HPLC autosampler S 6250

GPC/SEC

The S 6250 and S 6300 auto samplers are very flexible and powerful HPLC and GPC/SEC auto samplers with excellent reproducibility and linearity properties. Variable vial racks and adaptors for microtiter plates as well as a multitude of firmware options make this systems highly adaptable and suitable for any analytical application. Auto sampler S 6250 (60 samples) is in a small housing and the auto sampler S 6300 (120 samples) is in a slightly larger housing (see technical specifications). Robust design Durable X/Y/Z-sampling The S 6250 and S 6300 auto samplers features a mechanically durable X / Y / Z - sampling-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. Micro stepping mode enables a high resolution for the syringe dosing and vial positioning.S6250 HPLC Autosampler Schambeck SFD Dual-needle design The dual-needle design of the S 6250 and S 6300 auto samplers 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 frag-ile injection needle does not need to pierce the vial septum, stronger vial caps or plastic vials can be used without problems.S6250 HPLC Autosampler Schematic Schambeck SFD GmbH Accessibility The injection valve with sample loop and injection port can be accessed directly from the instrument front without removing any protective covers.
