719D SERIES

Advanced Logic Dual Plate Sample Injection Instrument

The new 719D is a sample injection instrument that has been expanded to be an "all in one" autosampler for zero carryover, and increased capability for sample processing. Alcott knows you are under pressure to produce quality results with no time for error. So, the new 719D is designed to provide solutions for your front-end automation injection needs.

Performance, Productivity, Time Savings, Versatility.

Performance

Carry over (cross contamination) is typically less than 0.001% or in most cases non-detectable with an additional external needle wash station. This makes direct sample injections into mass spectrometers or other highly sensitive detection instruments advantageous. Show me the proof.

The Alcott model 719D instrument is a double plate autosampler. Accuracy is attained with injection volumes which range from 0.06µL to 2mL using partial or full loop injections.

Productivity

With this dual plate autosampler, up to 192 samples may be processed in one run.

Sample Plate Type	Number of Positions of Sample Plate	Volumes of Samples (mL)	Total Samples for 719D
Microplate	96	varies	192
8mm Vial Trays	77	1	154
12mm Vial Trays	40	2	80

Time Savings

The 719D was designed to save the user's time with speedy injection cycle times and with an open architecture. All chromatography parts are easily accessible, so maintenance, exchanging parts, repair, and sample plate exchange are quick and simple.
There is no waiting to finish a run for priority samples.
This "all in one" sample preparation autosampler alleviates time consuming manual sample prep work and uses less bench space.

Solid Phase Extraction - sample is deposited onto a trap cartridge which is installed in the sample loop.

Derivatization - The two plate feature allows for mixing samples of one plate with samples of the other plate. This new capability increases the number of possibilities for complexity of derivatizations.
Reconstitution - Diluting dry samples and mixing.
Dilution - Serially dilute and mix samples.

Versatility

Unlike most autosamplers on the market today, this dual plate instrument is designed to offer the user a variety of sample plate options. One can use microplates as well as vial trays (8mm,12mm).
The 719D fits all of your front-end automation needs. You are investing in an instrument that is not brand specific and can be used in several different applications such as HPLC, MS, LC-MS, SFC, IC, HDC, EOX, and HDC as well as any analyzer that uses FIA. Customization is welcomed for the end user or OEM possibilities.
Customization of internal and external software is available to suit your specific needs.
A wide selection of valves allows for a variety of solutions. Additional Benefits
A smaller footprint compared to other autosamplers frees up bench space.
Replacement of parts has been made economical and easy to save you money, effort, and time.
Selectable needle depth allows flexibility for using different kinds of sample plates.
Windows software is available for remote PC control.
Durable, chemically resistant case protects against damage from spills.
