The Dionex AS40 Autosampler is a low-cost, metal-free, rugged, automated, sample loading device designed especially for ion chromatography applications. This refurbished Dionex AS40 Automated Sampler is in great condition. It has been tested at SpectraLab Scientific. A 90 day warranty is included. Multiple available.
We are seasoned professionals in this area and we would be happy to have you speak with one of our experts here at SpectraLab. Thanks for looking and we look forward to hearing from you!
Features:
- Simple front-panel layout makes the AS40 easy to learn and use.
- Metal-free flow path eliminates corrosion and metal contamination problems.
- Accommodates disposable PolyVial™ sample vials in both 5-mL and 0.5-mL sizes.
- Filter caps automatically filter the samples during delivery.
- Sample can be loaded to loops or concentrator columns.
- Bypass valve displaces excess sample or trapped air before sampling.
- Rinse vials can be placed anywhere in the sequence.
- The output relay function indicates if and when an autosampler load was completed.
- Automatic switching power supply for universal input voltage (90–265 V ac)simplifies instrument installation and setup.
