injection modes depending on application and sample needs. Besides fixed loop overfilling and variable volume injection the instrument offers a Zero-Waste injection mode for injecting very small sample amounts by moving the sample into the middle of the sample loop.
