Electrostatic device for active transfer of submicroliter samples from syringe pipettors

Electrostatic device for active transfer of submicroliter samples from syringe pipettors.

The electrostatic charger can be operated in automatic or manual mode. In automatic mode, the high voltage is controlled by means of an analog input ranging from 0–5 V, corresponding to 0–20 kV at the high voltage side of the device. In our case, a laptop running NI Labview 7.1® and a DAQCard 6062E® (National Instruments, Austin, TX, USA) was used to provide the analog control signal. The 0–5 V...

A method for parallel, automated, thermal cycling of submicroliter samples.

A large fraction of the cost of DNA sequencing and other DNA-analysis processes results from the reagent costs incurred during cycle sequencing or PCR. In particular, the high cost of the enzymes and dyes used in these processes often results in thermal cycling costs exceeding $0.50 per sample. In the case of high-throughput DNA sequencing, this is a significant and unnecessary expense. Improve...

Semiautomated Device for Batch Extraction of Metabolites from Tissue Samples

Metabolomics has become a mainstream analytical strategy for investigating metabolism. The quality of data derived from these studies is proportional to the consistency of the sample preparation. Although considerable research has been devoted to finding optimal extraction protocols, most of the established methods require extensive sample handling. Manual sample preparation can be highly effec...
