Chromatographers seeking to automate low to medium cost HPLC systems with an autosampler capability find the cost of most autosamplers equal or even exceed the complete system cost. The D-Star DAS-10 autosampler is priced at less than one half the cost of many competitive instruments! This autosampler represents an exciting new concept in instrument design called common sense.

The DAS-10 conforms to D-Star’s continuing effort to offer "No Frills-No Nonsense" designs. D-Star’s instrument development philosophy is to design and manufacture analytical instruments that fit specific needs in the market at prices that fit anybody’s budget. But don’t let our reasonable prices fool you. These are quality analytical instruments using innovative designs to achieve the required economies and to provide the user with problem solving tools. The development of the DAS-10 was a direct result of input from users who stressed economy and functionality.

This low cost autosampler for HPLC is ideal for those applications where there is not a large number of samples to be tested, yet automation will free the user from the simple repetitive task of multi-injections. Its small footprint is ideal for mating to D-Star’s compact HPLC systems to free-up precious bench space.

Programming is accomplished from the front panel controls and LCD display. With the embedded microprocessor, the user can program: sample size/injection volume (recommended 3 to 5 times loop volume) and the number of injections. One or more injections can be programmed from the same vial. The instrument can be monitored by the easily read front panel display.

Wash is programmable. User may select wash or no wash after each injection. An external wash reservoir provides sufficient wash solution via Teflon tubing. An internal syringe delivers the wash in sufficient quantity to minimize any cross contamination.

The DAS-10 autosampler provides an added safety feature by using electrically activated injections, not pneumatic/gas pressurized operation. A unique autoinjector design helps to minimize the overall cost of the system.

The autosampler also uses standard 11mm autosampler vials available from Chrom Tech. Micro inserts may be used for smaller sample volumes.

The autosampler may be used as a stand alone instrument or in conjunction with chromatography support software. The DAS-10 can be remotely controlled via contact closures to start the injection and initiate the data acquisition.
