Dionex AS40 automated sampler auto autosampler as-40
* DIONEX AS40-1 AUTOMATED SAMPLER
UNIT POWERS UP AND SEEMS FUNCTIONAL, WE DID NOT TEST ANY FURTHER, SO WILL BE GUARANTEED TO BE AS DESCRIBED ONLY.
VERY GOOD CONDITION WITH SIGNS OF AVERAGE USE WITH SLIGHT SCRATCHES AND SCUFFS. TOP LID IS NOT INCLUDED. OVERALL VERY CLEAN! PICTURES ARE OF THE ACTUAL UNITS.
The Dionex AS40 Autosampler is a low-cost, metal-free, rugged, automated, sample loading device designed especially for ion chromatography applications.
Key features provide performance and versatility:
* 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.
Positive displacement against backpressures of up to 690 kPa (100 psi)
11 cassettes of either six 5-mL or eight 0.5-mL PolyVials
0.5-mL vials: 0.17 mL per injection
5.0-mL vials: 1.7 mL per injection
Loop: Delivers sample rapidly to sample loop (~4 mL/min)
Concentrator: Delivers sample against backpressure of up to 690 kPa (100 psi) at ~0.4 mL/min (0.5-mL vials) or 1 mL/min (5-mL vials)
Proportional: Delivers volume inversely proportional to the number of injections per vial
Constant: Delivers fixed volume independent of the number of injections per vial
On: Displaces excess sample and any trapped air through bypass valve before sampling
Off: Delivers sample and any trapped air directly to injection valve
Automatic switching power supply for universal input voltage (90 265 V ac), (47 63 Hz).
