MILFORD, Mass. (Oct. 24, 2008) – Thermo Fisher Scientific Inc., the
world leader in serving science, has introduced new Thermo Scientific
PocketTip(r) D.A.R.T.s(r) tips, enabling nanoliter volume dispensing on
Thermo Scientific Matrix automated systems. An internally molded
capillary pocket allows the transfer of 50-500 nL of concentrated sample
compounds suspended in Dimethyl Sulphoxide (DMSO) directly to assay
plates, saving time, reagents and labware, as well as improving data
quality with in-tip mixing.

PocketTip D.A.R.T.s tips introduce an easy, low risk and reliable method
to change the way in which current instrumentation performs critical
liquid handling tasks. Through aspiration, the capillary pocket fills
with the specified amount of compound solution and facilitates soft
in-tip mixing of sample and assay material, removing time consuming
intermediate dilution steps and adding further function to the existing
instruments. Furthermore, the unique face seal of the D.A.R.T.s tip
minimizes tip-to-tip height variations for consistent dispensing. This
innovative pipetting method makes it possible to perform assays quicker,
reduce reagent costs and prevent compound precipitation for more
accurate and precise results.

The new PocketTip D.A.R.T.s tips are ideal for all secondary compound
screening applications, such as selectivity assays, potency
determinations, cell- and enzyme-based assays and PCR primer dilutions.
