Agilent 8453 G1103A Spectrophotometer w/ G1120A Multicell Transport

The Agilent 8453 UV-Vis Spectrophotometer uses a photodiode array for simultaneous measurement of the complete ultra-violet to visible light spectrum in less than one second, making it extremely efficient within the lab with exceptional reliability and repeatability. With its diode-array technology, the Agilent 8453 Spectrophotometer is much faster and more sensitive than comparable conventional instruments. The Agilent 8453 UV-Vis system offers powerful data analysis and data archival to ensure compliance with good laboratory practices (GLP) and pharmacopoeia requirements.

The Agilent G1120A Multicell Transport is also included with this system. The multicell transport cell holder holds eight cells in a rack which can be held at a constant temperature with water circulated from a thermostatic bath (provided by the user). The holder is attached to the multicell transport base which contains a stepper motor to move the designated cell into the optical path. A water-driven magnetic stirrer (not included) can be fitted under the holder in one of two positions, either under the cell in the optical path, or under the cell to the left of the cell in the optical path.

The outside dimensions of individual cells must be 12.5 × 12.5 mm and the height from base of the cell to the sample area 15 mm. During an analysis, the position of individual cells is maintained by a flat spring inside each of the cell compartments. The spring alone fixes the cell and no additional fixing mechanism is needed.

All of our equipment is fully tested to perform at factory specifications before being shipped.
