G1811A : A precision sampling robot for modern laboratories
The Agilent G1811A XY autosampler is an automation solution developed for laboratories aiming to streamline their analytical workflow, particularly in UV-Visible spectrophotometry. Thanks to its XYZ robotic arm system, it effectively replaces repetitive manual handling and delivers remarkable accuracy in vial positioning. The robotic arm operates across the X, Y, and Z axes with a precision of ±1 mm, ensuring consistent reliability in every analysis while significantly reducing the chance of manual error.
Designed to integrate perfectly with Agilent ChemStation software (version A.06.02 or later), the G1811A can be fully controlled from a PC via RS-232 interface. This software compatibility allows users to define complete sampling sequences, customize the needle's immersion depth, set pump and rinse times, and even manage partial sample return. It supports different modes of operation, including sequences for dissolution testing, offering great operational flexibility to meet various analytical protocols.
At its core, the G1811A features a stationary tray capable of accommodating up to four type 21 racks, each holding 60 vials of 9 ml. This setup allows for fully automated handling of 240 samples in a single run. The needle is equipped with a dedicated rinse station that cleans both its internal and external surfaces after every sample, dramatically reducing cross-contamination risks — a critical feature for analytical precision and data integrity.
Installation is straightforward, thanks to the modular architecture of the system. The horizontal and vertical arms, tray, rinse station, and safety shield are all simple to assemble. The compact frame, built to meet international safety standards (UL, CSA, EN), includes a rear panel with clearly accessible power and communication ports, as well as unit ID and baud rate selectors for easy configuration.
Combining high precision, large sample capacity, flexible software control, and low maintenance requirements, the Agilent G1811A stands out as a powerful instrument for today’s laboratory needs. It frees up valuable time for analysts, increases productivity, and ensures the delivery of consistent and reproducible results. This autosampler is a complete, scalable tool for laboratories seeking performance and reliability in their sample handling systems.
