The Sipper Module uses a peristaltic pump to pull samples into a flow cell for readings.
After the reading is taken, the sample is either returned to the user or dumped to waste.

The Sipper Module provides improved measurement accuracy, because the sam e optical
characteristics exist for both blanking and reading, and when comparing me asurements o f
different samples. Errors resulting from optical differences between individual cells are
eliminated because every reading is taken in the same vial.
