Pipetting Characteristics of Serum and Serum-like Solutions versus Water

This presentation will address the difference in performance of a handheld micropipette when dispensing water versus various types of animal and human serum, as well as a serum-like dye solution. These differences are quantifiable and can be accounted for through careful experimentation and attention to physical pipetting details.

Reducing Costs by Improving Liquid handling

Lowering costs and reducing repeat testing are common interests in all areas of life science. Removing sources of variability from test processes reduces error leading to rework, lowers risk and increases reliability of results. One likely source of variability, which is easily controlled, is liquid handling.

Pipetting Comparison of DMSO Versus Aqueous Solutions as Measured Using Dual-Dye Technology

This poster examines the differences in liquid delivery by automated liquid handlers dispensing both aqueous and DMSO-based test solutions. For the study discussed herein, an ALH was first optimized to dispense aqueous test solutions, after which these optimized aqueous method(s) were used to dispense identical target volumes of both DMSO- and aqueous-based MVS Sample Solutions into microtiter plates, which were then measured with the MVS to determine actual delivered volume.

Accuracy and Precision in Low Volume Liquid Transfers

Acoustic transfer systems operate by ejecting a rapid fire stream of tiny discrete droplets, with each droplet adding a few nanoliters to the total aliquot. This makes the system digital, in the sense that volumes can be changed by adjusting the number of droplets.

Effect of Liquid Handling Quality Control on Biological Assay Performance

Molecules from a high throughput screening (HTS) campaign are often selected for further development after a single interrogation. HTS groups are also constantly challenged with improving efficiency by incorporating new technologies and complex biology. Hence, in order to obtain promising candidates, high quality assays are required.

Nanoliter Volume Pin Tool Transfers as Measured by a Dual-Dye Absorbance Method

A common trend observed in life science testing over the past several years has been the ever shrinking test volume. Increasing costs of chemical compounds and commonly used solvents has pushed high throughput screening labs towards lower working volumes, specifically in the nanoliter range.
