Good for samples with <100uL volume.
Rating: 4.7

  • Application Area: Targeted Metabolomics

"With the progressively reducing volume of sample available for extraction and analysis of molecules in biological matrix, the instrument is effective for automated sample preparation. It might take a while to get used to how it operate. Once one has master that, it is worth the time as it ease the sample preparation and extraction procedure. One of the downside to the instrument is that it takes time to run a batch of samples, especially for a step that include other mini-steps like mixing, heating, syringe pumping, and syringe rinsing. On the other hand, one can load the samples and let the instrument run while doing other works."

Gravimetric dilutions with minimal hands-on time
Rating: 5.0

  • Application Area:Workhorse for gravimetric dilutions

"The 7696A Sample Prep Workbench is used for most of the gravimetric dilutions performed in the lab. Having a dedicated weighing station (which is not so common for liquid handling robots) allows for easy protein concentration determination. Runs perfectly well over night."

The Agilent 7696A Sample Prep Workbench automates many routine sample preparation steps for HPLC, GC, LC/MS and GC/MS. This significantly reduces errors associated with manual sample prep leading to increased precision and less rework. Because the 7696A is used offline, it can prepare samples in batches so they are ready for analysis. Simply load the trays into the Agilent GC or LC autosampler and start the sequence.
