The MicroSip is a unique approach to autosampler design, especially optimized for very small sample volumes.  Standard autosamplers typically require many hundreds of microliters and are not always practical for SIA applications.   The MicroSip allows as little as 50 microliters of sample to be introduced into the SIA system for processing.

The MicroSip consists of a multiposition valve with proprietary PA100 1/4-28 fittings that accept disposable pipette tips rather than tubing.   The unit is designed to allow the out port to be 1-2 inches from an analyzer sample port, thus minimizing the distance the sample needs to travel.   Ideal for applications such as bioassays where sample volumes are limited and/or samples are expensive.   The sample reservoirs can also hold beads for bead injection assays, as well as reagents.   The MicroSip is ideal for MicroSI Techniques.

Notes on volume limitations: when available sample volume is as small as 50 microliters,  10 microliter of sample can routinely be injected in triplicate. With care 5 microliters can be injected if only 10 microliters of sample solution is available .
