The manual transfer of liquid samples is part of daily activities throughout the analytical laboratory. The accurate and precise transfer of liquid samples can be critical to the analytical results. Liquid samples with high viscosities pose several challenges to achieving accurate and precise delivery of desired volumes.

Automating the accurate transfer of such viscous liquids would lend support to the quality of the analytical procedure, help ensure the high quality of the resulting data, and free the analyst from performing a tedious manual task. A robotic autosampler commonly used for sample introduction in GC or HPLC can be used to perform a wide variety of sample preparation techniques.
The sampler can be configured as part of a GC or LC system or as a stand-alone bench-top workstation. An analytical balance can be included to provide weight verification of liquid transfers.
