Flow Counting Cell, ≥50 µm Optical Path (CAT#: STEM-AL-7635-ZJF)

The flow counting cell is a precision optical flow cell intended for formed-element analysis in biological fluid analyzers. It is designed to guide a liquid sample through a defined optical detection channel. The construction uses optical glass, quartz glass, or sapphire crystal with bonded monolithic construction. The optical or fluidic configuration provides a controlled flow path and polished detection region for optical measurement. Its measurable characteristics are defined by the dimensional, surface, transmission, or operating parameters stated in the source. The component can be integrated through bonded or threaded external fluid connections. The design is intended to maintain repeatable optical or fluidic behavior within its stated application. Overall, the product provides a compact optical flow path for particle and cell counting.
