Facilities & equipment

There is a large assortment of scientific facilities and equipment that is used for scientific research and industrial purposes. Besides the major well-known brands producing their models in high volume, there are many innovative companies and organisations designing and manufacturing exciting new instruments for chemical, physical and biological applications and analysis. At the same time, many suppliers and re-sell (more)ers increasingly focus on the re-use of existing used laboratory equipment. This drive towards a more circular economy offers unique opportunities for institutes and organisations to obtain valuable scientific instruments at a discount.

All products on our website are in stock and can be delivered with installation by our own service engineers. All systems are delivered with warranty! We can deliver also other modules of Agilent autoinjectors. Like Agilent 7683 with 100 vial tray 7693A Automatic Liquid Sampler The Agilent 7693A ALS (Automatic Liquid Sampler) provides reliable, fast, and precise injections for Agilent GC and GC/MS systems. Start with a tower and 16 vials. Expand to the 150 vial tray. Features 150 sample vial tray allows longer unattended operation Dual simultaneous injection saves time by doubling sample throughput Fast injection technology minimizes needle discrimination and enables use of external standards Sandwich injections of three layers eliminate manual error from internal standard, surrogate, or protectant additions Sample heater and mixer dramatically improves high molecular weight chromatographic results Heat the entire tray or cool it to sub-ambient temperatures to meet your lab’s needs Modular design allows the flexibility to easily move the sampler from GC to GC or start with a single injector and upgrade as needed Priority sample capability. There is no need to stop the sequence to add next most important sample Barcode reader allows the system to perform specific actions on mismatch, ensuring chain of custody Agilent Barcode Printing Solution. Extend the useful life of the 6890N GC by upgrading aging autoinjectors to 7693A
