The manufacturer of the Dionex AS40 Automated Sampler, Dionex is Dionex.
Refurbished Dionex AS40 automated sampler (AS 40). May be available as part of the Dionex DX-500 system and as a stand-alone unit.
The Dionex AS40 Autosampler is a low-cost, metal-free, rugged, automated, sample loading device designed especially for ion chromatography applications.

Condition: Refurbished, Certified Pre-owned
Sample Delivery Method: Positive displacement against back pressure of up to 690 kPa (100 psi)
Capacity: 11 cassettes of either six 5-mL or eight 0.5-mL PolyVials
Vial Size: 0.5 or 5 mL
Filter Pore Size: 20 micron
Minimum Volume Delivered:
0.5 mL vials: 0.17 mL per injection
5.0 mL vials: 1.7 mL per injection
External Control:
Input: Load
Output: Ready
Injections Per Vial: One, two, or three
Injection Type:
Loop: Delivers sample rapidly to sample loop (~ 4 mL/min)
Concentrator: Delivers sample against back pressure of up to 690 kPa (100 psi) at approximately 0.4 mL/min (0.5-mL vials) or 1 mL/min (5-mL vials)
Injection Mode:
Proportional: Delivers volume inversely proportional to the number of injections per vial
Constant: Delivers fixed volume independent of the number of injections per vial
Bleed Function:
On: Displaces excess sample and any trapped air through bypass valve before sampling
Off: Delivers sample and any trapped air directly to injection valve

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.
